About Train Speed Test

Welcome to Train Speed Test — a simple, free tool for measuring how fast your train is moving in real time. Whether you're a curious commuter, a railfan logging top speeds on a high-speed line, or a student learning about motion and GPS, our speedometer gives you accurate readings right in your browser.

Our mission is to make GPS speed measurement as easy as opening a webpage: no app store, no account, no tracking. Just press Start and watch your speed.

What You Can Do

Privacy First

All GPS data stays on your device. We never store or transmit your coordinates, and the entire speedometer runs locally in your browser. See our Privacy Policy for details.
