OGR Forum Moderator;
Please, if you would permit me to post the following:
I know and I'm sorry to rehash this Raymond Loewy 1947 Project 570 of P.RR. L.C.L. Merchandise Service 'PROPOSED' X40B 60ft. and X41B 50ft. box car schemes, but I want to answer Forum member Chris' 6 Apr. 2014 question and any other interested OGR Forum member, as to the design info. of said cars, as I came across the source info. to post here and now, putting this subject to rest.
As, far as I can find out, I BELIEVE, these cars were not prototypically produced(Unless I'm wrong).
The old post of the color photos. were evidently Loewy's rendition designs.
I obtained the info. from; "The Keystone" magazine of Spring, 1991, Copyright 1991, USPS 128-670, ISSN 0744-4036, Volume 24, Number 1, bottom of page 48, an 'Official Publication of the P. RR. Technical and Historical Society.
Respectfully,
Thank You,
Ralph
