"Incidentally we were also able to watch the swift raising of the pantograph at Swindon - just a second or two; but what surprised us was that when the 800s set off for London, with electric power operating, there was still a noticeable diesel rumble from behind the panels. Compared to Pendolinos and Class 90/91s, which are almost silent, the Hitachis sounded as if they still had some sort of minor generator operating. Again, any ideas would be welcome."
With kind regards, Brian.
Many thanks Brian for the picture and the question, can anybody out there supply the answers to his question please?
Many thanks Brian for turning out in bad weather.
