To clarify, I asked this two years ago. I am wanting to model US Army S-100. An 0-6-0 with tender that was used into the 1960s at Fort Eustis. I want to know if the 0-6-0 boiler and/or cab can be swapped out with the 2-6-0 boiler and/or cab. Any help from Bachmann or anyone who has completed this swap would be appreciated.
