37606 arrives at Garelochhead on 23 July 1999 with the 7D54 11:58 Fort William to Coatbridge aluminium ingots. As I had been listening on the scanner for its approach, I knew exactly what would happen next. The driver had reported that the RETB token apparatus in the leading cab was not working, and had gone to the rear cab to use the equipment there during the token exchange at Tarbet. As I expected, exactly the same procedure was about to take place here.
