This tunnel has been in continuous use since 1873, and its age is showing. Some estimates show the tunnels may not survive more than 10-to-15 more years. The tunnel is a bottleneck, allowing only two trains at a time. It has sharp curves which slow trains and, worst of all, constant drainage and leakage problems. If the B&P tunnel were to be condemned, it would become a nightmare for Maryland. MARC trains are frequently standing room only. Forcing these commuters onto the highway would overwhelm our roads, and the MARC Camden line most likely could not accommodate these extra riders.
