- Baltimore_and_Potomac_Tunnel abstract "The Baltimore and Potomac Tunnel (or B&P Tunnel) is a double track, masonry arch railroad tunnel beneath Baltimore, Maryland. It now serves Northeast Corridor rail service operated by Amtrak and MARC Train passenger railroads with an average of 135 trains per weekday traversing the tunnel.Whether considered a single 7,669-foot (2,338 m) bore punctuated by two short open cuts, or thought of as a tunnel with three sections, the facility is collectively referred to as the B&P Tunnel and constitutes the southern approach to Pennsylvania Station. It passes under the Baltimore neighborhoods of Bolton Hill, Madison Park and Upton, and is a bottleneck for rail traffic along the Northeast Corridor. A sharp curve at the south portal of the tunnel prevents southbound trains from exceeding 30 mph (48 km/h) while in the tunnel.An uphill, mile-long, 1.34 percent grade further constrains train performance.".
