Yes hun, they will help you. There is a help center there and depending on how long the layover is , you can take a stroll around DC and they have a lot of stuff you can do, a big food court amd plenty of little stores and coffee shops and bathrooms as well. Before you get off the train ask one of the ppl there and they can direct you where ever you need to go. Safe travels!

no

No, there's a very limited schedule you should check before you go.

I'm not sure if there is a parking lot. However, to pick up someone you can drive to the front or sides of the building depending on where they are standing to get picked. There are side entrances to the station too so be sure to get clarity prior to picking up anyone.

Huge food court on lower level. Several other places on main level, including Shake Shack

Hex no!! Their not trying to have folks come back like that... just keep it moving when you pass through💯👀🤣

Amtrak goes directly to BWI and the MARCs trains go to BWI as well. Take a regional Amtrak train from Union Station to BWI and trip is about 25 minutes. The first stop is New Carrollton and the stop after is BWI-Thurgood Marshall Airport
