Sentinel Waggon Works Ltd was a British company based in Shrewsbury, Shropshire that made steam-powered lorries, railway locomotives, and later, diesel engined lorries and locomotives.

History

Alley & MacLellan, Sentinel Works, Jessie Street Glasgow

The company began life about 1875 as Alley & MacLellan based in Polmadie, Glasgow. They moved from Polmadie Road to the nearby Jessie Street where they continued in operation until the 1950s. Alley & MacLellan began producing steam road vehicles in 1906 when they introduced a5 ton vertical-boiler wagon, which featured a 2-cylinder undertype engine and chain drive. Around 1915 Alley & McLellan moved the steam wagon production to a new factory in England and it continued under a separate company (see below). However, Alley & MacLellan continued to operate in the original Sentinel Works in Jessie Street, Glasgow until the 1950s. They produced a wide range of engineering products including compressors, valves, etc. The ‘Sentinel’ name continued to be used for the products of the original Glasgow works until the mid 20th Century.

Perhaps the most surprising fact is that the Sentinel Works in Glasgow, though a significant distance from the River Clyde, produced almost 500 small ships and boats. The vast majority of these vessels were built as ‘knock downs’ – i.e. assembled at the Jessie Street works using nuts and bolts, then dismantled and shipped as parts in crates to their client destination where they were re-assembled using rivets. At least one Alley & McLellan ship still exists – the motor vessel (originally steam ship) Chauncy Maples built at Jessie Street in 1899 and reassembled on Lake Nyasa (now Lake Malawi) in 1901. Alley & MacLellan continued in operation, though owned firstly by Glenfield & Kennedy, Kilmarnock, then G & J Weir, Glasgow, until the 1950s.

The original Sentinel Works in Jessie Street, Glasgow is still in existence in 2009 though now in a very derelict condition. The design offices and pattern shop is listed category A as a building of significant national importance. It was the first steel-reinforced concrete building in Scotland.

Move to Shrewsbury

1928 LNER Sentinel-Cammell steam railcarLNER Sentinel-Cammell steam railcar

A new company Sentinel Waggon Works Ltd was formed when steam wagon production was switched to a new factory, opened at Shrewsbury in 1915. There were several other slight changes to the name over the company’s lifetime when further infusions of working capital were required to obviate financial problems.

Alley & MacLellan’s early wagon was so successful that it remained in production with relatively few updates until the launch of Sentinel’s famous Super in 1923. The company also produced steam railway locomotives and railcars, for railway companies and industrial customers.

In 1917, the company was bought by William Beardmore & Co., Ltd.

Sentinel Waggon Works (1920) Ltd

In 1920, after financial problems, the company was reorganised as Sentinel Waggon Works (1920) Ltd. The Sentinel ‘Super’ model that followed in 1923 was assembled in a radical new plant at Shrewsbury, with a flow line based on Henry Ford’s Model T factory at Highland Park, Michigan, with 1,550 vehicles produced.

Sentinel, along with Foden, dominated the steam market, but the 1930s saw the demise of both companies’ ranges as new legislation forced the development of lighter lorries, Sentinel surviving the longest.

In 1934 Sentinel launched a new and advanced steamer – the S type which had a single-acting 4-cylinder underfloor engine with longitudinal crankshaft and an overhead worm-drive axle. Their Sentinel Waggon Works’ design of 1935 led to the production of 3,750 Sentinel ‘Standards’ in the seventeen years that followed, the biggest selling steam lorry ever. It was lighter and featured a modernised driver’s cab with a set-back boiler and was available in four, six and eight-wheel form, designated S4, S6 and S8. In spite of its sophisticated design, however, it could not compete with contemporary diesel trucks for all-round convenience and payload capacity, and was phased out in the late 1930s. It was not the end of Sentinel’s involvement with steam, however; the company built about 100 “S” type vehicles for export to Argentina as late as 1950, for use by the Río Turbio coal mine. It has been stated that Sentinel were never paid for the last batch of the Río Turbio production run. At least two of the Río Turbio waggons survive in Argentina to this day.

