70 minutes early was translated into 50 minutes late by the time the Pathfinder Tours 1Z58 17:43 York to Bristol Temple Meads 'Twilight Grids' railtour departed York on 31 March 2004, due to 56078 & 56115 not talking to each other. The multiple working problem was resolved by running the locos around, so it was 56115 Barry Needham that was leading classmate 56078 as the train hammered through Church Fenton in failing light.
