Another great pic from my Facebook feed... the caption reads:
”New Haven FL9 No. 2033 with train No. 10, the Murray Hill, arriving at New Haven, CT on July 21, 1968. A Roger Puta photo.
The EMD FL9 (New Haven Class EDER-5) was a dual-power electro-diesel locomotive, capable of diesel-electric operation and as an electric locomotive powered from a third rail. Sixty units were built between October 1956 and November 1960 by General Motors Electro-Motive Division for the New York, New Haven and Hartford Railroad”.
Those FL-9s look clean and have decent paint considering that the New Haven had been in bankruptcy for about 7 years when this photo supposedly was taken and only another 5 months or so remained until it was merged into Penn Central.
