Dominic Mazoch posted:So the ATSF had to put into the FT units converted into passenger service items like signal lines, steam generators, and higher gearing in the trucks?
Yes.
Did they do it themselves,
Yes.
or sent them back to EMD?
No.
And did most of the passenger equipment stay onboard when they went back to freight service?
Probably not. The steam generators would surely have been removed for replacements/parts for other passenger units.
