Why This Calculator is Useful

London’s Underground network—also known as “the Tube”—is one of the busiest and most complex transit systems in the world. With 11 lines and 270 stations, it can be confusing for newcomers and even regular commuters to plan the most efficient route.

This calculator simplifies the process by:

• Showing which line(s) are involved in your journey.
• Providing an estimated travel time.
• Indicating if a line transfer is required.
• Offering an easy-to-use interface without needing apps or maps.

FAQ – London Underground Line Calculator

Q1: How accurate are the travel times?
A: The times are estimates and vary depending on delays, waiting for trains, and walking between platforms. It gives a ballpark figure rather than exact timings.

Q2: Does this calculator include station walking times or escalators?
A: No, it assumes only travel on trains. Walking times inside large stations (like King’s Cross) can add several minutes.

Q3: Can I calculate journeys with multiple transfers?
A: This version calculates one transfer maximum. A future version could support multiple changes across different lines.

Q4: Does it cover all 270 Underground stations?
A: No, this demo uses a smaller set of popular stations. It can be expanded to include the full London Underground map.

Q5: Can it help me calculate fares?
A: Not yet. This calculator focuses only on journey times and lines. For fares, you’d need Transport for London’s (TfL) official fare calculator.

Q6: Is this calculator a replacement for apps like Citymapper or TfL Journey Planner?
A: No, it’s a simplified educational tool. For real-time updates, delays, and detailed routing, official apps should be used.
