I couldn't resist this little piece from a railway society website:-
class 37, number 37097 was named "Old Fettercairn" by David Doig, the manager of Fettercairn distillery. The locomotive was named in recognition of a donation kindly given by the distillery towards repairs to the class 37's engine. Steve Moir, chairman of the Caledonian Railway's Diesel Group presented Mr Doig with a framed print of the locomotive and visitors were invited to have a dram of whisky to toast the locomotive.

I like the way in which the piper's outfit is colour co-ordinated with the railway locomotive.
