Subway Travel Time Calculator

How to use Subway Travel Time Calculator

Start with a live map's subway duration, add per-transfer, station-access, exit, and personal buffers, then subtract the total from a desired arrival time.

The tool does not query routes, trains, delays, or last services. You provide the map time and must recheck live routing and operator notices before leaving.

• Use a live map to obtain the current route duration and transfer count.
• Enter route time, buffer per transfer, combined station access and exit time, extra buffer, and desired arrival time.
• Review planned total and departure time, then recheck delays, works, lifts, platforms, and last-train information live.

Useful for

• Work backward from an appointment to choose a time to leave home.
• Explicitly include extra time for luggage, a stroller, lifts, or an unfamiliar interchange.

Limits and checks

• Transfer allowance equals transfer count times minutes per transfer; increase it for long interchanges, luggage, or accessibility needs.
• Treat station access and exit as the combined time from the origin to the platform and from the final platform to the destination.

Worked example

Plan for an 18:00 arrival

Map route: 42 minutes; transfers: 2; 5 minutes each; station access and exit: 12; extra: 10; arrival: 18:00

Origin and destination are labels; route time is not fetched automatically.

Worked departure result

Planned total: 74 minutes; recommended departure: 16:46; calculation: 42 + (2×5) + 12 + 10 = 74

This same-day example contains no live delay or service-availability data.

Common issues

Walking already included by the map was added again as station access time.

Check the map duration's scope and exclude any walking or access segment that it already contains.

The calculated departure was treated as confirmed last-train information.

This tool only adds time. Check last service, delays, works, and operating changes with the live map or operator.

How to interpret the result

The recommendation is only the sum of supplied buffers, so adjust it for congestion, unfamiliar stations, and accessibility needs.

Related workflow

Immediately before departure, recheck live arrival predictions and consult the operator for last services or disruptions.

FAQ

Do origin and destination names trigger an automatic route search?

No. They are labels for the result. You must enter the live map duration and transfer count yourself.

Can the calculated departure fall on the previous date?

Yes, subtraction can cross midnight. That does not prove that a train operates then, so check the actual timetable and last service separately.
