Seoul Metro published data · Lines 1–8
Find Seoul subway distance & travel time
Choose an origin and destination on the same line to see the cumulative-distance difference and the sum of published segment times. This is a reference based on the source’s line order, not live directions or a transfer route.

A “record position” suffix identifies a station name that appears more than once in the source. Before travelling, check the direction and destination as well.
How to use Seoul subway distance and travel-time data
This guide explains what the numbers above mean, what they do not include, and how to turn a published station-to-station reference into a realistic plan.
Read the result as a same-line reference
The finder works with the source’s recorded order on one line. The distance is calculated from the difference between the two cumulative-distance values, while the displayed time is the sum of every published segment time between the selected records. It is useful when you want to know how many railway segments separate two stations or compare two same-line journeys before leaving.
The result is not a door-to-door prediction. It does not include walking from the street to the platform, waiting for the train, changing platforms, leaving through a gate, or walking from the destination station to your final address. Use it as the rail portion of a wider plan.
Published standard time is different from live arrival time
Seoul Metro’s source describes a standard running time for a train between neighbouring stations. A train can still take longer in practice because of passenger boarding, crowding, dwell time, operating adjustments, safety checks, weather, or an event near a station.
If a meeting, flight, medical appointment, or last-train transfer matters, add a margin rather than treating the sum as an exact promise. Check the platform display for the next train and destination, then compare a live map for the current route.
Why line order and direction matter
A station name can appear more than once in the published records, especially where a line has a loop or branch. The finder labels repeated names by record position so that the calculation remains tied to a precise place in the original file. Select the station record and direction carefully instead of relying on the station name alone.
The reverse trip uses the same connected segments as a reference, but practical conditions may differ. Train destinations, turn-backs, waiting time, and service changes can make one direction less convenient at a particular moment.
A practical departure checklist
First choose the same line and the two station records. Next, add the published segment total to your expected platform walk and train wait. Then leave additional time for peak-hour crowding, luggage, children, mobility needs, or a transfer. Finally, confirm the next station and train destination on the platform before boarding.
For a trip across lines, calculate each same-line part separately and use a real-time route planner for the transfer. The published file covers Lines 1–8 only; it should not be used to infer a missing Line 9 segment or a route operated by another service.
Frequently asked questions
Is this a real-time journey planner?
No. It is a reference based on published station distance and standard segment-time records. Use a live route planner and official notices for current service.
Why is the displayed time shorter than my actual trip?
The calculation excludes waiting, walking inside the station, crowding, transfers, and exits. These are often the largest parts of a real passenger journey.
Can I use this for Line 9?
No. The cited station-distance source explicitly provides Lines 1–8, so this page does not estimate Line 9.
