The New Frederick Douglass Tunnel – Improving Amtrak Services

Posted August 1, 2023, Length: 19:20

The 150-year-old Baltimore and Potomac Tunnel, Amtrak’s oldest, carries traffic for Amtrak, the Maryland Area Rail Commuter (MARC) Service, as well as Norfolk Southern freight operations. This tunnel is a major bottleneck for Northeast corridor rail traffic, and Amtrak is rebuilding it and adding a new, passenger-only tunnel named after abolitionist Frederick Douglass.

In this podcast we learn about this large program from Mark Milton, Senior Director, Capital Delivery for Amtrak, who is managing final design and construction for the overall program. Mark’s a civil engineer with many years of experience in design.
