Great Western train naming honour
The Great Western Society has had a train named after it by operating company First Great Western.
The nameplate's unveiling took place at Didcot Railway Centre, in Oxfordshire, at 12:00 BST on Saturday.
The naming was in honour of its half century of work to preserve railways in the UK.
Chairman Richard Croucher said: "We look forward to seeing it traverse the old Great Western Railway territory over the forthcoming years."
The nameplate on the power car reads: "Great Western Society 1961 - 2011, Didcot Railway Centre".
High speed trains travel up to 125 mph (201 km/h) and have a power car at each end.
The Great Western Railway was the route through Didcot from Bristol to London designed by Isambard Kingdom Brunel and completed in 1841.
