37421 passes Combe on 2 November 2016 with the 1Z78 06:45 Tyseley to Bristol Temple Meads Network Rail test train. Sometimes you can almost have too much of a good thing. Full sun was guaranteed, which has accentuated the autumn colours, both of the leaves and the lichen encrusted branches of the hedge. However, with a yellow train, led by an orange and yellow locomotive, the result is almost too much of one colour. It would have been better if the blue 37025 Inverness TMD was leading, rather than being on the rear!
