Reply to comment by md9918 in Thanks to everyone that introduced me to using the MARC train for my DC work commute! by cherrychampagnetoast

Amtrak Regional goes up to 125, Acela up to 135 in Maryland. Acela is capable of 150, but the catenary system is an old design that prevents this. But Amtrak does have a project planned to upgrade the catenary, and the new Avelia trainsets can go 165! So we may see even higher speeds in the near future
