On 6 March 1926 GWR 4786 Full Third was completed at Swindon, one of 279 such carriages built between 1925 and 1929.
4786 is a Collett designed Bow-Ended 57ft full third coach, built to seat 64 passengers in eight compartments, with a side corridor and a toilet cubicle at each end. Having worked main line long distance services, and then cross country, it was withdrawn in 1960 and modified for S&T use at Shrewsbury. SVRH bought it in 1986 from the Coleham Depot.
Now owned by GW(SVR)A it is being returned to the fully lined GW livery to join the 1920s GW set.