In 1946 Thomas Hill’s signed an agency agreement with Sentinel for repair and maintenance of diesel vehicles. In 1947 Sentinel offered to extend the agreement for diesel vehicles to include the steam locomotives and an agency was accepted by Thomas Hill for sales and servicing.

Sentinel (Shrewsbury) Ltd

In 1947 the company became Sentinel (Shrewsbury) Ltd, and had developed a new range of diesel lorries. Despite Sentinel’s superbly engineered vehicles, sales diminished throughout the 1950s, and by 1956 the company was forced to cease lorry production. The factory was acquired by Rolls-Royce for diesel engine production, and the remaining stock of parts and vehicles was taken over by Sentinel’s chief dealer, North Cheshire Motors Ltd of Warrington, who formed a new company, Transport Vehicles (Warrington) Ltd, in 1957 to produce Sentinel-based designs under the TVW name.

In 1963 Thomas Hill’s decided to renew the loco agreement and relinquish the diesel vehicle agency, concentrating all efforts on the steam locomotive work.

Despite the various interesting developments, Rolls Royce did not consider railway locomotives to be part of their core business. They had agreed to complete all steam locos on order, and four steam receiver locos ordered by Dorman Long in 1956, but only after much consideration did Rolls-Royce finally agree at the end of 1957 to design and build a diesel locomotive of similar weight and power to the 200 hp (150 kW) steam loco that had sold so well. Thomas Hill’s would assist in the design and development of these diesel machines and would be the Sole distributor.

Last steam locomotives

In 1958 the last two Sentinel steam locos were delivered marking the end of an era. Two of the newly developed steam receiver locos were delivered and proved very satisfactory in service, but Dorman Long were not happy. There had been a change of heart among their engineers as well as a change of circumstances, and they were now favouring diesel locomotives. The last two steam receiver locos were built but never delivered and ultimately all four were converted to diesel hydraulic.

Diesel production commences

The prototype Sentinel diesel locomotive was built and ready to commence trials on the former Shropshire & Montgomeryshire Railway (then under military control) early in 1959. It met with the approval and enthusiasm of the Company’s prospective customers and before the end of the year 17 locomotives had been sold and delivered. The company was ready to produce a maximum of four locomotives a month.

By 1963 four different Sentinel diesel models were being produced, commencing with the 34 ton chain drive 0-4-0 powered by the Rolls-Royce C6SFL six-cylinder engine of 233 bhp (174 kW) (gross) (later uprated to 255 bhp (190 kW)). This was followed within a year by a 48 ton 0-6-0 rod coupled machine, fitted with a Rolls-Royce C8SFL eight-cylinder engine of 311 bhp (232 kW) (gross) (later uprated to 325 bhp (242 kW)). Between 1963 and 1966 a fleet of these diesel locomotives, eventually numbering five 0-6-0s and 18 0-4-0s, was supplied to the Manchester Ship Canal Company for use on the navigation’s private railway network.

These Sentinels demonstrated their suitability for heavy work, but heavier and more powerful locos were called for, particularly by the steel industry, and before the end of 1963 a 74 ton 0-8-0 powered by 2 x C8SFL engines and a 40 ton 0-4-0 fitted with a C8SFL engine had been added to the range.

Sentinel Steelman

A shaft drive 600 hp (450 kW) 0-6-0 machine was now being developed at Shrewsbury to use the new DV8T engine. Considerable interest in this loco was expressed by Stewart and Lloyds mineral division at Corby who were operating more than 20 steam locos, mainly of the Austerity type. This new locomotive Steelman was eventually delivered to Corby in late 1967, about two years overdue. The prototype locomotive proved satisfactory and three more were ordered by Stewart and Lloyds and one by Richard Thomas and Baldwins, Scunthorpe. With Stewart and Lloyds’ programme to replace more than 20 steam locos over the next few years the future for Steelman looked good.

