Alley & MacLellan, Sentinel Works, Jessie Street Glasgow

Alley & MacLellan was founded in 1875 and was based in Polmadie, Glasgow. This company continued in operation until the 1950s. Initially manufacturing valves and compressors for steam engines, and later whole steamships, Alley & MacLellan acquired Simpson and Bibby of

and it continued under a separate company (see below), and in 1918 the company also opened a third factory in Worcester specialising in valve manufacture. Both factory buildings were prefabricated in Glasgow for local assembly and in both cases core Scottish employees transferred to the new sites. 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.

Move to Shrewsbury

The 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

, 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 four-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 steam wagons 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

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 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 locomotives 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 did not approve. There had been a change of opinion 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.

of Switzerland. The gyros were principally a 3ton 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 3,000rpm when fully 'charged;' and 1,800rpm before recharging. Recharging took 2minutes and the locomotive could work for around 30 minutes before recharging. It weighed 34tons and had a maximum speed of . This machine was specially built for the
