Having arrived at Cumbernauld we had a decision to make.

Did we wait for a couple of a freights heading this way or head back towards Glasgow and then on to Ayr for what would be a pretty late shower and a meal? We decided to head straight back so, after it had gone into a refuge siding and reversed back into the station we took 318259 working the 17.25 to Dumbarton Central as far as Stepps station.