Unfortunately for the Company and Rolls-Royce, British Railways, seeing a potential for their Swindon-built class 14 diesel hydraulic locomotives made Stewart and Lloyds an offer of 26 locomotives around three years old at a fraction of their original cost. The Class 14 locomotive had proved rather a white elephant for B.R. but powered by a 650 hp (480 kW) Paxman, Voith Transmission, a rod coupled 0-6-0 capable of doing the work required, it was an offer that Stewart and Lloyds could hardly refuse. New locomotive sales were declining anyway, and the release of such locos onto the industrial market at such prices was disastrous, and regrettably no further “Steelman” locos were built at Shrewsbury.

This was not to be the end of the Steelman. Some 12 years later ICI Billingham wanted two heavy locomotives to replace their ageing Yorkshire Janus locomotives. Their stated wish was to buy the best and most up to date equipment available and in their efforts to achieve this aim, their engineers visited many industrial sites, and steelworks in particular. Their requirements were discussed with all UK locomotive manufacturers, and the final outcome of their investigations was an order for an updated version of the “Sentinel Steelman locomotive”. This order was subsequently increased to two machines which were delivered toward the end of 1981.

UK sales of Sentinel locos were now fewer than 10 per year, their only overseas success had been to license the assembly of 36 0-6-0 locomotives by Sorefame for the Portuguese Railways in 1965/6. These locomotives became the CP Class 1150.

In 1925 the New Zealand Railways Department bought one Sentinel-Cammell steam railcar which became part of its RM class.

Between 1925 and 1932 the London and North Eastern Railway bought 80 Sentinel steam railcars and four were supplied to the LNER-controlled Cheshire Lines Committee.

In 1928 Palestine Railways bought two Sentinel-Cammell articulated steam railcars for local services. Each unit had two cars articulated over three bogies. Palestine Railways found the railcar format inflexible, as if passenger numbers exceeded the capacity of a train it was not practical to couple up an extra coach. In 1945 PR removed the Sentinel engines and converted the railcars to ordinary coaching stock.

In 1933 the Southern Railway bought a Sentinel-Cammell steam railcar for use on the Devil’s Dyke branch, in East Sussex. Although operationally successful, the single railcar was not large enough to meet the needs of this line. It was transferred away from the line in March 1936 and tried in other areas, but was withdrawn in 1940.

In 1951 Egyptian National Railways bought 10 articulated steam railcars. Each had three carriage bodies articulated over four bogies. One is preserved by the Quainton Railway Society at the Buckinghamshire Railway Centre, England.

Specials

The Doble Shunter

LMS Sentinel 7192 – so-called as it was fitted with an Abner Doble boiler

The Double Locomotive

A special locomotive was produced at Sentinel, for Dorman Long and named “Princess”. It consisted of 2 x 0-6-0 chassis coupled together to articulate. One unit carried the cab, a 5 drum oil-fired Woolnough boiler and two 100 hp (75 kW) engines. The other unit housed the water and fuel tanks and also two more 100 hp (75 kW) engines providing a total of 400 hp (300 kW). It was considered a magnificent machine by the staff but unfortunately was the only one of its kind ever built.

The Gyro locomotive

Another special was the NCB Gyro or Electrogyro Locomotive. Based on a 200 hp (150 kW) 4-wheeled 0-4-0 frame fitted with two “gyro units” (see Flywheel energy storage) made byMaschinenfabrik Oerlikon of Switzerland. The gyros were principally a 3 ton horizontal flywheel enclosed in a vessel filled with low pressure hydrogen. A vertically mounted three-phase squirrel-cage electric motor/generator was directly coupled to each flywheel shaft. The motor took its power from a side-mounted supply at static posts via a four-contact swinging arm extended or retracted pneumatically by the driver. Power could only be taken whilst the loco was stationary alongside one of these posts. When the gyros had reached the required speed, the driver would retract the contact arm, switch the motor to generation and controlled the locomotive in a similar way to a diesel-electric loco. Charging posts had to be strategically placed around the site. A contact arm was provided on each side of the locomotive, although it is not clear if posts were installed on one or both sides of the track. Each gyro operated between 3,000 rpm when fully ‘charged;’ and 1,800 rpm before recharging. Recharging took 212 minutes and the locomotive could work for around 30 minutes before recharging. It weighed 34 tons and had a maximum speed of 15 mph (24 km/h).

