Since I don't start my new job until the 30th both my wife and I were looking after my young son today. He was watching some trains on a TV programme so we decided to take him to NRM at York to see some really cool ones for real.
Anyway, I was looking at the Deltic there and got to thinking about the engine: is the deltic type still used in any applications today; marine, rail, generators or anything? If not, why?
