Work out train journey time instantly with clear inputs, formula shown and shareable results.
Journey time is running time plus dwell at each stop plus an acceleration and braking penalty of roughly 90 seconds per additional stop. That penalty is why a semi-fast service with six stops takes far longer than the dwell time alone suggests.
Train journey time
total = distance / speed + stops x dwell + stops x acceleration penalty
The time lost decelerating from and accelerating back to line speed. It is typically 60-120 seconds per stop depending on line speed and traction.
Higher line speed means more time lost. A stop on a 200 km/h line can cost three minutes against ninety seconds on a 100 km/h line.
