Rutherglen Permanent Way depot is located north of Rutherglen station on the West Coast Main Line. Various different track machines, snow blowers and very occasionally, the odd locomotive can be seen here.
The PW depot is located near to where the tracks from Whifflet join and can be seen on the right hand side when heading into Glasgow.
When passing on the train on Saturday, I got a couple of photos of the various track machines stabled there.
