Sentinel Steam Shunter British Tar Products Ann(DCC-Fitted)

Sentinel Steam Shunter British Tar Products 'Ann'(DCC-Fitted)

Details:

The 100hp Sentinel Pre-War ‘Ann’ in Plain Green brings a distinctive industrial steam locomotive to the OO gauge model railway. Reproduced in 1:76 scale, this highly detailed model represents the British Tar Products locomotive and features an open cab back sheet, narrow chimney, high-mounted sandboxes and toolbox. The centre-mounted radius rods and vacuum-fitted equipment add further detail, while the diecast metal and plastic construction combines with a smooth and powerful mechanism. An E24 DCC decoder socket and MoPower stay-alive provide DCC upgrade potential and reliable running, complemented by a museum-quality paint finish.

Historical Background

Unlike many industrial railway locomotives, the Sentinel steam shunter evolved from road vehicle technology rather than conventional railway locomotive designs. Its origins can be traced to Alley & MacLellan Ltd of Polmadie, Glasgow, founded in 1875 and later known as Sentinel Waggon Works Ltd.

In 1906, the company introduced its first vertical-boiler steam road waggon. Powered by a two-cylinder undertype engine and chain drive, these vehicles were efficient and relatively simple to operate. Around twenty years later, Sentinel Waggon Works adapted the concept for its first 0-4-0 railway locomotive prototype.

The Sentinel steam shunter quickly became popular with industrial operators and crews. Its short wheelbase allowed it to negotiate the tight curves found on many industrial railway systems, while rapid steam raising, good fuel economy and straightforward operation made it particularly practical for industrial use.

A variety of Sentinel steam locomotive designs were produced. Before the Second World War, the two-cylinder vertical-engine ‘BE’ was the most widely built type, including an example supplied to the LMS. Despite its apparently conventional domeless appearance, the ‘BE’ housed its vertical cylinders beneath a distinctive round cover at the front of the locomotive. A large water tank occupied much of the space normally associated with a locomotive boiler, providing both a substantial water capacity and additional weight for improved adhesion.

After the Second World War, improved designs featured metal-clad tanks and cylinders with access hatches for maintenance. Production of Sentinel steam shunters continued until 1958, after which the company concentrated on internal combustion locomotives. The Sentinel name was subsequently carried forward by Rolls-Royce through the production of diesel locomotives.

Although production ended in 1958, many Sentinel steam locomotives remained in industrial service for decades. Their survival in preservation has also been remarkable, with numerous examples preserved at railways and museums across the UK, including several that remain operational.
