Long Island Railroad No. 1556

Long Island Rail Road No. 1556 is an ALCO RS-3 diesel locomotive built by the American Locomotive Company (ALCO) for the Long Island Rail Road of New York in 1955. This RS3 was used in both passenger and freight service across Long Island until 1978. 
The 1556 was equipped with multiple unit speed controls. Original equipment also included a steam generator for heating steam-heated passenger cars which was removed in later years after the passenger cars were modified to no longer require steam for heating purposes. No. 1556 was also one of the locomotives that participated in Long Island's official "End of Steam" ceremonies on October 8, 1955.
It was sold to the Gettysburg tourist railroad in Pennsylvania and served as the No. 56 of their fleet from 1978 to 1983. The Riverhead Railroad Museum of Long Island purchased No. 1556 in the spring of 1986 and brought her back to Long Island where it currently remains on static display.
