I too would like to see the Wabash Hudson, but... like most other passenger engines, I think the project would draw a better demand if a complementing passenger train was also introduced. Even if the passenger cars came at a later date.
I now have two sets of beautiful E6 passenger units waiting for something to pull. Not ready to sell, but I won't wait forever. No more passenger units (steam or diesel) unless a rake of cars is available or will be available.
