Amtrak Routes With Multiple Numbers: What You Need To Know

Amtrak routes with multiple numbers confuse many first-time travelers. You search for the Lake Shore Limited and see trains 48 and 448, both leaving Chicago at 9:30 PM, sometimes with different prices. What gives? These aren’t separate trains. Three Amtrak routes physically split or merge along the way, resulting in different route numbers for each segment. This guide will show you which routes do this, what to expect when trains split or merge, and how to choose the right ticket for your trip.

Why does Amtrak do this?

As I mentioned in the introduction, Amtrak does not run back-to-back trains; instead, it operates three long-distance routes on which trains split or converge.

Splitting trains enables Amtrak to serve more areas more efficiently with fewer resources.

With these trains, each section has a route number; the base section has the base number, and the offshoots have a number added to the base number.

For example, the New York section of the Lake Shore Limited is 49, while the Boston South Station section is 449.

The Lake Shore runs as a single train between Albany and Chicago, but after Albany, the Lake Shore Limited splits into two trains, serving New York and Boston, as well as their intermediate stations.

What should you expect when a train is separated or joined together?

When the train is being separated or coupled, you may stay on board or step off to observe. Please listen carefully to the staff’s instructions. If you choose to step off, please stay close to your car and return on time; the train will depart without you if you are not on board.

If you stay on board, please be prepared for some jolts during the coupling process. The locomotive will disconnect from the train cars, temporarily cutting power to the entire train. This means that the lights will briefly turn off and switch to emergency lighting, the HVAC system may stop working, and the bathroom and food service will be unavailable. Please plan accordingly.

The Amtrak Routes with Multiple Numbers

I use “build point” to identify where trains converge or diverge.

Empire Builder 7, 8, 27, & 28

Trains 7 and 8 are the main trains for this route.

  • Destinations and route number
    • 7 Chicago to Seattle
    • 8 Seattle to Chicago
    • 27 Chicago to Portland
    • 28 Portland to Chicago
  • Build point
    • Spokane, WA

The cafe car is on the Portland section for the Builder, and the dining car is on the Seattle side. If you need food and are traveling west, you should go early.

Lake Shore Limited 48, 49, 448, & 449

  • Destination and route number
    • 48 Chicago to New York
    • 49 New York to Chicago
    • 448 Chicago to Boston
    • 449 Boston to Chicago
  • Build point
    • Albany-Rensselaer, NY, (ALB )

The cafe car is on the Boston section, and the Sleeper Lounge (the flex dining car is on the NYP.

Texas Eagle 21, 22. 321, 322. 421 & 422/ Sunset Limited 1 & 2

The Sunset itself does not split or merge, but cars from the Texas Eagle are added to or removed from this train.

If you are traveling east from San Antonio, TX, to Los Angeles, you may see options for trains #1 and #421. For a westbound journey, you can choose either route 2 or route 422.

Depending on the number, you could be on either train, but that is one train.

Destination and route numbers

South/Westbound

  • 21 Chicago to San Antonio, TX
  • 321 Chicago to St Louis, MO
  • 421 Chicago to Los Angeles, CA

North/Eastbound

  • 22 San Antonio, TX to Chicago
  • 322 St Louis, MO to Chicago
  • 422 Los Angeles, CA to Chicago

Build points

St Louis for the “300” cars

San Antonio for the “400” cars

The Texas Eagle, which runs between Chicago and San Antonio, often features a combined cafe-dinner car and flex dining options. From San Antonio to LA, it has a full dining car with traditional dining and a cafe car.

These trains are put together at night or early in the morning. During that time, you may not have power or heating/AC. It doesn’t take them too long to make this move, and they are gentle when moving cars, or at least they try to be.

Boarding and Riding Amtrak Routes with Multiple Numbers

NYP Loading
Passengers getting ready to board the Lake Shore Limited at New York Penn Station.

When boarding the train, be sure to have your ticket ready and follow the instructions carefully. The coach cars for each section are typically grouped in the middle of the train, while the sleeper cars are located elsewhere. For example, the Seattle sleeper cars on the Empire Builder are at the front of the train, while the Portland sleeper cars are at the back.

If your destination is before the split point, conductors can seat passengers from both sections together in the same car. For example, passengers in coaches 7 and 27 might share a car if they’re disembarking before Spokane.

Once you’re on board, you’re welcome to walk around and step off for fresh air breaks. Please return to your assigned car and seat, as conductors need to locate you before your stop.

Please do not change seats or move to another car without first asking the staff.

If you are in the wrong car when the train splits, you might end up at the wrong destination. Additionally, if you switch to a different car, you may find that the doors do not open at your station. Not all doors open at every station, so Amtrak tries to seat you in a car that will have open doors at your stop. If you are in a car with doors that do not open, you will need to walk to another car with open doors to exit. By the time you reach the “right car,” the train could already be on its way. Amtrak will let you know if not all doors open.

Making Reservations for Amtrak Routes with Multiple Numbers

The biggest takeaway

The best takeaway from this article is to make a reservation that fits your budget and meets your accommodation needs.

If you take the Empire Builder from Milwaukee to La Crosse, WI, it doesn’t matter whether you’re on train 7 or 27; both “trains” will arrive at the same time, so either works and is “right.” In this case, the main difference is that if you pick 27, you will walk to the second-to-last car on the train, which is closer to the lounge car.

Price difference

The price differences between sections are due to Amtrak’s “bucket system,” a common practice across many transportation industries. Amtrak reserves a set number of seats for each price bracket. After all the seats in the first bucket sell out, the price jumps to the next bucket. This pricing remains in effect until the section or train sells out.

Multiple train numbers
Examples of Amtrak trains with multiple train numbers

The ticket system treats train sections separately, which can lead to price differences.

There are times when a lower price is not convenient. For example, a multiple-train option might be available if you travel from Milwaukee to Portland, OR.

For example, it may offer a roomette on train 7 (Seattle Builder) and then switch you to a roomette in the 27-sleeper car for the Spokane, WA, stop. This change does not happen at a convenient time for most people. If your next room is available, you may be able to change early, but this is not guaranteed.

Paying a few extra dollars may be worth it to avoid that hassle. This situation can also occur with coach tickets.

The moral of the story

The main takeaway is to choose the more affordable option unless switching cars at inconvenient times is required.

When boarding, listen for instructions to ensure you board the correct car. When traveling, always know your train’s name and number, as well as its destination (or layover). Knowing the last stop of your route is helpful as well.

I hope this clarifies the confusion and does not create new ones.

    The Amtrak LSL timetable lists an addition 4-digit number (1448/1449), which shaves a little time off the destinations. Any idea what that’s for?

    1. Kevin Monteith

      From my understanding, the 1448 and 1449 are projected schedules that could go live in 2027. I am not sure why they would display them so early.

      I hope that helps!

      Safe travels and happy planning,
