Understanding Trains, Subways & Transfers

Trains and subways can help you travel quickly between neighborhoods, cities, and even states. They can be especially useful when traffic is heavy, parking is limited, or your destination is far from home.

The first few trips may feel complicated. Stations can have multiple entrances, platforms, tracks, and lines, and you may need to transfer from one train to another. Once you understand the basic signs and steps, however, train travel becomes much more manageable.

You do not need to memorize the entire system. You only need to understand the stations, trains, and transfers required for your trip.

Types of Train Service

Different train systems serve different purposes.

Subways and Metro Systems

Subways and metro trains usually operate within a city or metropolitan area. They may run underground, above ground, or at street level.

They generally:

  • Make frequent stops
  • Run throughout the day
  • Use route names, letters, numbers, or colors
  • Allow transfers between lines
  • Charge a flat fare or distance-based fare

Light Rail

Light-rail trains usually serve cities and surrounding communities. They may travel on dedicated tracks, along streets, or through underground sections.

Light rail may require passengers to purchase or validate tickets before boarding rather than passing through a turnstile.

Commuter Rail

Commuter trains connect cities with surrounding suburbs and communities. They usually travel farther and make fewer stops than subways.

Commuter rail may:

  • Use zone-based or distance-based fares
  • Have separate peak and off-peak prices
  • Run less frequently outside commuting hours
  • Require a ticket for a specific destination
  • Charge more if you purchase a ticket onboard

Intercity Trains

Intercity trains travel between different cities or regions. They usually require advance tickets and may have assigned seats, luggage rules, and specific boarding procedures.

Start With the Exact Destination

Before choosing a train, write down:

  • The complete destination address
  • The nearest station
  • The entrance you need to use
  • The date of travel
  • The time you need to arrive
  • The station closest to your starting point
  • Any accessibility needs
  • A telephone number for your destination

The station with the same name as your destination is not always the closest or easiest option. Another station may require less walking, have an accessible entrance, or provide a simpler route.

A large location such as a hospital, college, airport, or office complex may be served by several stations. Check which one is closest to the entrance you need.

Understanding Lines and Routes

Train and subway lines may be identified by:

  • A letter
  • A number
  • A color
  • A name
  • A destination
  • A combination of these

For example, a system might have:

  • The A Train
  • Line 4
  • The Red Line
  • The North Shore Branch
  • The Airport Express

Colors are helpful, but do not rely on color alone. Printed maps, signs, or digital screens may make similar colors difficult to tell apart. Always check the line’s complete name, letter, or number.

Multiple train services may share the same platform or tracks for part of their routes. Make sure the arriving train is the specific one you need.

Understanding the Direction of Travel

Most lines operate in two directions. The direction may be identified by:

  • The final station
  • A major station
  • The neighborhood served
  • Northbound or southbound
  • Eastbound or westbound
  • Inbound or outbound
  • Uptown or downtown

The same line name will appear in both directions, so checking only the line is not enough.

For example, both trains may be called the Green Line, but one may travel toward Central Station while the other travels toward Riverside.

Before entering a platform, confirm:

  1. The line name, number, or letter
  2. The direction of travel
  3. The train’s final destination
  4. Whether it stops at your station

If you are uncertain, ask a transit employee:

“Which platform do I need for the train to __________?”

Local, Express, and Limited-Stop Trains

Some train lines offer more than one type of service.

Local Trains

Local trains stop at every station along the route.

Express Trains

Express trains skip selected stations to travel more quickly between major destinations.

Limited-Stop or Peak-Service Trains

These trains stop only at certain stations or operate only during specific hours.

An express train may pass directly through your destination without stopping. A local and express train may also share the same platform.

Before boarding, check:

  • The train’s destination sign
  • The platform display
  • The route map
  • The list of upcoming stops
  • Service announcements

If you accidentally board an express train, you may need to travel to the next express stop and transfer to a local train traveling back in the opposite direction.

Reading a Train or Subway Map

A transit map shows how the system’s lines and stations connect.

It may include:

  • Train lines
  • Station names
  • Transfer stations
  • Bus connections
  • Airport connections
  • Accessible stations
  • Local and express stops
  • Fare zones
  • Service branches
  • Terminals

To plan your trip:

  1. Find your starting station.
  2. Find your destination station.
  3. Identify the line connecting them.
  4. Check the direction of travel.
  5. Look for any transfers.
  6. Count or review the stops.
  7. Confirm whether each train stops where you need it.
  8. Check accessibility information if needed.

A map may not represent actual geographic distance. Two stations that appear close together on the map may be several blocks apart, while stations that look far apart may be connected within the same building.

What Is a Transfer?

A transfer means changing from one train, subway line, bus, or other transportation service to another during the same trip.

You might transfer:

  • Between two subway lines
  • From a local train to an express train
  • From a subway to a bus
  • From a commuter train to a subway
  • Between trains operated by different agencies
  • Between platforms inside the same station

Some transfers occur within one station. Others require you to leave the station, walk to another entrance, or pay another fare.

