GWR No. 12 is a Sentinel geared steam locomotive which was built for the Great Western Railway and delivered in 1926. Its Sentinel works number is 6515. [1] It was equipped to work train vacuum brakes and to provide steam heat for passenger trains. Initially, it was based at Swindon and used to work trains on the Malmesbury branch. Later, it worked at Brentford Goods Yard. These trials were not a great success and the locomotive was withdrawn in December 1926 and returned to Sentinel in January 1927. [2]

Rebuilding

The locomotive was rebuilt by Sentinel with a larger boiler in 1927. It then underwent further trials as follows:

Withdrawal

In 1958, the locomotive was withdrawn. The boiler and parts of the engine were removed and it was used as a brake van. In 1972, it was condemned and was then bought for preservation and moved to the Buckinghamshire Railway Centre at Quainton. [2]

Restoration

Restoration took seven years and included fitting a reconditioned boiler and engine. The engine was first steamed in preservation on 26 August 1979. In 1981, vacuum brake equipment was refitted for passenger train working. [2]

Visits

The locomotive has visited other sites since restoration. In May 2001, it moved to Rosemary Vineyards on the Isle of Wight, and then on to the Lavender Line. In June 2008, it returned to Quainton. Since July 2012, it has been working on the Chinnor and Princes Risborough Railway, where it is expected to stay until September 2012. [2] On 15/16 September 2012 it will make a brief visit to Didcot Railway Centre for the "All in a Day's Work" steam gala. [1] In September 2019 the locomotive visited Cholsey & Wallingford Railway for the Sentinel Gala. [3]

The Great Western Railway 4000 or Star were a class of 4-cylinder 4-6-0 passenger steam locomotives designed by George Jackson Churchward for the Great Western Railway (GWR) in 1906 and introduced from early 1907. The prototype was built as a 4-4-2 Atlantic. They proved to be a successful design which handled the heaviest long-distance express trains, reaching top speeds of 90 mph (145 km/h), and established the design principles for GWR 4-cylinder classes over the next twenty-five years.

The Cambrian connected with two larger railways with connections to the northwest of England via the London and North Western Railway, and the Great Western Railway for connections between London and Wales. The Cambrian Railways amalgamated with the Great Western Railway on 1 January 1922 as a result of the Railways Act 1921. The name is continued today in the route known as the Cambrian Line.

The Great Western Railway 2900 Class or Saint Class, which was built by the Great Western Railway's Swindon Works, incorporated several series of 2-cylinder passenger steam locomotives designed by George Jackson Churchward and built between 1902 and 1913 with differences in the dimensions. The majority of these were built as 4-6-0 locomotives; but thirteen examples were built as 4-4-2. They proved to be a highly successful class which established the design principles for GWR 2-cylinder classes over the next fifty years, and influenced similar classes on other British railways.

A steam railcar is a rail vehicle that does not require a locomotive as it contains its own steam engine. The first steam railcar was an experimental unit designed and built in 1847 by James Samuel and William Bridges Adams. In 1848, they made the Fairfield steam carriage that they sold to the Bristol and Exeter Railway, who used it for two years on a branch line.

The Wallingford railway branch line was a 2.5 mi (4.0 km) branch line between the market town of Wallingford and the Great Western Railway main line at Wallingford Road in Oxfordshire. The railway, which opened in 1866, was originally planned to go a further 6 mi (9.7 km) to Watlington but this was never completed because of insufficient funds. Instead Watlington was reached by a 9 mi (14 km) line completed by the Watlington and Princes Risborough Railway company in 1872. After the Wallingford branch line opened, it ran regular passenger shuttle services to the GWR mainline for almost a century. It closed to passengers in 1959; the line escaped the Beeching Axe, remaining open for goods services until 1981.
