Washington DC and Baltimore sit close enough together that the train is, without much competition, the obvious way to travel between them. It is one of the shortest, simplest journeys covered anywhere on this site, and the choice mostly comes down to which train service suits your budget and travel day. Here is how the rail options and the drive compare.
The best way: MARC Penn Line or Amtrak
The MARC Penn Line commuter train runs frequently between Washington Union Station and Baltimore's Penn Station, taking around 30–40 minutes, and is by far the cheapest rail option — it is a commuter service, priced accordingly, though it runs primarily on weekdays with a reduced or absent weekend schedule depending on the season, so check current timetables if travelling on a Saturday or Sunday. Trains run frequently during weekday peak periods, with a thinner but still workable off-peak and midday schedule, making it entirely feasible to treat Baltimore as a same-day trip from Washington without staying overnight.
Amtrak's Northeast Corridor trains — both Acela and Northeast Regional — also run this stretch, taking a similar 30–40 minutes, with the advantage of running every day of the week, including weekends, and continuing on to New York, Philadelphia and Boston, which makes them useful if Baltimore is a stop on a longer Northeast Corridor trip such as New York to Washington or Washington to Philadelphia. Fares are considerably higher than MARC for the same short hop, so weekday travellers who only need Washington to Baltimore usually save by taking MARC instead. For the fuller picture of how this corridor works, see the USA by train.
Both services arrive at Baltimore Penn Station, a short taxi or light rail connection from downtown and the Inner Harbor. Reservation rules differ from many long-distance US trains — see seat reservations explained for the general picture of when a reservation is genuinely required.
Driving: comparable time, more hassle
The drive is about 65 km up Interstate 95, taking 45 minutes to over an hour depending on traffic, which is notoriously heavy on this stretch during rush hour on weekdays. Given that the train covers the same distance in similar or less time, without traffic risk or the cost of parking in either city, driving offers little advantage on this particular route unless you specifically need a car once in Baltimore. General guidance on driving rules and hiring a car in the country is covered in driving in the USA.
Parking in both downtown Washington and around Baltimore's Inner Harbor is limited and can be expensive, which further narrows the practical advantage of a car for a simple point-to-point trip. Drivers should also budget extra time around the Baltimore Harbor Tunnel and Fort McHenry Tunnel, both toll crossings on I-95 that can back up badly during the evening rush.
Flying: not applicable
There is no meaningful flight market between Washington and Baltimore — the two cities are close enough that this is simply not how anyone travels between them, and Baltimore-Washington International Airport itself sits roughly midway between the two downtowns and is well connected to both by the same MARC and Amtrak lines. Travellers arriving from overseas via Washington should check the US ESTA before their trip, and those flying into Boston or Chicago as part of a wider Northeast itinerary can see Boston airport to the city or Chicago airport to the city for comparable transfer guides.
What to expect on arrival
Baltimore Penn Station sits a short distance north of downtown, with a taxi rank, rideshare pickup and connections to the city's light rail and bus network right outside. It is a handsome, historic building in its own right, and a straightforward, well-signposted place to arrive even on a first visit. Washington's Union Station, similarly, connects directly into the Metro system, so neither end of this journey requires much guesswork once you step off the train.
Making the most of a short trip
Because the journey itself is so quick, many visitors treat Washington and Baltimore as an easy joint day trip or overnight add-on rather than two entirely separate stops. Baltimore's Inner Harbor, museums and the historic Fell's Point neighbourhood are all within easy reach of Penn Station by taxi, rideshare or the local light rail, so there is no need to hire a car purely to get around once you arrive. The same applies in Washington, where Union Station sits close to the Capitol and the National Mall.
If your trip continues further afield afterwards, this short hop connects neatly into the wider Northeast Corridor network — from Baltimore, the same Amtrak and MARC lines run on to Philadelphia and New York, making it easy to fold into a longer coastal itinerary without ever needing to drive.
Which should you choose?
For weekday travel, MARC is the cheapest and most practical choice. For weekends, holidays, or if you are continuing further up the Northeast Corridor, Amtrak is the reliable option, at a higher fare. Driving offers little benefit over the train on this short, traffic-prone stretch of I-95 unless a car is genuinely needed at your destination. Either way, this is one of the simplest, lowest-risk short hops covered anywhere on this site — a genuinely easy add-on to a Washington trip.