Planning a Transfer

Before beginning your trip, identify:

  • The station where you will transfer
  • The line or train you need next
  • Its direction or final destination
  • Which platform you need
  • Whether you must use stairs, elevators, or escalators
  • How much walking is required
  • Whether you must leave the paid area
  • Whether another fare is required
  • How much time you have between trains

A transfer station may be large and busy. Give yourself extra time, especially if you are unfamiliar with it.

If your trip uses commuter or intercity trains with scheduled departure times, allow enough time for delays. Missing a connection may mean waiting much longer than missing a frequent subway train.

Following Transfer Signs

When leaving the first train, look for signs showing:

  • The next line’s name, number, letter, or color
  • The direction you need
  • The final destination
  • Platform or track numbers
  • Arrows
  • Elevators
  • Accessible routes
  • Exits

Do not automatically follow the largest crowd. Other passengers may be traveling to a different line or exit.

Pause in a safe location if you need to review the signs. Avoid stopping at the bottom of stairs, directly in front of train doors, or in the middle of a busy walkway.

Platforms, Tracks, and Stations

A station may contain:

  • One or more entrances
  • Ticket machines
  • Fare gates or turnstiles
  • Customer-service booths
  • Mezzanines or upper levels
  • Several platforms
  • Multiple tracks
  • Stairs, escalators, and elevators
  • Waiting areas
  • Restrooms
  • Shops or food vendors
  • Several street exits

A platform is the area where passengers wait. The track is where the train travels.

Track assignments may change, particularly on commuter and intercity rail systems. Check the electronic departure board and listen for announcements before boarding.

Finding the Correct Entrance

Different station entrances may lead to:

  • Different platforms
  • Opposite directions
  • Accessible elevators
  • Separate train lines
  • Different street exits

Some smaller subway entrances provide access to only one direction. If you enter through the wrong one, you may need to leave, cross the street, and enter again. Depending on the fare system, you might also need to pay again.

Read the signs above or beside the entrance before going through the fare gate.

Look for:

  • The station name
  • Lines served
  • Direction of travel
  • Accessibility symbols
  • Service notices
  • Entrance hours

Paying the Fare

Train and subway systems may accept:

  • Reusable transit cards
  • Paper tickets
  • Mobile tickets
  • Contactless debit or credit cards
  • Digital wallets
  • Cash at a ticket machine
  • Daily, weekly, or monthly passes

Some systems charge a flat fare. Others calculate the fare based on:

  • The distance traveled
  • The number of zones crossed
  • The time of day
  • The type of train
  • Whether the ticket was purchased before boarding
  • Whether the trip is one-way or round-trip

You may need to tap or insert your ticket both when entering and when leaving. Use the same card, ticket, or device for both.

Keep the ticket until your entire trip is complete. A conductor or fare inspector may ask to see it.

Entering Through a Fare Gate

At a fare gate or turnstile:

  1. Have your card, ticket, or device ready.
  2. Tap, swipe, insert, or scan it as directed.
  3. Wait for the acceptance signal.
  4. Walk through promptly.
  5. Collect any ticket returned by the machine.

Do not follow closely behind another passenger or attempt to enter without paying.

If the gate does not open, read the message on the screen. It may say:

  • Insufficient balance
  • Tap again
  • Ticket expired
  • Wrong direction
  • See agent
  • Card not accepted

Ask a transit employee for help if the payment continues to fail.

Checking Departure Boards

Departure boards may display:

  • Train line or number
  • Final destination
  • Departure time
  • Track or platform
  • Expected arrival
  • Delay information
  • Cancellations
  • Boarding status

Confirm all the details instead of checking only the departure time. Several trains may leave within a few minutes of one another.

A track number may not be posted until shortly before departure. Stay near the departure board and continue checking for updates.

Waiting Safely on the Platform

While waiting:

  • Remain behind the marked safety line.
  • Stay away from the platform edge.
  • Keep children and belongings close.
  • Avoid leaning over the tracks.
  • Allow arriving passengers to exit first.
  • Keep walking areas clear.
  • Secure loose items.
  • Remain aware of announcements.
  • Do not enter restricted track areas.

If an item falls onto the tracks, do not retrieve it yourself. Tell a transit employee.

Stand where you can see the train’s route and destination signs as it arrives.

Boarding the Train

Before boarding, confirm:

  • The train line
  • The final destination
  • The direction of travel
  • Whether it is local or express
  • Whether it stops at your destination or transfer station

Allow passengers to exit before you enter.

Once onboard:

  • Move away from the doors.
  • Hold a pole or handrail.
  • Sit when a seat is available.
  • Keep aisles and doors clear.
  • Secure bags and personal belongings.
  • Avoid placing belongings on another seat when the train is crowded.

If you use a mobility device, stroller, or other equipment, position it safely and follow posted instructions.

Following Your Progress

You can track your location by:

  • Watching the onboard route display
  • Listening to stop announcements
  • Looking through the windows for station signs
  • Following the route in a transit app
  • Counting stops
  • Checking a saved route plan
  • Asking the conductor or another employee

Know the station immediately before your destination or transfer point. When the train reaches that station, begin preparing to leave.

