would there be merit in doing this car as a flat pack in order that people can choose to assemble it with PS1 ends? or whatever would make it more 'generic'? (my knowledge of 50' boxcars is very limited.)

I'd have to look at some photos but off hand I think yes... make PS-1 ends and a different roof and it could work. But I'm not sure off-hand, as I said. I've never really studied the 50' PS-1 in-depth... just a couple years too late for me, though I can use the 40'.

What you are really suggesting is a "family" of 10ft-6in 50ft cars, including either improved Dreadnaught or Pullman-Standard ends.

1) 50ft - DD + improved Dreadnaught (the A-50-17)
2) 50ft - DD + Pullman-Standard (generic 50ft PS-1 DD)
3) 50ft - SD + improved Dreadnaught (the B-50-30)
4) 50ft - SD + Pullman-Standard (generic 50ft PS-1)

You could keep going down this path with the 40ft cars...

The flat-kit vs one-piece is really just a production/casting issue one you have the masters.

... or in the alternative, maybe there were other RRs who had 50' boxcars with 1/3/4 ends, diagonal pressed roofs and other features similar to the A-50-17? thinking out loud, total ignorance of the topic here ...

... will have a trawl of the RMJ on trainlife because there's good articles there on various series of boxcars.

(was just going to ask Richard B what he thought, and he beat me to it ...)

NOTE: The Espee A-50-17 (double door) and similar B-50-30 (single door) are NOT PS-1s of any flavor...
They are kit-built cars from an assortment of industry-standard parts, and assembled at the SP Sacramento Shops.

A key spotting difference is the 1-3/4 (top-down) Improved Dreadnaught ends instead of the parallel rib PS ends, which were only used by the Espee on class B-50-37....


bit confused. isn't an improved dreadnaught 4/4?

i can find a number refs to postwar 1/3/4 ends on 40' cars, but they are 10' IH , and this is 10'6" IH, isn't it?

Good Point:
C&O for sure... and the Espee shared at least one order with them.
C&O-6099 XM-50ft-DD_VancouverBC-16Oct1948_WEFrost-CVA28708.jpg
C&O 50ft DD with 1-3/4 end

A quick look shows that GARX had some 50ft SD cars with the 1-3/4 ends as well...
GAEX-108020 XME-50ft_VancouverBC-Mar1951_WEFrost-CVA28740.jpg
GAEX 50ft SD with 1-3/4 end

For even wider coverage on the 10ft-6in cars (both 40ft and 50ft)...
you would also want Dreadnaught 5-5 and improved Dreadnaught 4-4 ends.

I Think? There has been some dispute on this issue...

The more common improved Dreadnaught 4/4 does not use the slim rib at the top... all ribs are identical.

i was wrong. the 1/3/4 end 40' boxcars seem to have been 10'6" ... there are articles listed here

http://www.trainlife.com/magazines/page ... 00-page-56

... there were others of 10' IH built for SP, NYC, B&O, CNJ and a few others. i think the end is called 'interim improved dreadnaught' ?

At a guess, I wonder if the Rock Island cars may be these:

http://trainlife.com/magazines/pages/44 ... 95-page-24

Sunshine did kits for 2629800-262999 in HO. though the recessed fishbelly sill gives a passing resemblance to the SP cars, a number of details differ ; narrower side panels, 5 and 7 vs 4 and 6 respectively on the SP car, 5/5 dreadnaught ends and an 'improved' steel roof. with those details it's no surprise to find the RI cars were built in 1941.

tl;dr the Improved Dreadnaught situation is just as complex as the regular Dreadnaught situation, varying not just in rib count but rib shapes and... hmm. Maybe I should do a post on the various boxcar ends like I did for some boxcars?
