~Recent arrival at the NYMR, 31466, arriving at Goathland from Pickering. The locomotive had a horn fault, constantly emanating a single tone from the front of the locomotive.
Having come off the train at Grosmont, 31466 was sent to the shed. Various noises indicated that the horn valve was being twiddled with, but not enough to quickly clear the problem.
Two pictures of 37264, which was on-shed at Grosmont for exam.
D7628 (25278) was spare at Grosmont, and came off the shed to substitute for 31466.
