This is speculation, but i wonder if icing up was less of a problem with bottom operated couplers. Steve

Mike, AAR interchange rules required rotary coupler operating levers on cars built new or rebuilt effective 8/1/33. That ended new applications of Carmer levers. I don't know of any interchange ban,

Thank you Bruce! This is pretty much what I suspected. It would be interesting to see if any PRR documentation adds to this understanding. Clearly the Carmer lasted right up near (if not to) the

Mike, My general impression of the transition in the coupler mechanism of the X29 was that the Carmer uncoupling device was considered to be less safe that the bottom-operated rod style. While not

I am getting confused here, Tim---- I do not follow the relevancy of your reference to a 1925 SP tank car. All my questions were intended to address the Pennsy's use of the Carmer on their X29

Fenton, thanks for that. Allan, I dug that out of my files, yay! Anyone know why these aren’t among the list of 1937 AAR Modified Design? Is it because of the double doors? To complicate matters,

Thanks gang. Steve, thanks for the awesome link! Tim, I think you are right, probably start with a 1937 modified 10’6” IH and convert to double door. What do we call these ends, 4.75 / 5 ends? I

Mike Was it just a matter of a rapid change from top-operated to the bottom-operated couplers for NEW freight cars, and then the gradual retirement (or

Fair enough. I have 348 scans of cars rebuilt in the 1950's :-) I just meant I don't think rebuilding has ever ceased. Obviously there are ups and downs. Tim

Some of those cars were rebuilt - when less than a year old - with extended height. Here are a couple of Ted's scans from Ebay. Tim O' --

Best place to start may be 10-6 car with 5/5 ends and 6 foot door like the Intermountain kit. Or even the ancient ATHEARN blue box car, which is just a tad too short for a 10-6

Steve, I think you have caught me. For some reason I have conflated the two names and I don't have any handy reference to further my understanding. I did however check in with my ERIE diagrams.
