[2] The company was created in 1999 through a consolidation of Yorkrail, Inc. (reporting mark YKR) and the Maryland and Pennsylvania Railroad (M&P), both owned by the Emons Railroad Group, and it immediately sold the property thus acquired to limited liability lessor subsidiaries with the same names (Yorkrail, LLC and Maryland and Pennsylvania Railroad Company, LLC).

The M&P's current main line is an ex-Pennsylvania Railroad line that it acquired from the Penn Central Transportation Company in 1976, beginning at a connection with the Norfolk Southern Railway in York and running to a CSX connection at Hanover.

The Yorkrail line, running from a junction with the M&P in York to a CSX connection at Porters Sideling, PA, was opened in 1893 by the Baltimore and Harrisburg Railway (Eastern Extension), a predecessor of the Western Maryland Railway, and sold by CSX Transportation to Yorkrail in 1989.

The railroad also operates ex-CSX EMD GP16 diesels #1600, 1602, 1604 and 1606 as well as a pair of LTEX GP15-1s numbered 1414 and 1444.

The 1502 and 1504 were parked for several years in a deadline between Hokes Mill Road (Route 182) and South Sumner Street in York, Pennsylvania, along with GP9 1754.
