Makes sense. Cheers RhysGiven that 70813 had a mixed consist on Saturday of TEA tanks and 3 IWA log wagons coming down from Carlisle, I can only assume the 3 IWA wagons were left at Barnetby and 813 took the TEA tanks to Immingham. Then returned to Barnetby light engine and then took the 3 IWA wagons to Doncaster.
