Train from Denver to Phoenix: Complete Planning Guide
Contents
Phoenix has no Amtrak station. There’s no direct train from Denver to Phoenix.
I’ve planned this trip multiple times, and the biggest myth is that Phoenix is on Amtrak’s rail network. It’s not—you’ll ride the Southwest Chief from Denver to Los Angeles, transfer to the Sunset Limited, and finish with an Amtrak Thruway bus from Maricopa. Because the two trains don’t connect on the same day, you almost always face a late-night arrival in Los Angeles and an early-morning departure, so factor in a hotel near Union Station.
Taking the train from Denver to Phoenix is a legitimate adventure, but it’s not a simple point-to-point ride. This guide breaks down the full route, the transfer logistics, and the common mistakes that turn a 26-hour trip into a 40-hour ordeal.
Key Takeaways
- There is no direct train; the journey requires a connection in Los Angeles and an Amtrak Thruway bus from Maricopa to Phoenix.
- Total travel time is at least 24 hours, often 26–30 hours, making it usually longer and more expensive than a direct flight.
- Book the entire itinerary on Amtrak.com as one ticket to get the protected Thruway bus connection.
Step 1: The Train from Denver to Phoenix Is Not a Single Train
The first thing any route planner does is map the actual rail network. Amtrak does not serve Phoenix with passenger trains. The closest Amtrak station to Phoenix is Maricopa, Arizona, roughly 35 miles south of the city. So any rail journey to Phoenix ends with a bus. That’s non-negotiable.
From Denver’s Union Station, you board the westbound Southwest Chief (Train 3). This train runs daily and reaches Los Angeles Union Station about 34 hours later if you stayed on, but you’ll get off in LA after roughly 24 to 26 hours. Then you transfer to the eastbound Sunset Limited (Train 2), which runs only three days per week. The Sunset Limited drops you at Maricopa Station around 2:55 AM, and from there an Amtrak Thruway bus completes the final 45-minute ride into Phoenix.
The Three-Leg Journey in Detail
Break the route into legs:
- Leg 1: Denver to Los Angeles on the Southwest Chief, about 1,200 miles, roughly 26 hours.
- Leg 2: Los Angeles to Maricopa on the Sunset Limited, about 650 miles, roughly 11 hours.
- Leg 3: Maricopa to Phoenix on Thruway bus, 35 miles, about 45 minutes.
Total travel time, including the forced layover in Los Angeles, typically lands between 28 and 36 hours door to door. A self-contained fact: The Sunset Limited runs only three days per week, which forces most travelers into an overnight stop in Los Angeles.

Step 2: Book the Entire Itinerary as One Ticket
The single most important move is booking the whole Denver-to-Phoenix itinerary on Amtrak.com as one reservation. Amtrak will sell you a ticket that includes the Southwest Chief, the Sunset Limited, and the Thruway bus connection. If you book the bus separately or use a third-party site that splits the segments, you lose the protected connection.
Why the Thruway Bus Connection Matters
When everything is on one ticket, Amtrak guarantees the bus will wait if your train runs late. If you miss the Sunset Limited because the Southwest Chief was delayed, Amtrak rebooks you on the next available departure—no extra charge. If you bought a separate bus ticket, that’s on you. The bus from Maricopa to Phoenix is not a scenic transfer; it’s a functional shuttle that departs quickly after the train arrives.
Fare Range and Sleeping Options
Coach seats on the Denver-to-Phoenix rail journey typically run $150 to $300 one way in advance. A roomette—a private cabin for two with seats that convert to beds—usually adds $400 to $700 over coach. A bedroom with an in-room toilet and shower can push the total over $1,000. Compare that to a Denver-to-Phoenix flight, which often runs $80 to $200 round trip. The train is almost always slower and more expensive than flying.
If you want sleeping accommodations, book early. The Southwest Chief has limited sleeper inventory, and the Sunset Limited runs even fewer cars. A roomette on both trains might be possible on one ticket, but you may have to accept a coach seat on the shorter Maricopa leg.
Step 3: Plan the Los Angeles Layover Like a Mission Brief
Los Angeles Union Station is the pivot point. The Southwest Chief typically arrives from Denver around 8:00 AM. The eastbound Sunset Limited to Maricopa departs at 10:00 PM on its three operating days (usually Sunday, Wednesday, and Friday—check the current schedule). That’s a 14-hour gap. You are not sleeping on a train; you are waiting in a city.
Hotel Selection and Luggage Storage
Book a hotel within walking distance of Union Station. The adjacent Chinatown and downtown hotels are fine, but avoid anything requiring a taxi after midnight unless you’re familiar with LA. You can check into a room by mid-morning, rest, and walk back to the station around 9:30 PM. Union Station has a paid luggage storage service, but it’s easier to leave bags at your hotel.
A self-contained statement: Los Angeles Union Station is a five-minute walk from several downtown hotels, but the area around the station after dark requires standard urban awareness.
For travelers heading east instead, the Utica to NYC train route offers a much simpler corridor experience with no overnight transfer.
Step 4: The Maricopa Thruway Bus and Phoenix Arrival
The Sunset Limited reaches Maricopa Station in the middle of the night—typically 2:55 AM. The Thruway bus boards immediately after passengers detrain. The ride north to Phoenix takes about 45 minutes, dropping at Phoenix Sky Harbor Airport and sometimes a downtown location. Do not expect a scenic desert vista; it’s dark, and you’ll probably sleep.
What to Expect at Maricopa
Maricopa Station is a small, uncovered platform with minimal shelter. There is no ticketing desk, no cafe, and no staff beyond the train crew. The bus driver will help load luggage, but carry essentials in a personal bag. The temperature in Maricopa during summer nights can still be above 90°F, so have water.
Self-contained statement: The Thruway bus from Maricopa to Phoenix is included in a properly booked Amtrak ticket, and it waits for the train even if the train is late.
Step 5: Contingency Planning — What Goes Wrong and How to Recover
A military-precision route plan includes bail-out points. For this rail journey, the biggest failure points are missed connections and track delays. The Southwest Chief shares track with freight railroads and can arrive Los Angeles 4 to 6 hours late. If you miss the Sunset Limited because of a late arrival on a departure day, Amtrak will rebook you—but the next Sunset Limited may be two days later.
Alternative Escape Routes
If you’re stuck in LA with a blown connection, your fastest fallback is a Greyhound bus to Phoenix, which takes about 7 hours from LA’s downtown station. You can also fly from LAX or Burbank to Phoenix in 90 minutes. Neither is covered by your Amtrak ticket, but they beat waiting two extra days.
If you’re headed to Texas instead, the best train to Houston options show how the Sunset Limited can be used eastbound with a similar three-day schedule.
Scenic Stretches Worth the Trip
The Denver-to-LA portion on the Southwest Chief is the highlight. You’ll pass through the Colorado Rockies, including Moffat Tunnel at 9,239 feet, then across Raton Pass and the high desert of New Mexico. Much of this scenery is only visible from a train because there are no parallel highways. The Maricopa leg, in contrast, is flat desert in the dark—nothing to see.
Frequently Asked Questions

The Southwest Chief from Denver to Los Angeles takes about 26 hours, the layover in LA is typically 14 hours, the Sunset Limited to Maricopa takes about 11 hours, and the Thruway bus adds 45 minutes. The Sunset Limited’s limited schedule often forces an overnight hotel stay in Los Angeles.
How much does a train ticket from Denver to Phoenix cost?
