37688 Kingmoor TMD passes Chilson in the pouring rain on 24 March 2016 with the late running 1Z03 09:37 Bristol Temple Meads to Derby RTC Network Rail test train. This had lost its original path over the Cotswold Line, having arrived at Oxford an hour early, but then departed an hour late! 37601 Class 37-'Fifty' is on the rear of the train.
