There is no direct rail link between SFO and LAX; the practical trip uses Bay Area transit, Amtrak, and an LAX bus.

For travelers comparing a flight with a train from SFO to LAX, the first surprise is the airport wording. San Francisco International Airport has a BART station, but Los Angeles International Airport does not have an intercity train platform.
The workable rail trip is really three trips stitched together: reach an Amtrak station in the Bay Area, ride Amtrak to Los Angeles Union Station, then transfer to LAX by FlyAway bus or LA Metro. The scenic option is slow, the flight is faster, and the right choice depends on whether you want the rail experience or the shortest airport-to-airport trip.
Compare the rail-and-coach options before you commit, because the lowest fare is not always the least painful route:
Is There A Direct Train From SFO To LAX?
No direct train runs from SFO terminals to LAX terminals. Amtrak uses the station code LAX for Los Angeles Union Station, which is downtown Los Angeles, not the airport.
That station-code detail causes confusion. A booking result that ends at “Los Angeles, CA – Union Station (LAX)” still leaves you about 18 miles from the airport terminals by road, or a Metro-plus-shuttle transfer through the LAX/Metro Transit Center.
Airport-to-airport travelers who care mainly about time should usually fly. Rail makes sense when you want bigger seats, no airport security line for the long segment, and a California coast or Central Valley ride rather than a 90-minute flight.
The Practical Rail Route From SFO Airport
The simplest rail-heavy route is SFO AirTrain or walking to BART, BART to a transfer point, Caltrain or local transit to San Jose Diridon, Amtrak Coast Starlight to Los Angeles Union Station, then FlyAway or Metro to LAX. A rideshare from SFO to San Jose Diridon can cut transfer stress, but it raises the total cost.
The Coast Starlight is the cleanest single-train leg because it runs from the Bay Area to Los Angeles without the Bakersfield coach transfer used by the inland Amtrak route. The trade-off is timing: the southbound train is a daytime train from the Bay Area and reaches Los Angeles in the evening.
- Scenic rail choice: reach San Jose Diridon, then take the Coast Starlight south.
- More departure choice: use Amtrak’s Gold Runner route through the Central Valley with a bus link at Bakersfield.
- Simplest airport choice: fly SFO to LAX and save the train for a city-to-city trip later.
SFO To LAX By Rail: Every Route Compared
SFO to LAX by rail works best when you judge the whole chain, not just the Amtrak segment. The table below uses realistic planning ranges because local transfers, live fares, and traffic into LAX can move the total up or down.
| Route Choice | Realistic Time | Rough Cost Pattern |
|---|---|---|
| SFO to San Jose Diridon, Coast Starlight to Union Station, FlyAway to LAX | About 13 to 14 hours door to terminal | Variable Amtrak fare plus Bay Area transit and airport bus |
| SFO rideshare to San Jose Diridon, Coast Starlight to Union Station, FlyAway to LAX | About 12.5 to 13.5 hours | Higher total cost, fewer transfer risks |
| SFO to Emeryville, Coast Starlight to Union Station, FlyAway to LAX | About 14 to 15 hours | Similar Amtrak fare, longer train time |
| SFO to Bay Area Amtrak, Gold Runner to Bakersfield, coach to Los Angeles | About 10 to 12 hours to Union Station before LAX transfer | Often competitive when booked early |
| Direct SFO to LAX flight | About 1.5 hours in the air; 3.5 to 5 hours airport to airport | Often cheapest with no checked bag |
| Intercity bus from San Francisco area to Los Angeles, then airport transfer | About 8 to 10.5 hours before LAX traffic | Often the lowest cash fare |
| Drive or rental car between the airports | About 6.5 to 8.5 hours before stops and traffic | Gas, parking, rental, and one-way fees can add up |
When The Coast Starlight Makes Sense
The Coast Starlight makes sense when the ride is part of the trip, not just a way to reach a flight. Amtrak’s Coast Starlight timetable lists the southbound train at San Jose Diridon at 10:26 a.m. and Los Angeles Union Station at 9:11 p.m., a scheduled 10 hours 45 minutes before airport transfers.
San Jose is the better Bay Area boarding point if you are starting at SFO and want to keep the train ride shorter. Emeryville and Oakland work too, but they add more time on the train and may not reduce the transfer burden from the airport.
The Gold Runner route is less romantic, but it can be more useful. It runs through the San Joaquin Valley to Bakersfield, where Amtrak connection coaches continue to Southern California. Pick that route when the Coast Starlight time does not fit your day or when multiple departure choices matter more than scenery.
Timing tip: Do not plan a same-day flight out of LAX after a long Amtrak trip unless the gap is large. Long-distance trains can lose time, and LAX terminal traffic can eat the buffer.
How Do You Reach LAX After The Train?
Los Angeles Union Station gives you two practical public-transit choices to reach the airport: the nonstop FlyAway bus or LA Metro to the LAX/Metro Transit Center and the free airport shuttle. FlyAway is simpler from Union Station; Metro can work if your final stop is near the C Line or K Line.
FlyAway leaves from the Patsaouras Transit Plaza at Union Station East and runs straight to the terminals. LA Metro’s airport path uses the C Line or K Line to the LAX/Metro Transit Center, then a free shuttle to the terminal loop.
Choose FlyAway if you arrive tired, carrying bags, or running late. Choose Metro if you already understand the LA rail system, your fare setup is ready, and your timing gives you room for an extra transfer.
Where To Stay If You Break The Trip In Los Angeles
Los Angeles is easier after a long train day when your room matches your next move. Stay near Union Station for a late arrival and a morning Metro or FlyAway transfer, near LAX for an early flight, or in Downtown Los Angeles if you want dinner and a shorter ride from the train.
For a late Amtrak arrival, compare hotels around Union Station, Downtown Los Angeles, and LAX before picking the cheapest room:
Pick The Right Option For Your Trip
The right choice is simple once you separate the airport trip from the rail trip. Pick the Coast Starlight if you want one long scenic train leg and you can spend the whole day getting to Los Angeles.
- Fastest airport-to-airport: fly SFO to LAX.
- Most scenic rail trip: SFO to San Jose Diridon, Coast Starlight to Union Station, FlyAway to LAX.
- Most schedule-flexible rail option: Gold Runner through Bakersfield with the Amtrak coach connection to Los Angeles.
- Least transfer stress by rail: rideshare from SFO to San Jose Diridon, then Coast Starlight south.
- Safest same-day flight plan: arrive in Los Angeles the night before, sleep near LAX, and fly the next morning.
Check the current train, bus, and transfer mix side by side before paying, especially if your real destination is an LAX terminal rather than downtown Los Angeles:
