With the cold weather I have had some quality train time which includes reading some new materials and making a few repairs. First I came across Penn Central Trains NE97 and NE 74 on page 164 in the book Penn Central Power by Robert J. Yanosey. An excellent book that I have read and referenced constantly.
In summary in 1973 the Penn Central wanted to eliminate much of their Maybrook Yard operations that they inherited when the New Haven Railroad was merged into PC in 1969. The New Haven and Erie Lackawanna interchanged a large amount of New England traffic at Maybrook. As traffic shrunk the EL sought relief and PC came up with a plan which eliminated Maybrook's terminal facilities by establishing a pair of run through trains, NE-97 and NE-74. The trains ran to and from the EL yard at Port Jervis, New York and the PC yard at Cedar Hill, New Haven CT. The trains appear to be powered by GE units.
Wanting to replicate this train on the New York Central Train Layout I checked the train rosters and found that the only Erie Lackawanna units my son has are EMDs and one F7A-F7B set in need of repairs and upgrades. So.... some modelers license and repairs and PC trains NE-97 and NE-74 are running on the layout.
