Re: What was a USATC S-155?

I have always heard the claim that there was a stockpile of US Military 42" gage equipment that was built for the expected invasion of Japan, and that most of this equipment was declared surplus at the end of the war and sold off. But I have never seen a comprehensive list as to which locomotives or rolling stock built in the US for the government was assigned to US locations, foreign locations (and those later transferred to those countries), lost at sea, or declared surplus and sold after the war (possibly as new having never been used).

Were the Newfie engines built specifically for them, or part of the war surplus? Some of the later 42" gage engines in Central America for United Fruit or Standard Fruit may have either been war surplus or post war copies. Sometimes locomotive can mislead you because they show the date shipped or sold, not the date actually built. So engines built for stock or a cancelled/returned order might have misleading dates on them.
