I haven't split it yet. I cut this flat, then pop it in half, put a draft angle on the inside to get the peak. These are just the parts so far.

should this be an A-50-17 boxcar? I can find no information on "B-50-17" which surprises me as I know that one or two people, or possibly even as many as three, model the SP ...

Up until the mid-50s, SP designated Auto Box cars with "A" and other Boxcars with "B". They later changed it so that all Boxcars, regardless of use were "B" designated cars.

That is a very good looking start to a boxcar. I really need to learn how to scratchbuild rolling stock like that.

There is little data on 'B-50-17' but it appears A-50-17 has the right number range, that is 190000 and onwards, and just noticed ... the diagram Joe links to says it's an A-50-17.

Would like to dig away and find other owners of this type, in particular I'll sniff around the Rock Island lists and see if there are mentions of A-50-17 (or the similar A-50-18s) on the Rock.

Sorry about the confusion...the model started life as an A 50, but as was mentioned above, much later the designation was changed to "B". I'll check my data bases at work as well and see if there is something simular.

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....

Sort of....
AFAIK - The Espee differentiated between A- (Auto Box) and B- (Box) cars for their entire existence in the original number scheme... and didn't do any BIG renumbering/re-classifications (if at all...) until post-1965

I don't think the SP ever bothered to single-door any older DD Auto Boxes, as some roads did.
