What's the Fastest Way to Get From Baltimore to Washington DC?

The MARC Brunswick Line train is fastest for most travelers, covering 40 miles in about 60 minutes with departures roughly every 30 to 60 minutes on weekdays. The Northeast Regional Amtrak train takes 90 minutes but runs seven days a week. Driving via I-95 South typically takes 60 to 90 minutes depending on traffic, while Greyhound and Megabus offer budget alternatives at 90 to 120 minutes. Choose the train for reliability and zero traffic risk; choose driving only if you need a car in Washington DC.

Train: MARC and Amtrak

The Maryland Area Regional Commuter (MARC) rail system operates the most frequent connection. The Brunswick Line departs from Baltimore's Penn Station at 1500 North Charles Street and arrives at Union Station in Washington DC. On weekdays, trains run from approximately 5:30 a.m. to 11:30 p.m., with peak-hour service every 30 minutes during rush periods (6:00 to 9:30 a.m. and 3:30 to 7:00 p.m.) and every 60 minutes midday. Weekend service is less frequent; verify the current schedule at the MARC website before traveling Saturday or Sunday.

One-way fares are generally cheaper on MARC than Amtrak but vary by time of travel. A weekday off-peak ticket typically costs less than a rush-hour ticket. Purchase tickets at the station or through the MTA's online portal; many commuters use the MTA's transit card system for frequent trips. Allow 15 minutes to reach the platform, and arrive at least 10 minutes before departure.

Amtrak's Northeast Regional train also departs from Penn Station and reaches Union Station. This train takes longer (90 minutes) but operates daily including holidays, which matters if you travel on Christmas or Thanksgiving. Amtrak fares are higher than MARC; check Amtrak's website directly for current prices, as they vary significantly by booking date and time.

Driving via I-95 South

From downtown Baltimore, take I-95 South for approximately 38 miles. During normal traffic conditions (roughly 10 a.m. to 3 p.m. on weekdays), the drive takes 60 to 75 minutes. Rush hour traffic, especially afternoon congestion heading south, can extend this to 90 to 120 minutes. Evening rush hour (4:00 to 7:00 p.m. weekdays) is the worst time to drive this route.

You'll pass through Maryland for the entire route and need to pay tolls on the Fort McHenry Tunnel (between I-95 northbound and southbound near the harbor). The tunnel toll for a standard passenger vehicle is a specific fee; check the Maryland Transportation Authority website for current rates, as these change. You can prepay using E-ZPass or pay with a license plate toll (a bill mailed to the vehicle's registered owner).

Parking in Washington DC is expensive and often difficult. Street parking rates vary by ward and time of day, starting around $2.00 to $3.00 per hour in many neighborhoods. Parking garages near Union Station or major attractions run $10 to $25 per day. Factor parking costs into your trip budget if you're driving.

Bus Services

Greyhound and Megabus both serve this route. Greyhound typically departs from the Greyhound station at 210 West Fayette Street in Baltimore and arrives at the Union Station terminal in Washington DC. Travel time is 90 to 120 minutes depending on the number of stops. Tickets are often $10 to $30 one-way if booked in advance; prices rise closer to travel dates.

Megabus operates from similar departure points and undercuts Greyhound on price, sometimes offering tickets for under $5 if booked weeks ahead, though availability is limited. Both services are cheaper than train or car rental but slower and less comfortable for most travelers.

Practical Considerations

If you're staying overnight, you may not need to return the same day. Many Baltimore hotels offer discounted parking for multiday guests, and Washington DC hotels are generally more expensive than Baltimore's, so some travelers prefer a day trip.

If you're traveling during rush hour, the train's 60-minute guarantee beats driving's unpredictability. If you're arriving with three or more people and need ground transportation in DC, the cost-per-person economics of driving may improve.

Union Station in Washington DC is centrally located and has connections to the Metro, Amtrak, and regional bus services, making onward travel straightforward. Penn Station in Baltimore is less convenient for car rental; Enterprise, Hertz, and Budget have branches nearby but require a taxi or rideshare to reach them from the station.

Can I take a regional bus cheaper than the train? Yes; Megabus and Greyhound charge $5 to $30 one-way compared to MARC's typical $12 to $20, but journey times are 30 to 60 minutes longer.

Is there night service between Baltimore and DC? MARC's last northbound train from Union Station to Penn Station departs around 11:30 p.m., and Amtrak runs limited late-evening service; check current schedules as these change seasonally.
