Athearn RTR 73743 HO Scale EMD SD40 Penn Central PC 6257 DCC & Sound

Built in late 1970 and early 1971, this group of SD40s was delivered new to the PC, but was similar to the units inherited from the Pennsy. As some of the newest and most reliable units on the roster, they were used in almost any type of service, but were most frequently found on the mountainous territory between Pittsburgh and Harrisburg, the latter being their assigned maintenance base.
