I think sectioning and removing one rib from Branchlne's 7' wide door on their 10'-6" AAR car is the best way. James

Hi guys,

I just acquired a Sunshine kit for a CRP XM-4, but it was for the Superior door version. I want to make this car the Youngstown door version as there were more than twice as many. Does anyone know if there's a source for the right Youngstown door? If not I may have to splice.

Thanks,
Phil Lee

That's a 5-6-5 Youngstown door yes? Dan Hall made a 6 foot 5-6-5 door (#614) that may work
with some vertical splices and then resin molds and casting. Many prototype cars had 5-6-5 but I
don't know how many of those had 7 foot doors.

Thanks guys. This is a 5-6-5 door as in the below photo.

Tim, I'm not sure about 10'6 IH, but after looking a bit, afaik the CNJ cars might be the only prototype 10' IH.cars with that style of Youngstown door.

The most common of improved Youngstown steel doors was the 5/6/6, used in multible widths for nominal 10'6" height box cars. Two common versions of the YSD was as a 5/6/5 and not as well used, the 4/6/6.

For a 7' wide 5/6/5 YSD, I would not work with the Southwest Scale Models 6' wide version, as that would involve two splice lines-one on each side of the center. A much easier route would be to use a Branchline (Now Atlas) 7' 5/6/6 YSD and simply cuting one panel on the bottom section. I would remove the panel just below the bottom horizontal splice line. Whenever I can, I like to make these changes right on the rib, where the witness line will be essentially unobserved, just like you would do on Stanray Murphy panel roofs.

Tim/anyone,
  I'm not challenging the differences - but I have a question ...

  Why would a railroad order/use a 5/6/6 -vs- a 5/6/5 -vs- a 4/6/6 ... etc.?  Other
than a spotting freature why did Youngstown make different configuration for 
a "nominal 10'6" height door?  
  Were these actually made so they would fit 'slight' (?) differences in height?
Done at different times ("evolving technology")?  Some other reason?

  And, for that matter, was there a significant difference between the Youngstown
doors and some other makers?

  Or was it all about the cost ... at a point in time?

Pure, uninformed speculation: Could it also have to do with the thickness of the steel used in the various door panels, similar to what was done with car ends? For example, could the bottom panel of the door been of a heavier gauge steel, with the different panel heights depending on how high the car owner wanted the heavier gauge steel to extend?

Just my thinking. 

Yeah but... we're not talking about the size of the door here, but rather the relative size of the panels that make up the door. It's easy to see why the stamped steel ends on the USRA cars were three panels; the cars were five inches taller than what came before, and likely two panels would exceed the size of the available stamping presses, especially on short notice. But these doors used different combinations of panels at different times. I suspect the answer lies in what other doors the three panels were also used in, and which panel (top, middle, or bottom) was easiest to build a tool for, considering the low production anticipated after the AAR standard went to 10'-6" IH.