This machine was specially built for the National Coal Board (NCB) at Seaton Delaval. The intention was to investigate the use of gyroscopic storage as a potential method for a flameproof and emissions-free underground locomotive. It operated very satisfactorily but was eventually taken out of service because of site development and its restricted field of operation. In April 1965 it was converted for the NCB to a diesel hydraulic machine.

The Receiver Locomotives

The Receiver Locomotives were another special type built just for Dorman Long and were based on the idea of a Fireless locomotive.

Preservation

Road vehicles

A number of Sentinel steam waggons and tractors exist in preservation in the UK—about 117 as of 2008. For example, Preserved Sentinel Super steam wagon No. 5676. They are often shown at steam fairs in the UK. For more information see the Sentinel Drivers Club website. A number also exist in Australia and other countries.

Railway locomotives

Sentinel was een vrachtwagenmerk uit Engeland, Schotland.

Oprichting

Sentinel werd opgericht in 1906 in Glasgow. Het eerste type vrachtwagen was een stoomwagen met kettingaandrijving en vijf ton laadvermogen. Deze wagen was zo’n succes dat hij zonder wijzigingen tot 1923 in productie bleef. In datzelfde jaar opende Sentinel ook een tweede fabriek in Shrewsbury.

Modellen

Sentinel stond bekend om modellen van hoge kwaliteit en voorzien van de nieuwste technische snufjes van die tijd. Sentinel ging pas vrij laat in vergelijking met andere fabrieken, na een financiële dip in 1934, over op het gebruik van diesel– of benzinemotoren in plaats van stoommotoren.

Super

In 1920 bracht Sentinel een revolutionaire wagen uit genaamd “Super”. Dit was een vrachtwagen met krukasdifferentieel, dubbele kettingaandrijving en twee versnellingen, iets dat nog zeer uniek was in die tijd. Door de tweede versnelling kon hij goed snelheid maken op zowel heuvelachtig als vlak terrein. Deze auto had een laadvermogen van zeven ton.

DG

Sinds 1923 kwam Sentinel met de DG-serie. Deze serie had de mogelijkheid om een aanhanger toe te voegen, en was ook in een drie- en vierasuitvoering verkrijgbaar. Dit voertuigtype stond bekend als de meest efficiënte stoomwagen uit de jaren twintig.

S-type

Vanaf 1934 begon Sentinel gebruik te maken van dieselmotoren. In de S-type werd een viercilinderdieselmotor geplaatst die de vrachtwagen via de achteras aandreef. Dit model was leverbaar in een vier-, zes- en achtwieleruitvoering, er wordt dan ook gesproken over de S4, S6 of de S8.

DV

De DV-serie werd vanaf 1948 op de markt gebracht. Het was een type lichte bakwagen met twee of drie assen. Het opmerkelijke was dat deze vrachtwagen drie zitplaatsen had en een benzinemotor in plaats van een diesel.

Overname

Ondanks de goede verkoopcijfers besloot de raad van bestuur in 1956 de fabrieken te verkopen aan Rolls-Royce, dat de fabrieken uiteindelijk in 1957 sloot. Sommige Sentineldealers besloten verder te gaan. Deze gebruikten daarvoor de naam TVW Sentinel (Transport, Vehicles Warrington) en dit samenwerkingsverband verzorgde nog enkele jaren het onderhoud voor de Sentinel wagens. Er zijn echter geen nieuwe modellen meer gemaakt.

Museum

Hoewel de meeste modellen van Sentinel in musea staan is het bekend dat in Argentinië nog dagelijks enkele honderden Sentinel Super vrachtwagens hun werk doen, dit mede doordat de levensduur van de wagens door hun duurzaamheid zeer hoog is.

Sentinel Waggon Works Ltd was a British company based in Shrewsbury, Shropshire that made steam-powered lorries, railway locomotives, and later, diesel engined lorries and locomotives.

