56311 heads 6Z48, the 13:15 loaded spoil train from Thorney Mill to Calvert, past the old station platform at Calvert as it heads up the "main" line southwards. Once it had passed the unloading gantry area (where 66951 is standing with 6M23, the empty Cricklewood "binliner"), the loco uncoupled and began a run-round move which would have brought the engine past here again on the far right track. This move was then changed and the loco re-coupled to the train and headed further south before propelling back onto teh unloading siding. 17:06, Monday 3rd June 2013. Digital Image No. GMPI15948.
