The Penn Line uses diesel as well as electric locomotives for powering trains.
Most electric and rush hour diesel trains are 6-8 cars long, and are primarily made up of Kawasaki bi-levels.
During the day, shorter 4-6 car MultiLevels or single level diesel trains from the Brunswick and Camden lines are used on the Penn Line.
For the spring and summer months, weekend Penn Line trains also include a single-level Bike Car that is specially equipped to accommodate bicyclists.

All trains are operated in push-pull configuration with the cab-car end towards Washington.

All of the stations from Washington Union Station up to Halethorpe have high-level platforms, and all of the subsequent stations from West Baltimore up to Perryville, with the exception of Penn Station, have low-level platforms.
This precludes the use of MARC's ex-Metra low-level boarding gallery railroad cars on the Penn Line.
