Find London areas within walking distance of useful rail lines

A nearby station is useful only if it serves a line that fits your journeys and has an approach you can actually reach. Start with the lines and a realistic walk, rather than drawing the same circle around every station.

notbad estimates walks through its saved network of mapped streets and pedestrian paths. It covers Underground, Overground, DLR and Elizabeth line stations, with all 19 supported line IDs selected initially. Jubilee is one of the Underground lines, not a separate transport network.

Choose useful lines before tightening the walk

Select one or more lines and set a maximum walk between 1 and 30 minutes. With the ordinary station condition, any selected line can qualify. Selecting several useful lines expands the possible station destinations within that one condition; it does not require a nearby station for every line.

All matching stations together still contribute one criterion. The map then intersects station access with every other enabled condition, such as parks or noise exclusions.

If you clear every line, the station condition becomes unknown. The app asks you to select a line instead of treating an empty choice as successful access.

Use backup access when two lines matter

The optional backup requirement asks for two different selected lines. You can set a primary walking limit and a separate backup limit. One interchange station can satisfy both when it serves the two lines.

For example, you might accept a shorter walk to your usual line and a longer walk to an alternative. The budgets express your preference; they are not an assessment of service quality, frequency or disruption risk.

Two stations on the same line do not meet the distinct-line requirement. Two useful lines still count as one station-access condition, not two independent recommendation points.

Why a walking area is not a radius

The estimate follows mapped connected streets and paths at an assumed pace of 80 metres per minute. Railways, waterways, fences, crossings and available connections can change the useful area around a station. A place that looks close in a straight line may need a longer route.

Station approaches prefer mapped entrances. Where those are unavailable, an approximate station-position approach may be used and labelled. The starting location is also an estimate of its surroundings rather than a surveyed front-door route.

Missing connections remain unknown. An unmapped route does not prove that a real route is impossible, and a mapped connection is not a promise that an entrance is currently open.

Keep the whole journey in view

The displayed minutes describe walking access to a mapped station approach. They do not include waiting, the train journey, a transfer or the walk at the other end. The app is not a live journey planner.

Check the full journey separately for your actual destination and time. Walk the local approach when considering a home, and check current station information. The saved walking data does not provide wheelchair or step-free routing, opening-hours checks or temporary-closure information.

Use the map and postcode report for different questions

Use Explore to find areas that meet your chosen lines and walking budgets. Use Check a postcode to inspect a place you have already found: its independent report searches all supported lines, without the backup requirement, up to the existing 30-minute cap.

That difference is deliberate. One mode applies your preferences to a search; the other describes the mapped evidence around a representative location.

Check which rail services the tool covers

The Ealing examples point towards different supported stations; the Havering page compares Upminster and Romford approaches. By contrast, the Bexley samples do not supply a supported-line walk within the report's limits. This tool covers Underground, Overground, DLR and Elizabeth lines, not every National Rail service. A missing supported-line result is therefore not proof of no railway connection. The table below uses the same all-line, 30-minute report profile for each public reference point.
