There is a significant amount of letters, circulars and correspondence about car shortages, car orders and new car production numbers covering the period 1944 to about 1950 in the SRHA archives. Questionnaires were sent out by the AAR then the responses were accumulated and used to produce various reports. Individual railroads were cited as not providing their “fair share” of equipment. Surprisingly (to me), the NYC was criticized for trapping foreign road cars for use on its lines. Historically, the Southern always received rather than paid when car hire charges were settled.

There is too much raw data to distribute but the subject may make for an interesting presentation at CCB 2016 if people think there is enough interest in the topic.
