Quick Answer
The fastest and most cost-effective way to get from Ronald Reagan Washington National Airport (DCA) to Washington Union Station is by taking the Washington Metro (subway). The journey on the Yellow Line towards Fort Totten/Greenbelt takes approximately 15-20 minutes and costs only $2.00 – $2.25 (off-peak) or $2.25 – $3.85 (peak). No transfers are needed if you board the Yellow Line. For direct, door-to-door service, a taxi or ride-share (Uber/Lyft) takes 10-15 minutes but costs $15 – $25+, depending on traffic.
1. Washington Metro (Subway) – The Best Overall Choice
The Washington Metropolitan Area Transit Authority (WMATA) Metro is highly recommended for its speed, frequency, and low cost. The DCA Metro station is connected to Terminals 1 and 2 via an indoor walkway, making it accessible regardless of weather.
Step-by-Step Guide:
- Find the Station: Follow signs for “Metro” from the baggage claim area. The walk takes 5-10 minutes.
- Purchase a SmarTrip Card: Buy a physical card ($2) or use a digital SmarTrip card via the official WMATA app. Load it with sufficient fare (minimum $2).
- Board the Train: Take the Yellow Line in the direction of Fort Totten/Greenbelt. Ensure the train is marked for Greenbelt, not Huntington, to avoid a transfer.
- Alight at Gallery Pl-Chinatown: Ride for about 10 minutes to this station.
- Transfer to the Red Line: Cross the platform to board the Red Line towards Glenmont.
- Arrive at Union Station: Ride for one stop (approx. 2 minutes) and exit at “Union Station”. Follow signs to the main train hall.
Key Details & Tips:
- Travel Time: 15-20 minutes total (including transfer).
- Fare: Peak (Weekdays 5-9:30 AM & 3-7 PM): ~$3.85. Off-Peak: ~$2.25. Pay with SmarTrip for the lowest fare.
- Frequency: Trains run every 6-12 minutes.
- Accessibility: All stations and trains are wheelchair accessible. Elevators are available.
- Luggage: Avoid rush hours (7-9 AM, 4-6 PM) if you have large suitcases.
- Direct Yellow Line? Some Yellow Line trains terminate at Mt Vernon Sq. Check the destination sign; a Greenbelt-bound train is required for a direct ride to Gallery Pl.
3. Bus & Shuttle Services – Budget-Friendly Alternatives
While slower, buses can be a scenic and ultra-cheap option. No direct bus runs between DCA and Union Station; a transfer is required.
Metrobus Option (WMATA Bus):
- Route: Take Metrobus B30 from DCA to the Greenbelt Metro Station (approx. 30-40 mins). Then, take the Green Line Metro to Gallery Pl and transfer to the Red Line to Union Station. This is not recommended for this short trip due to complexity.
- Better Local Bus: Use the DC Circulator or other Metrobus routes only if you are already familiar with the system.
Private Airport Shuttles:
Shared-ride shuttles like SuperShuttle (operating in some areas) or hotel shuttles are an option.
- Cost: ~$20-$35 per person for shared service.
- Drawback: Travel time can be lengthy (45-60 mins) as the van makes multiple stops.
- Booking: Pre-booking online is often required.
Verdict: For the specific journey from DCA to Union Station, the Metro is superior in every aspect to the bus. Shuttles are only worth considering if you have a lot of luggage and a hotel drop-off near Union Station is included.
4. Train (Amtrak / VRE) – An Indirect Rail Option
While Union Station is a major train hub, taking a train from DCA is impractical. Here’s why and the rare scenario where it might make sense.
Virginia Railway Express (VRE):
- The nearest VRE station is Crystal City, a 10-minute Metro ride or taxi from DCA.
- VRE only operates on weekdays during peak commuter hours. It runs to Union Station, but the schedule is infrequent.
- Cost: ~$4.75 - $7.25.
- Conclusion: Not a viable option for most travelers due to limited schedule and the need to get to Crystal City first.
Amtrak:
There is no Amtrak service from DCA. You must take the Metro or a taxi to Union Station first to board an Amtrak train to other cities.
When This Section is Useful: If you are arriving at DCA and your final destination is a Virginia suburb served by VRE during weekday rush hour, you could theoretically take Metro to Crystal City, then VRE out. However, for going to downtown DC/Union Station, it's circuitous.
5. Driving & Parking at Union Station
If you are picking up a rental car at DCA or being picked up, here’s what you need to know about driving to Union Station.
Driving Route:
- Most Direct: Take the George Washington Memorial Parkway north, then follow signs for I-395 North/US-1 North towards the city. Take the exit for Massachusetts Ave NE/US-50, which leads directly to the front of Union Station.
- Distance & Time: About 4.5 miles. Takes 10-15 minutes without traffic, but rush hour can easily double or triple this time.
