10751 is the headcode worn by the diesel railcar who failed at Barrow-in-Furness in the last story of Gordon the High-Speed Engine. As a result, Gordon worked his/her rail-tour train to Carlisle.
The DMU depicted is a BR class 127. The number "10751" is actually a headcode as opposed to its running number. The latter is unknown, but it would be in the range of 51591-51650.
The DMU is painted in the British Rail "Rail Blue" livery with yellow warning panels.
