Re: rock island wreck photo
Andy is right that all the SP cars with wide seams were built in
1946. This included all of the B-50-24/BE-50-24 class (500 cars)
and many cars of the B-50-25 class (1,100 cars which includes
350 cars for T&NO).
The doors on the SP 10'0" cars have 5/5/5 patterns while the 5/6/5
pattern is found on 10'6" cars.

The interim improved Youngstown doors were around a very short time. The most
famous, the SP "Overnight" cars, and the Santa Fe cars were built very close
together. When Youngstown brought out their "Improved Youngstown Steel Door",
The first examples were of the 6/6/5 "Upside-down" count, a feature that also
seemed to only last less than a year, though with quite a few users. I have seen
no other examples of the 10-0 IH Interim IYD, only for SP. The 5/6/5 Interim IYD
door was used by the Santa Fe (Bx-44), and now, I see, the Rock Island. All were
pre-1947.
Doors can be an important feature on identifying eras, look at the panel counts
and spacing for the Superior doors, very year specific.

Interesting comments about the boxcars and the door on the near car. I take it
Andy that when you say that the door dates the construction to 1946, that means
1946 or later? Or were those doors in production so briefly that they were only
used on cars delivered in 1946?
