About London Underground Alerter

Who we are

London Underground Alerter - Tube Alerter for short - is a London transport data site based in Hackney, built by John C., a transport data analyst, with a small team of contributors. We build alerts, trackers, dashboards, and explainers to make London's transport network easier to follow and understand.

Why Tube Alerter is different

Our goal is to send you as few alerts as possible. Nobody likes being bombarded with notifications, so we have gone out of our way to give you control over exactly when, how, and why you hear from us. Most services tell you the network is having a bad day. Tube Alerter tells you when your commute is affected - and stays quiet the rest of the time.

We wanted to build something that just works. No app to install, no settings buried three menus deep. Set it up once and forget about it until it matters.

Your alerts, your rules

• Route filters: narrow alerts to just the section of a line you travel on. Set a route filter and you will only hear about disruptions that affect your specific stretch.
• Severity filters: only care about serious disruptions? Turn off Minor Delays and we will only alert you when it really matters.
• Custom time windows: set one or more alert windows that match your actual schedule, not a fixed rush-hour slot.
• Pick your days: choose which days you travel - most people skip weekends, but shift workers can select any combination.
• Skip bank holidays: one toggle and you will not hear from us on public holidays.
• Pause from your inbox: having a noisy day on the network? Hit "Pause for today" in any alert email to silence notifications for the rest of the day. Going on holiday? Pause for up to two weeks from your manage page.
• Sensible behaviour: alerts escalate with worsening disruptions and never repeat for the same issue. Opt into recovery emails to know when things are back to normal.

Email-first, with push if you want it

• No app to install, no account to create. Set it up once and forget about it.
• Alerts arrive in your inbox - often easier to spot than a buried push notification when you are in a rush.
• Want real-time push notifications instead? Enable them from the site - no app download needed.
• Every email has links to manage your settings, pause alerts, or unsubscribe. No hoops.

Accessibility support that is proactive

• Step-free station lift alerts: get notified when lifts go out (and optionally when they are back), tuned to reduce false alarms.
• Station closure alerts: get alerts when your stations are closed or have restricted access.

Beyond alerts

Tube Alerter also tracks and publishes live and historical transport data across the network.

• Network Dashboard: live reliability rankings, line-by-line performance, and historical trends across every Tube, Overground, DLR, and Elizabeth line route.
• Insights: data-led articles and explainers covering fares, service patterns, and how the network actually performs.
• Station Closures: live tracker for closed or part-closed stations.
• Mind the Map: a daily geography game - guess where London stations are on a blank map.
