It’ll help pay for the Xmas Party? I’m old enough to remember when the G1’s were taken out of service. GCT offered them at £1 but the caveat was that they could not be structurally stressed following being lifted out of ’the pit’. The wooden construction helped their fast demise, and their uniqueness meant nobody could ever hope to put one into a Heritage setting. A damaged trailer coach was sawn in half and screwed to the wall at Buchanan Street following the 1980 refurbishment. Beamish and Critch indicated interest but I’ve no idea if they followed through.
The Metro-Cammell G2’s are stronger in construction, and at least be watertight above ground (the G1’s weren’t) so but I still find it odd to see these in a museum!