Do not rely completely on your phone. Your device could lose service, run out of power, or provide outdated information.

Leaving at the Correct Station

As your stop approaches:

  1. Gather your belongings.
  2. Move toward the door when it is safe.
  3. Check the station name as the train arrives.
  4. Allow the train to stop completely.
  5. Step carefully over the space between the train and platform.
  6. Move away from the door after exiting.

Some train doors close quickly. Do not block or force them open. If you miss your stop, remain calm and get off at the next station.

Finding the Correct Exit

Large stations may have several exits leading to different streets, intersections, buildings, or neighborhoods.

Before leaving the station, look for signs showing:

  • Street names
  • Avenue names
  • Building or landmark names
  • Bus connections
  • Taxi or rideshare areas
  • Elevators
  • Accessible exits
  • Directional arrows

Using the wrong exit may add several blocks of walking or place you on the opposite side of a busy road.

If possible, identify the best exit while planning the trip. A navigation app or station map may show which exit is closest to your destination.

Accessibility Considerations

Not every station or route is equally accessible.

Check whether your trip includes:

  • Elevators
  • Ramps
  • Level boarding
  • Wide fare gates
  • Accessible restrooms
  • Audio announcements
  • Visual displays
  • Tactile platform markings
  • Staff assistance
  • Accessible transfers

An elevator outage can make an otherwise accessible route unusable. Check service alerts before leaving and have an alternative route when possible.

If you need assistance boarding, navigating the station, or using a mobility device, contact the transportation agency before the trip to learn what support is available.

Service Changes and Delays

Train service may be affected by:

  • Maintenance
  • Construction
  • Signal problems
  • Mechanical problems
  • Severe weather
  • Police or emergency activity
  • Staffing issues
  • Special events
  • Track work

These conditions may cause:

  • Delays
  • Canceled trains
  • Different platform assignments
  • Express trains operating locally
  • Local trains skipping stations
  • Replacement bus service
  • Closed entrances or stations
  • Changes to transfer points

Check service alerts before leaving and again during the trip. Pay attention to announcements even if you already know the route.

If You Miss a Transfer

If you miss a connecting train:

  1. Stay calm.
  2. Check when the next train will arrive.
  3. Confirm that you are still on the correct platform.
  4. Look for another route to the destination.
  5. Contact the person or place expecting you if you will be late.
  6. Ask a transit employee for help if the connection was the final train.

On a subway, another train may arrive within a few minutes. On commuter or intercity rail, the wait may be much longer.

Do not rush across a station, run on stairs, or attempt to hold train doors. Arriving safely is more important than making one connection.

If You Board the Wrong Train

If you realize you are traveling in the wrong direction:

  1. Get off at the next safe station.
  2. Follow signs to the opposite-direction platform.
  3. Confirm the line and destination before boarding again.
  4. Check whether another fare is required.
  5. Update your expected arrival time.

If you boarded the correct line but the wrong type of train, such as an express instead of a local, ask a transit employee where to transfer back.

Avoid leaving the station in an unfamiliar area unless you know what to do next.

If You Miss Your Stop

Missing a stop happens to experienced travelers, too.

When it happens:

  1. Leave the train at the next station.
  2. Find the platform for the opposite direction.
  3. Take a train back to your intended stop.
  4. Confirm that the returning train stops there.

Do not panic or try to prevent the doors from closing. A missed stop usually adds time, but it can be corrected safely.

Practice Before an Important Trip

If the route is unfamiliar, consider practicing before using it for an appointment, class, interview, or other time-sensitive event.

You can:

  • Review the route on a map.
  • Visit the starting station.
  • Travel with someone you trust.
  • Practice during daylight.
  • Avoid the busiest travel hours.
  • Photograph useful signs and landmarks.
  • Save screenshots of the route.
  • Write down each train and transfer.
  • Locate the correct return platform.
  • Identify an alternative route.

Some public transportation agencies offer travel training for people who want help learning to use buses, trains, stations, fares, and transfers.

Create a Step-by-Step Trip Plan

A written plan might look like this:

  • Enter Central Station through the Main Street entrance.
  • Take the Blue Line toward Riverside.
  • Ride five stops to Union Square.
  • Transfer to the Green Line toward Oak Park.
  • Ride three stops to Medical Center.
  • Follow signs for the West Avenue exit.
  • Walk one block to 250 West Avenue.
  • Use the Medical Center station’s eastbound platform for the return trip.

Include:

  • Line names or numbers
  • Train directions
  • Transfer stations
  • Number of stops
  • Exit information
  • Expected travel time
  • Fare information
  • Backup routes
  • Customer-service numbers

Keep the plan on paper or save it in your phone.

Final Thoughts

Trains and subways may seem complicated because one trip can involve several lines, platforms, stations, and transfers. You do not need to understand every part of the system before you begin.

Focus on the specific information needed for your trip: your starting station, train line, direction, transfer point, destination station, and exit. Check service alerts, allow extra time, and ask a transit employee when something is unclear.

With preparation and practice, trains and subways can become a dependable way to travel independently, even when your trip requires a transfer.
