I wonder if anybody can help with a question from England. I am a member of the Trust that owns and operates A4 Class Pacific Sir Nigel Gresley in the Uk. The designer of our locomotive, after which it was named, patented the Gresley Conjugated Valve Gear for 3 cylinder locomotives. The patent was licensed to ALCO in the 1920's.
We know the Gresley design was used on UP 9000 class 4-10-2. We also believe Alton and Southern 0-8-0 used the design and possible New Haven R3 & R3a. Can anybody help with information about these and other ALCO locomotives that may have used the Gresley arrangement?
Thanks!