History

Alley & MacLellan, Sentinel Works, Jessie Street Glasgow

The company began life about 1875 as Alley & MacLellan based in Polmadie, Glasgow. They moved from Polmadie Road to the nearby Jessie Street where they continued in operation until the 1950s. Alley & MacLellan began producing steam road vehicles in 1906 when they introduced a 5 ton vertical-boiler wagon, which featured a 2-cylinder undertype engine and chain drive. Around 1915 Alley & McLellan moved the steam wagon production to a new factory in England and it continued under a separate company (see below). However, Alley & MacLellan continued to operate in the original Sentinel Works in Jessie Street, Glasgow until the 1950s. They produced a wide range of engineering products including compressors, valves, etc. The ‘Sentinel’ name continued to be used for the products of the original Glasgow works until the mid 20th Century.

1906 Sentinel 23GT-Sent-1914

Perhaps the most surprising fact is that the Sentinel Works in Glasgow, though a significant distance from the River Clyde, produced almost 500 small ships and boats. The vast majority of these vessels were built as ‘knock downs’ – i.e. assembled at the Jessie Street works using nuts and bolts, then dismantled and shipped as parts in crates to their client destination where they were re-assembled using rivets. At least one Alley & McLellan ship still exists – the motor vessel (originally steam ship) Chauncy Maples built at Jessie Street in 1899 and reassembled on Lake Nyasa (now Lake Malawi) in 1901. Alley & MacLellan continued in operation, though owned firstly by Glenfield & Kennedy, Kilmarnock, then G & J Weir, Glasgow, until the 1950s.

The original Sentinel Works in Jessie Street, Glasgow is still in existence in 2009 though now in a very derelict condition. The design offices and pattern shop is listed category A as a building of significant national importance. It was the first steel-reinforced concrete building in Scotland.

A new company Sentinel Waggon Works Ltd was formed when steam wagon production was switched to a new factory, opened at Shrewsbury in 1915. There were several other slight changes to the name over the company’s lifetime when further infusions of working capital were required to obviate financial problems.

1912 Sentinel Standard

Alley & MacLellan’s early wagon was so successful that it remained in production with relatively few updates until the launch of Sentinel’s famous Super in 1923. The company also produced steam railway locomotives and railcars, for railway companies and industrial customers.

In 1917, the company was bought by William Beardmore & Co., Ltd.

Sentinel Waggon Works (1920) Ltd

In 1920, after financial problems, the company was reorganised as Sentinel Waggon Works (1920) Ltd. The Sentinel ‘Super’ model that followed in 1923 was assembled in a radical new plant at Shrewsbury, with a flow line based on Henry Ford’s Model T factory at Highland Park, Michigan, with 1,550 vehicles produced.

1917 Sentinel Steam Bus

Sentinel, along with Foden, dominated the steam market, but the 1930s saw the demise of both companies’ ranges as new legislation forced the development of lighter lorries, Sentinel surviving the longest.

In 1934 Sentinel launched a new and advanced steamer – the S type which had a single-acting 4-cylinder underfloor engine with longitudinal crankshaft and an overhead worm-drive axle. Their Sentinel Waggon Works’ design of 1935 led to the production of 3,750 Sentinel ‘Standards’ in the seventeen years that followed, the biggest selling steam lorry ever. It was lighter and featured a modernised driver’s cab with a set-back boiler and was available in four, six and eight-wheel form, designated S4, S6 and S8. In spite of its sophisticated design, however, it could not compete with contemporary diesel trucks for all-round convenience and payload capacity, and was phased out in the late 1930s. It was not the end of Sentinel’s involvement with steam, however; the company built about 100 “S” type vehicles for export to Argentina as late as 1950, for use by the Río Turbio coal mine. It has been stated that Sentinel were never paid for the last batch of the Río Turbio production run. At least two of the Río Turbio waggons survive in Argentina to this day.

In 1946 Thomas Hill’s signed an agency agreement with Sentinel for repair and maintenance of diesel vehicles. In 1947 Sentinel offered to extend the agreement for diesel vehicles to include the steam locomotives and an agency was accepted by Thomas Hill for sales and servicing.

