Re: A list of square corner '37 AAR box cars

Jim and Barbara van Gaasbeek



The square-corned 4+5 Dreadnaught ends arrived yesterday in excellent condition –thanks.


I’ve recently read the 1937 AAR book – a bit of information overload – getting the info “through a firehouse”.  But it will be a superb reference book.  And thanks for the summary you’ve given in your E-Mail above.

Hello folks-

1936 to 1940 were the years that large numbers of square corner Drednaught end equipped '37 AAR box cars were built. As can be seen in the list below of these square corner end cars, there were many 10s of thousands of them built in both Canada and the US.


This list is from data in the recently released volume on 1937 AAR box cars by Pat Wider, continuing the fine series of Railroad Prototype Cyclopedias.

The RPC #35's roster data pages gives much detail, such as roof,brake and other details. Anyone viewing this post with questions about a particular Rail Road's details, PM me and I will answer those questions. I would encourage a purchase of the book, as it is a very well researched and detailed offering.


Southern, Union Pacific, Santa Fe, both Canadian transcons and the Southern Pacific were huge purchasers of this car design.


Wish everyone a safe and very well day.
