107 340 on a Cumbernauld to Springburn service has just passed Cardowan Signal Box. The connection into Cardowan Colliery is just visible beyond the Signal Box. Closest is a Class 107 DMCL, the other two vehicles are 101s. As the DMBS is a 101 the other end probably has a different set number. Spannerman37025.
Do you have any images of the set you can add?
