The Morristown and Erie Railway is a freight short line railroad based in Morristown, New Jersey. It operates freight rail service five days a week in Morris County, New Jersey and surrounding areas. It owns its main line between Morristown and Roseland and maintains and operates three other lines in Morris County (Dover & Rockaway Branch, Chester Branch and High Bridge Branch) under a $1-a-year contract with the county.
Freight is interchanged with Norfolk Southern at Lake Junction (the north end of the Chester Branch).The Morristown & Erie Railway (M&E) has in recent years expanded its system, now operating private trackage at the Bayway Refinery in Linden.
The M&E is working with Union County to revive freight service along the northern portion of the former Rahway Valley Railroad trackage between Summit and Cranford. Inclusion of the former Rahway Valley Railroad trackage in the M&E system would allow the M&E to access its Bayway Refinery operations via its own track, and to interchange with the recently reactivated Staten Island Railway freight connection to New Jersey.