- Tolls: The I-395 tunnel has a toll (approx. $2-$4) for cars without an E-ZPass during peak hours.
Parking at Union Station:
Union Station has a large short-term and long-term parking garage.
| Parking Type | Rate (Approx.) | Notes |
|---|---|---|
| Short-Term (Hourly) | $6 - $12 per hour | Max daily rate ~$35-$45 |
| Long-Term (Daily) | $25 - $35 per day | Better for overnight or multi-day parking. |
| Valet Parking | $40+ per day | Available for convenience. |
Pro Tip: Use parking apps like SpotHero to reserve and prepay for parking in lots/garages near Union Station, often at a significant discount.

7. Traveler Tips & Insider Advice
Essential Tips for a Smooth Journey:
- Download Essential Apps: WMATA Metro (for real-time schedules), Uber, Lyft, and SpotHero (for parking). Google Maps/Apple Maps are excellent for transit directions.
- Get a SmarTrip Card/App: This is the key to seamless Metro and bus travel. The physical card costs $2 but is reusable. The digital card in the app is even more convenient.
- Handle Luggage Smartly:
- If you have very large bags and don't want to take them on Metro, consider a luggage storage service like Bounce near DCA or Union Station for a few hours (~$6/bag/day).
- On Metro, use the end cars, which are often less crowded.
- Navigate Union Station Like a Pro: The Metro exit deposits you in the lower level. Follow signs for “Train Concourse” to reach Amtrak/VRE/MARC gates, or “Main Hall” for the beautiful waiting area, shops, and food court.
- Time Your Arrival:
- Weekday Rush Hours (7-10 AM, 4-7 PM): Metro cars and roads are packed. Allow extra time.
- Late-Night Arrivals (after 11 PM): Metro runs until midnight Sun-Thu, 1 AM Fri & Sat. For flights arriving after Metro closes, your only options are taxi, ride-share, or a 24-hour hotel shuttle if pre-arranged.
- Accessibility: All DCA terminals, the Metro, and Union Station are fully wheelchair accessible. Use elevators in Metro stations. For specialized paratransit, book MetroAccess in advance.
FAQs: Getting from Reagan National (DCA) to Union Station
Is there a direct train from Reagan Airport to Union Station?
No, there is no single “direct train.” However, the Washington Metro provides a nearly direct route: take the Yellow Line (Greenbelt bound) to Gallery Pl-Chinatown, then the Red Line (Glenmont bound) for one stop to Union Station. This involves one simple, cross-platform transfer and is the closest to a direct rail connection.
What is the cheapest way to get from DCA to Union Station?
The absolute cheapest way is the Washington Metro during off-peak hours, costing just $2.00 – $2.25. Even during peak hours ($3.85), it is vastly cheaper than any road-based option.
How do I get from DCA to Union Station late at night?
If you arrive after the Metro has closed (midnight or 1 AM), your primary options are taxis (available 24/7 at stands) or ride-share services (Uber/Lyft). Expect slightly higher prices due to late-night surcharges. Some airport shuttle services may also offer pre-booked late-night rides.
Is it easy to walk from the DCA Metro station to my terminal?
Yes, it's very easy and covered. The DCA Metro station is connected to both Terminal 1 (by a walkway) and Terminal 2 (via a pedestrian bridge and moving walkways). Follow the clear “Metro” signs. The walk takes 5-10 minutes from baggage claim.
Is the Metro from DCA to Union Station safe?
Yes, the Metro is generally safe for travelers, especially on this short, well-traveled route during daytime and evening hours. As in any major city, practice standard awareness: keep valuables secure, be mindful of your surroundings in stations, and travel with others if very late at night.
I have a lot of luggage. Should I still take the Metro?
It depends. If you have 1-2 manageable suitcases and avoid weekday rush hours, the Metro is fine. If you have multiple large, heavy bags, or are traveling with young children and strollers, the convenience of a taxi or ride-share may be worth the extra cost to avoid crowded trains and station escalators.
Can I use my credit card on the Metro, or do I need cash?
You cannot tap a regular credit card at Metro gates. You must use a SmarTrip card (physical or digital in the app). You can purchase and load a physical card with cash or credit/debit at airport station vending machines. Setting up the digital card in the WMATA app before arrival is highly recommended.
How early should I leave DCA to catch a train at Union Station?
If your Amtrak/MARC/VRE train departs from Union Station, plan to arrive at Union Station at least 30-60 minutes before your train’s departure. Therefore:
- By Metro: Leave DCA 50-70 minutes before your train time (20 min travel + 30-50 min buffer).
- By Taxi/Ride-Share: Leave DCA 45-60 minutes before (15 min travel + 30-45 min buffer, accounting for potential traffic).
