43015 passes Compton Beauchamp on 16 May 1988 with the 1C68 18:05 Paddington to Taunton service. Note the lack of any exhaust or heat haze above the leading power car. This is because it was not working, and the train was being pushed from the rear by the back power car. I thought something was amiss when I realised that it wasn't approaching at the usual 125mph. I have only seen HSTs running on a single power car on a few occasions, and mostly it seemed to be the rear power car that had shut down. No doubt nowadays this train would just have been cancelled!
