Re: MTY's breaking the N-G distribution model

Almost any large rail yard will have strings of home road cars. They
could be (1) awaiting repairs or (2) awaiting assignment. They park them
together to keep them away from cars in transit. They are NOT a consist.

I found another photo on Shorpy I was not aware of:

Barstow, CA, 1943, ATSF yard.

Notice the string of ATSF XM's to the left of the hoppers - every box car is ATSF. In addition to that specific string, there is a real shortage of foreign road cars in this picture. Did Barstow have an MT yard?

I think we have all reached general agreement that the N-G distribution model for box cars is well supported by the data, at least for WWII.

I previously postulated that while the N-G model is good for the car distribution averages on trunk lines, I think this photo helps support the concept that it may not be accurate for individual trains with significant MT consists.

Even though this is a yard, I find it hard to believe that a yard crew would split up that string of ATSF box cars just to intersperse other RR box cars in it when it left (and it may have arrived as a consist.) I also suspect that the string must have been MTs - hard to believe a consist of loads would be 100% ATSF box cars. Loads no, MTs yes.
