The following about 03125 is taken from “ERIE and D.L.&W. Wreck Trains” by Ronald R. Dukarm, c. 2009 Erie Lackawanna Historical Society, Inc.
Built in 1926 by Bucyrus Company, builder #4593. 160-ton capacity. Originally steam converted to diesel (date unknown, but several others were likewise converted between 1956 and 1958). To Erie Lackawanna in 1960. At some point, during EL years a pantograph was added to the boom to allow it to work in the electrified territory. To Conrail 45006 in 1976, then conveyed to NJDOT. Donated to URHS in 1995.
Original owned by the Lackawanna Railroad which later became the Erie Lackawanna Railroad. Pictured above with crane 03125. This was a Lackawanna TOFC flatcar which was constructed at Keyser Valley during the 1950’s. It was originally built, most likely in the 1920’s, as either an open hopper or a boxcar, as the DL&W used both when converting older surplus equipment to flatcars for piggyback service.
I have not yet been able to document either the Lackawanna number when it was in revenue service nor the EL number when converted to Maintenance of Way service. Although I can’t yet prove it, I believe 45519 is a Conrail or NJ Transit number as EL practice was to number MoW equipment with six digits, not five. Info submitted by Mike Dodge – ELHS member.
