The driver of 47277 leans out of his cab to check that all is well, as he pulls out of the up loop at Highworth Junction, Swindon, on 26 October 1992 with what is presumably the late running 6A15 23.55 Waterston to Colnbrook aviation fuel tanks. As this was booked at Swindon at 05:34, and this train waited in the loop for some time, there is a possibility it is a 6Zxx working to who knows where. Confirmation anyone?
