The TVR class O1 was a series of tank locomotives with a C1 'n2t (0-6-2T) wheel arrangement designed by Tom Hurry Riches . They ran on the Taff Vale Railway (TVR) from 1894 and were retired by 1931. Locomotive No. 28 is the only surviving standard gauge locomotive built in Wales.

history

The locomotives were built by Kitson & Co. and the Cardiff West Yard Locomotive Works of the Taff Vale Railway. At TVR, the three-couplers were used in front of freight trains that brought coal and ore from the mines to the port. After the Railways Act 1921 brought about the Great Western Railway (GWR), the TVR was integrated into the new railway company and the locomotives of the O1 series were taken over by the GWR, which they retired between 1925 and 1931.

The following table shows the numbering of the vehicles:

Locomotive 28

Operational use

The locomotive with TVR road number 28 was the last standard gauge locomotive built in Wales . At TVR it was used in front of ore and coal trains from the mines to the port. When it was taken over by the Great Western Railway in 1922, it had covered 483,189 miles. In 1923 she received a new boiler from the West Yard Works during a major overhaul.

After it was taken over into the GWR stock, the locomotive was given the new road number 450, and it was provided with a cover over the safety valve, as was customary on GWR locomotives. The external appearance remained unchanged. The locomotive was parked on October 30, 1926 but was in good condition and was sold to the government in 1927 for service on the Woolmer Military Instructional Railway, later called the Longmoor Military Railway . It was named after the general of Khartoum Gordon and was kept in pristine condition in Hampshire , being used for relatively light tasks compared to the TVR times.

When the Second World War broke out , the locomotive was renumbered WD 205, later WD 70205, but was then no longer needed and stored. In 1947 it was sold to the National Coal Board (NCB) and used on the Hetton colliery railway . Here it was given the company number 67, but kept the Gordon nameplates when it was used again for heavy duty in the coal fields. In 1955 it was completely overhauled, which resulted in small changes to the appearance, in 1959 the boiler had to be repaired, in 1960 the locomotive was decommissioned.

conservation

After the NCB was asked to rescue the locomotive, it was successfully donated to British Railways for conservation in 1962 , so it became part of the National Collection , the British state's collection of historic railway vehicles. The original intention was to restore the last standard gauge locomotive built in Wales to its original TVR condition at the Caerphilly Locomotive Works . However, the project could not be implemented because the location was closed. The number 28 was the last locomotive to leave the site and was posted first in Swindon , then in London .

In 1966 it was returned to Caerphilly and given to the National Museum of Wales for safekeeping by the National Railway Museum (NRM) in York , which houses part of the National Collection . In the late 1960s and early 1970s, the locomotive was refurbished by the Caerphilly Railway Society and was able to operate on the association's small site for about seven years from 1983 until the boiler deadline had expired. While she was waiting for the boiler test, the site was closed . The locomotive was then loaned to the Dean Forest Railway for over a decade , which dismantled it for a thorough refurbishment. However, the work was stopped after broken springs were discovered.

The NRM transferred the locomotive to the Llangollen Railway in 2013 , where it was reassembled. Thanks to a three-way partnership between the NRM, the Llangollen Railway and the Gwili Railway , the external refurbishment of No. 28 was tackled in 2013. The goal was to return the locomotive to its original condition. In 2014 it went on permanent loan to the Gwili Railway , where it came under the care of the Gwili Vintage Carriages Group . The locomotive was on display with the only standard gauge railroad car built in Wales. The agreement reached, however, expired in February 2020.

On October 1, 2019, the NRM and the Welsh Railways Trust , which emerged from the Gwili Vintage Carriages Group , announced a three-year agreement with which the locomotive is to be reconditioned for operation. The project is expected to cost £ 160,000 , or € 178,000, of which 18,000 will come from the Association for Industrial Archeology . The money will be used to refurbish the locomotive's running gear and engine , which still contains original parts from the Taff Vale Railway. The locomotive will be refurbished at the Gwili Railway , where it will then also be used.
