To read a transport map, locate your origin and destination, then follow the lines that connect them. Identify transfers and the direction for each leg. Then check the schedules: the map shows the network layout but does not guarantee a service will be running when you need it.
Locate lines, stops and termini
Start with the legend. A colour, number or letter may identify a line; symbols can distinguish modes and transfers. Check their meaning on the map you are using.
Then follow the line between stops. Intermediate dots represent places where you can potentially board or alight, subject to the service in question. The end points help identify the direction.
On a large network, first look for the area of your destination. This avoids reading every line before understanding where you need to go.
Find transport stops nearby.
Explore stops listed around a city or your location. Check the details for transport modes and available information.
Understanding a transfer
A transfer lets you change from one line or mode to another. The map symbol indicates a relationship between these services; it does not always show how long the change will take.
In the same location you may need to change platform, exit to the street or use a different entrance. Check the route and ticketing conditions.
Illustrative example: the fictional line A connects Station to Town Hall; line B connects Town Hall to Museum. Your Station–Museum trip has two segments and a transfer at Town Hall. You must choose the correct direction on each of the two lines.
Identify branches and variants
A line can split after a common stop. In that case, the number or letter alone is not enough: the terminating station for that service determines the branch.
If a route appears dashed, check the legend. It may represent a special service, a limited routing or another graphic convention. Do not assign a universal meaning to this symbol.
Our guide to finding the right stop and direction completes this reading.
Distinguish diagram from geographic map
A schematic map simplifies the network to make connections readable. The distances between points do not necessarily represent real distances.
Two stations drawn very close may require a longer walk than expected. Conversely, a transfer can sometimes be avoided by walking between two places that are geographically close.
Use a map to check distance, streets and access. ROOTE can be used to explore stops listed around a place in covered areas. The guide to finding a nearby stop describes useful checks.
Check schedules and the service day
After choosing a route, check the timings for the intended date. Verify each segment and allow time for transfers.
The description of a network and upcoming departures are distinct pieces of information. Separate places, routes, schedules and disruptions to understand what the map tells you.
An old map may miss a line change. Look for the network version that matches your trip and check official alerts.
Frequently asked questions
Does a transfer point mean the change is immediate?
No. Check access routes and the time needed between lines.
Can you estimate a distance from a metro diagram?
Not from a schematic alone. Use a geographic map for walking distances.
Does a line shown on the map run all day?
The map alone is not enough to know. Check the timetables and the service calendar.
