Very excited to hear this mentioned in Tuesdays stream. Can't wait for more details on route and pack contents. During the 1960's and 70's these locomotives were the mainstay of the WR out of Paddington and sometimes even Waterloo. I am only speculating for now but am guessing that only the Class 52 will be included but it would be awesome to have some of the other hydraulic types which consisted of Classes 14, 22, 35, 41 ,42 and 43.
