Some of these Jim Gillies could answer perhaps?
On the 17th May:
At Shettleston depot, viewed from the train, there were 7 or 8 baskets parked outside, most were Manitous, but there was one blue and yellow Genie there too.
At Cowlairs NR depot there was a Fuso, a Unimog U400 and another van or lorry type vehicle, as well as a Kubota RTV900.
Slightly further down there were four Story Manitous, the only one I managed was Mewp06.
There were four more of them at Croy.
On the 22nd:
There were 2 SBRail track machines in Inverkeithing Yard, one was DR77001, the other I can't work out. It was a 'longer' style, like 73803 or 73941 for instance.
On the 23rd:
I saw Morgan Sindall 942088 just North of Berwick Upon Tweed. Just South of the station there was another identical one.
Near York yards was a McCulloch TRT, I think it may have been 23?
At Carlton on Trent (approx) there were 2 SPL baskets
At Barkston South Junction there was a Quattro excavator and Mecalac
Finally, there were two TRTs near to Finsbury Park
If anyone knows any of the above it would be greatly appreciated, especially those in Scotland.
