Live Speed Monitoring

Unlike a single speed test that captures one moment, continuous speed monitoring gives you the full picture of your journey. The monitor takes a GPS reading every second, calculates your instantaneous velocity, and plots it on a live-updating dashboard. You can watch your train accelerate out of a station, cruise at top speed between stops, and brake on approach — all rendered as a smooth, scrolling speed graph. This continuous feed reveals patterns a snapshot never could: speed restrictions through junctions, the difference between express and stopping services, and exactly how long your train holds its peak speed.

Continuous GPS Feed

The monitor polls your device's GPS every second, providing a smooth and responsive speed reading that captures every change in velocity as it happens.

Live Dashboard View

A real-time speedometer dial and scrolling speed graph give you an at-a-glance view of current speed, peak speed, and average speed throughout the monitoring session.

Monitor Your Journey

The journey monitoring feature goes beyond raw speed numbers. It detects your peak speed automatically and timestamps it so you know exactly when and where your train was fastest. Speed zone detection identifies when the train enters restricted-speed areas — such as station approaches, curves, or construction zones — and highlights them on your timeline. You can set custom notifications to alert you when a speed threshold is crossed, whether you want to know when the train exceeds 200 km/h on a high-speed line or drops below 50 km/h in an urban section. The complete journey profile can be reviewed after your trip to compare routes or services.

Peak Speed Detection

Automatically identifies and timestamps the highest speed reached during your journey, so you can pinpoint exactly when and where the train was at its fastest.

Speed Zone Alerts

Set custom speed thresholds and receive instant notifications when the train crosses them — ideal for tracking high-speed sections or spotting slowdowns.

Journey Timeline

Review a complete speed-over-time profile after your trip. Compare different services, routes, or days to see which journeys are consistently faster.
