This 50? flat car with fishbelly sides and side mount brakewheel is box car red with white lettering, has a white oval NYC logo and runs on black Bettendorf trucks. This 50? flat car was built in January of 1950 by the General American Transportation Corporation in Chicago, Illinois. The NYC system was the largest of the Eastern Trunk systems from the standpoint of mileage, and second only to the Pennsylvania in revenue. It served most of the industrial part of the country and its freight tonnage was exceeded only by the coal carrying railroads. NYC and Pennsylvania merged in 1967 to form the Penn Central.
