It was dark, but 37s on a test train, not to be missed. 1Q16 Swansea – Derby. It was following close behind a stopping train, probably previous signals on amber so it was approaching slowly in case the Cradley signal was red. Once the driver got a clear view of the amber signal the 37s made a great noise as they accelerated through the station, only to shut off soon after passing through the station. Sounded great on the video!!
