I still think a "Leader" would be good. It was an experimental design. Bullied could have had more time to develop it or at least Riddles could have had a good crack at it. A Southern "W" class could be a project as there were a lot of K,N and N15 parts used. I know people would say there are enough spams including rebuilds (Lucky I guess that so many were saved. IMHO)There are Garretts available 1 in Glasgow and 1 in Manchester.

"Make loco's not war", could be the battle cry of the 2010's.
