The Emons-controlled Maryland and Pennsylvania Railroad acquired 19 miles (31 km) of a former PRR branch line between York and Hanover, Pennsylvania in the 1980s. In December 1999, Emons merged its M&P subsidiary with another area short-line, Yorkrail, forming the York Railway. In 2002, Genesee and Wyoming gained control of the 42-mile (68 km) York Railway, including the former M&P Railroad trackage between York–Hanover. The York Railway currently serves 40 online rail customers and connects with the Norfolk Southern and CSX railroads.
A small, 3-mile (5 km) fragment of the original railroad line still exists between Laurel and Muddy Creek Forks in York County, Pennsylvania, maintained by the Maryland and Pennsylvania Railroad Preservation Society. Founded by enthusiasts and former employees in 1986, the group has restored the Muddy Creek Forks station and also has a small collection of rolling stock there. The preserved Red Lion station is now a museum operated by the Red Lion Area Historical Society. Another section of the Ma and Pa's old right-of-way was converted in 1998 to a rail trail in Harford County, Maryland. Now 6 miles (10 km) long, the MA & PA Heritage Trail through Bel Air is used for hiking and biking.
In Baltimore, near Pennsylvania Station, Ma and Pa track remnants and the old roundhouse, freight shed, and yard shed are still extant. The Baltimore Streetcar Museum now operates in this area.
In York County, the Muddy Creek Bridge, Delta Trestle Bridge, and Scott Creek Bridge-North were added to the National Register of Historic Places in 1995.
