Amtrak/MARC Station Parking

10-minute shuttle from the BWI Rail Station to the Terminal

The Amtrak/MARC Station Parking at BWI sits by the BWI Rail Station, not at the Terminal, and ties directly into MARC and Amtrak service toward Baltimore and Washington, DC. It functions first as a commuter rail lot, with signage focused on train riders rather than air travelers. Think of it as “train-first” parking that can double as an airport option if your trip already involves the rail station.

Shuttles from the rail station to the Terminal run roughly every 10–15 minutes, with the ride taking about 10 minutes depending on traffic on the loop road. The bus is free and drops you at the main Terminal, so you clear security there like any other BWI passenger. Build at least 30 extra minutes into your schedule to cover parking, waiting on the shuttle, and the drive over.

Reviews consistently say this lot comes in cheaper per day than the official airport garages, but it fills quickly on weekdays thanks to MARC commuters arriving before 8:00 a.m. One Google reviewer flat-out warns not to roll in at 9:00 a.m. expecting open spaces. Pricing skews toward day-use rail riders, so long-term airport parking feels more like a workaround than the primary intent.

Regulars on MARC talk about getting there very early to grab a space and often avoiding overnight parking altogether. Others say they only leave a car here for a flight when their trip already starts or ends on MARC or Amtrak, to stay aligned with the posted rail-use focus. If you’re driving in solely for a flight, you may be better off with official BWI parking instead of gambling on commuter demand.

Watch out for reports of the lot feeling sketchy late at night and the usual warnings about break-ins. Multiple reviews mention not leaving valuables visible in the car and parking under lights when possible. Practical tip: if you need this lot on a weekday and plan to fly, aim to park before 7:30 a.m., grab a photo of your row, and head straight to the next Terminal shuttle instead of lingering at the station.
