I’ve been absorbing info for over 30 years now (49 years old) and I still consider myself a novice. Lol. Brian J. Carlson P.E.

Dang. I think you’re correct. I was basing it on the first truck. Looked longer than 50’. Brian J. Carlson

New roof by the 50’s. Brian J. Carlson

Scott Branchline / Atlas 40 ft boxcar. I’ll also not me these are B&O cars and the OP asked about PRR and NYC. Brian J. Carlson

Bowser. To me they have shortcomings in the underframe and cast on details but with a little work they are acceptable. Now a double door X31a I would use Rapido but X31, X31b, X31c, X31d, and x31f, yo

Plastic. Maybe, depending on your opinion of the bowser PRR x31, x32, and x33 family of cars. Brian J. Carlson

Yep that’s an MDC. Brian J. Carlson

Branchline didn’t do 37 ft reefers in their line. Is this an earlier Branchline custom painted model (mdc) and not Blueprint. Can you share a pic? Brian J. Carlson

Yes. The 7’ is the issue. The Dan Hall 10 ft doors are Out of stock. http://www.southwestscale.com/Freight-Car-Details_c3.htm Brian J. Carlson

The panel count is wrong for CNJ doors. Sectioning won’t work. Brian J. Carlson

That gon didn’t exist before 1960, so who knows it’s in the future. Brian J. Carlson

CNJ 12136 would be a 36 ft car. Only left on the roster in 1950. Brian J. Carlson, P.E. Cheektowaga NY

Agree with Resin. The NKPHTS had rider cars cast in resin. We sold at least 75. Maybe 100? Several years have passed I can’t recall if I did 75 or 100 overall. Brian J. Carlson

Remember to upgrade to AB brakes too if doing the green and yellow cars. Brian J. Carlson

Someone on Bowser’s marketing, web, or art staff got into the edibles. These https://www.bowser-trains.com/new/H34.html Are just the standard Bowser ACF 1958 cubic foot covered hoppers gussied up a li

You glue the decal down? When I add decals to otherwise completed models I lay down Microscale gloss using a small brush in the area of the decal. I let that dry them decal like normal. Reweigh decals

Based on ORER data 3 Pennsy X26 made 1963 in revenue series. However, I’d take that with a grain of salt. They probably weren’t actually in service, just stored not yet white-lined. Face it, unmodifie

You can’t find any in the 60’s or later because they just didn’t last that long unmodified. TH&B cars were long lived into the 50’s but they were an exception. Brian J. Carlson

Thanks Chris. I absentmindedly forgot about the RPC. I’m pondering if I can create a M-15N from the F&C M—15k with a new underframe. I fear the resin thickness might be an issue Brian J. Carlson
