A Passenger Equipment Question

[NW Mailing List]

Thanks for explaining that. I wasn't familiar with those abbreviations. Since all my passenger equipment is 1:87 scale it never popped up before.

Mr. HuberDeerCreek -




"COT&S" is "Cleaned Oiled Tested and Stencilled."




"IDT"  is "In Date Test."




"UC" was the standard triple valve on passenger equipment beginning in the 1890s.  I saw some of it still in service in the 1990s, and one of the air brake shops in Pittsburgh was still working on UC equipment as of the time I retired 8 years ago.  If they didn't weigh about 500 pounds a piece, I would have one in my basement.  The UC valves allow for a graduated release, which freight triple valves do not.




Not stuff you need to worry about unless the railroad cars you push around are 1-to-1 scale.