Sentinel (Shrewsbury) Ltd

In 1947 the company became Sentinel (Shrewsbury) Ltd, and had developed a new range of diesel lorries. Despite Sentinel’s superbly engineered vehicles, sales diminished throughout the 1950s, and by 1956 the company was forced to cease lorry production. The factory was acquired by Rolls-Royce for diesel engine production, and the remaining stock of parts and vehicles was taken over by Sentinel’s chief dealer, North Cheshire Motors Ltd of Warrington, who formed a new company, Transport Vehicles (Warrington) Ltd, in 1957 to produce Sentinel-based designs under the TVW name.

In 1963 Thomas Hill’s decided to renew the loco agreement and relinquish the diesel vehicle agency, concentrating all efforts on the steam locomotive work.

Rolls-Royce agree to build diesel locomotives

Despite the various interesting developments, Rolls Royce did not consider railway locomotives to be part of their core business. They had agreed to complete all steam locos on order, and four steam receiver locos ordered by Dorman Long in 1956, but only after much consideration did Rolls-Royce finally agree at the end of 1957 to design and build a diesel locomotive of similar weight and power to the 200 hp (150 kW) steam loco that had sold so well. Thomas Hill’s would assist in the design and development of these diesel machines and would be the Sole distributor.

Last steam locomotives

In 1958 the last two Sentinel steam locos were delivered marking the end of an era. Two of the newly developed steam receiver locos were delivered and proved very satisfactory in service, but Dorman Long were not happy. There had been a change of heart among their engineers as well as a change of circumstances, and they were now favouring diesel locomotives. The last two steam receiver locos were built but never delivered and ultimately all four were converted to diesel hydraulic.

Diesel production commences

The prototype Sentinel diesel locomotive was built and ready to commence trials on the former Shropshire & Montgomeryshire Railway (then under military control) early in 1959. It met with the approval and enthusiasm of the Company’s prospective customers and before the end of the year 17 locomotives had been sold and delivered. The company was ready to produce a maximum of four locomotives a month.

1923 SEntinel V136-p019

By 1963 four different Sentinel diesel models were being produced, commencing with the 34 ton chain drive 0-4-0 powered by the Rolls-Royce C6SFLsix-cylinder engine of 233 bhp (174 kW) (gross) (later uprated to 255 bhp (190 kW)). This was followed within a year by a 48 ton 0-6-0 rod coupled machine, fitted with a Rolls-Royce C8SFL eight-cylinder engine of 311 bhp (232 kW) (gross) (later uprated to 325 bhp (242 kW)). Between 1963 and 1966 a fleet of these diesel locomotives, eventually numbering five 0-6-0s and 18 0-4-0s, was supplied to the Manchester Ship Canal Company for use on the navigation’s private railway network.

1923 SEntinel V136-p612

These Sentinels demonstrated their suitability for heavy work, but heavier and more powerful locos were called for, particularly by the steel industry, and before the end of 1963 a 74 ton 0-8-0 powered by 2 x C8SFL engines and a 40 ton 0-4-0 fitted with a C8SFL engine had been added to the range.

Sentinel Steelman

A shaft drive 600 hp (450 kW) 0-6-0 machine was now being developed at Shrewsbury to use the new DV8T engine. Considerable interest in this loco was expressed by Stewart and Lloyds mineral division at Corby who were operating more than 20 steam locos, mainly of the Austerity type. This new locomotive Steelman was eventually delivered to Corby in late 1967, about two years overdue. The prototype locomotive proved satisfactory and three more were ordered by Stewart and Lloyds and one by Richard Thomas and Baldwins, Scunthorpe. With Stewart and Lloyds’ programme to replace more than 20 steam locos over the next few years the future for Steelman looked good.

