37057 looks superb in the late afternoon light, as it passes Aslockton on 14 March 2016 with the 3Q01 08:34 Derby RTC to Derby RTC (via Skegness) Network Rail test train. With this being one of the few decent unobstructed viewpoints on the Grantham to Nottingham line, I was surprised to be the only photographer here. I was also lucky with the sun, as a little earlier it had been very hazy, but was back up to full strength by the time this was due. 37175 is the rear locomotive.
