Frequently asked questions
What is the Tube status widget?
It is a small, self-contained panel that shows the live status of every London Underground, Overground, Elizabeth line, DLR, and Tram service. You can embed it on your website or intranet as a live iframe (updates every 60 seconds, interactive with clickable links) or as a static image badge (updates every 15 minutes, works anywhere images are supported). Both formats use data from the TfL API.
Is the widget really free?
Yes - completely free, no account required, no usage limits, no ads. We built it because TfL's own embeddable widget was discontinued and we wanted to offer a replacement for the community.
Do I need any coding skills to add it?
No. Enter your domain above, click Generate, and copy the snippet into your site's HTML. For the live iframe, it is a standard iframe tag that most website builders support (WordPress, Squarespace, Wix, Notion, Confluence). For the image badge, it is a simple img tag that works anywhere images are accepted.
Who uses this widget?
Office reception screens and corporate lobbies showing live transport status for visitors and staff. Company intranets and internal dashboards so employees can check before leaving for the day. Coworking spaces and serviced offices that want to display useful London travel information. Property and estate agency websites adding value for prospective tenants near Tube stations. Travel blogs and London guide sites giving readers real-time service information. University and school portals helping students plan their commute.
How does the widget look on my site?
The widget has a clean, modern design with the official TfL colour for each line, clear status labels, and a compact layout that fits neatly in a sidebar or content area. It adapts to its container width. When all lines are running well, good-service lines are shown in a neat colour grid. When there are disruptions, affected lines appear at the top with their status highlighted.
How often does the data update?
Status data is fetched from the TfL Unified API every 60 seconds on our servers. The widget in your page refreshes automatically on the same cycle - no page reload needed. A green indicator dot in the header shows the widget is live.
Will the widget slow down my website?
No. The widget loads inside an iframe so it is completely isolated from your page. It has no external dependencies (all CSS is inline, no JavaScript libraries), weighs under 10 KB, and makes one small API call every 60 seconds. It uses the loading="lazy" attribute so it only loads when the user scrolls it into view.
Can I customise the size?
You can set any width and height in the embed code. The widget is responsive and adapts to its container. We suggest 240-350 px for sidebars and 350-600 px for wider placements. Height adjusts automatically based on how many lines are disrupted.
What is the difference between the live iframe and the image badge?
The live iframe is the recommended option for most websites. It updates every 60 seconds, has clickable links to each line's status page, and requires no page reloads. The image badge is a static SVG image that updates every 15 minutes. It works in places where iframes are not supported - GitHub READMEs, Notion pages, email signatures, Markdown documents, and any platform that accepts image URLs. Choose the iframe for your website; choose the image badge when you need an image.
How do I add the image badge to my site?
Select "Image badge" in the widget format option, then copy the generated code. It is a standard img tag wrapped in a link. For HTML pages, paste it directly. For GitHub READMEs or Markdown, use: . For Notion, paste the image URL into an embed block. The image refreshes every 15 minutes via the browser cache.
Can I show only specific lines?
Yes. Click "Customise lines" on the generator above to select exactly which lines you want to display. Your selection applies to both the live iframe and the image badge. This is useful if you only need to show lines relevant to your area, such as the Central and Jubilee lines for Stratford.
Where does the data come from?
All status information comes from the TfL Unified API, the same open data source that powers TfL's own website and apps. We poll it every 60 seconds. The widget covers the Bakerloo, Central, Circle, District, Hammersmith and City, Jubilee, Metropolitan, Northern, Piccadilly, Victoria, Waterloo and City, Elizabeth line, DLR, Tram, and all six London Overground lines (Liberty, Lioness, Mildmay, Suffragette, Weaver, Windrush).