1924 sEntinel V137-p284b

1924 sEntinel V137-p284b

Unfortunately for the Company and Rolls-Royce, British Railways, seeing a potential for their Swindon-built class 14 diesel hydraulic locomotives made Stewart and Lloyds an offer of 26 locomotives around three years old at a fraction of their original cost. The Class 14 locomotive had proved rather a white elephant for B.R. but powered by a 650 hp (480 kW) Paxman, Voith Transmission, a rod coupled 0-6-0 capable of doing the work required, it was an offer that Stewart and Lloyds could hardly refuse. New locomotive sales were declining anyway, and the release of such locos onto the industrial market at such prices was disastrous, and regrettably no further “Steelman” locos were built at Shrewsbury.

1924-Super-Sentinel

1924-Super-Sentinel

This was not to be the end of the Steelman. Some 12 years later ICI Billingham wanted two heavy locomotives to replace their ageing Yorkshire Janus locomotives. Their stated wish was to buy the best and most up to date equipment available and in their efforts to achieve this aim, their engineers visited many industrial sites, and steelworks in particular. Their requirements were discussed with all UK locomotive manufacturers, and the final outcome of their investigations was an order for an updated version of the “Sentinel Steelman locomotive”. This order was subsequently increased to two machines which were delivered toward the end of 1981.

UK sales of Sentinel locos were now fewer than 10 per year, their only overseas success had been to license the assembly of 36 0-6-0 locomotives by Sorefame for the Portuguese Railways in 1965/6. These locomotives became the CP Class 1150.

  • In 1928 Palestine Railways bought two Sentinel-Cammell articulated steam railcars for local services. Each unit had two cars articulated over three bogies. Palestine Railways found the railcar format inflexible, as if passenger numbers exceeded the capacity of a train it was not practical to couple up an extra coach. In 1945 PR removed the Sentinel engines and converted the railcars to ordinary coaching stock.
  • In 1933 the Southern Railway bought a Sentinel-Cammell steam railcar for use on the Devil’s Dyke branch, in East Sussex. Although operationally successful, the single railcar was not large enough to meet the needs of this line. It was transferred away from the line in March 1936 and tried in other areas, but was withdrawn in 1940.

The Double Locomotive

A special locomotive was produced at Sentinel, for Dorman Long and named “Princess”. It consisted of 2 x 0-6-0 chassis coupled together to articulate. One unit carried the cab, a 5 drum oil-fired Woolnough boiler and two 100 hp (75 kW) engines. The other unit housed the water and fuel tanks and also two more 100 hp (75 kW) engines providing a total of 400 hp (300 kW). It was considered a magnificent machine by the staff but unfortunately was the only one of its kind ever built.

The Gyro locomotive

Another special was the NCB Gyro or Electrogyro Locomotive. Based on a 200 hp (150 kW) 4-wheeled 0-4-0 frame fitted with two “gyro units” (see Flywheel energy storage) made by Maschinenfabrik Oerlikon of Switzerland. The gyros were principally a 3 ton horizontal flywheel enclosed in a vessel filled with low pressure hydrogen. A vertically mounted three-phase squirrel-cage electric motor/generator was directly coupled to each flywheel shaft. The motor took its power from a side-mounted supply at static posts via a four-contact swinging arm extended or retracted pneumatically by the driver. Power could only be taken whilst the loco was stationary alongside one of these posts. When the gyros had reached the required speed, the driver would retract the contact arm, switch the motor to generation and controlled the locomotive in a similar way to a diesel-electric loco. Charging posts had to be strategically placed around the site. A contact arm was provided on each side of the locomotive, although it is not clear if posts were installed on one or both sides of the track. Each gyro operated between 3,000 rpm when fully ‘charged;’ and 1,800 rpm before recharging. Recharging took 212 minutes and the locomotive could work for around 30 minutes before recharging. It weighed 34 tons and had a maximum speed of 15 mph (24 km/h).

This machine was specially built for the National Coal Board (NCB) at Seaton Delaval. The intention was to investigate the use of gyroscopic storage as a potential method for a flameproof and emissions-free underground locomotive. It operated very satisfactorily but was eventually taken out of service because of site development and its restricted field of operation. In April 1965 it was converted for the NCB to a diesel hydraulic machine.
