Did Maine Central have PS-5s? I can't find anything for the Maine Central except for the 12100-12122 series of 52ft 6in gondolas. These cars have dimensions that look OK, but my 4-74 ORER indicates that the series is new or that the number of cars has increased. They don't appear in my 10-70 ORER. I don't have any ORER issues between 10-70 and 4-74. 1974 seems too late as a built date. Were these PS-5s? Did MEC buy them as used cars?
Larry, I have a photo of MEC 12019 and it was a second-hand war emergency composite mill gon with the original wood sheathing replaced by steel. Appears to be a former NYC car.
