50531 being partnered with 50479 and returned to working order at the Cambrian Railway (Oswestry), moving shortly afterwards to the Telford Steam Railway in 1999.
Between 1999 and 2004, 50531 operated on the short line at Telford with 50479, being withdrawn occationally for rolling restoration and repair work to be undertaken to keep the vehicle in reasonable condition.
In 2004, new fire safety regulations caused the railway to withdraw 50531 from service, and as the original group which was set up to look after the vehicle has disbanded, the work to modify 50531 was never undertaken. The vehicle has been in store since. 50531 remains on long term loan to the Telford Steam Railway and it is hoped will provide passenger accommodation again in the future.
