eng.train-braking-distance Calculator
Calculates train stopping distance from initial speed, braking rate, reaction time, and grade factor. Train stopping distances are much longer than road vehicles — a freight train at 60 mph requires 1–2 km to stop, compared to 100m for a car.
Inputs
Train Speed Kmh
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
Deceleration M S2
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Reaction Time S
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Grade Pct
Reference formula or conversion factor shown for context.
Results
total braking distance (m)
The computed distance or separation.
braking distance (m)
The computed distance or separation.
reaction distance (m)
The computed distance or separation.
effective deceleration (m/s²)
The proportional relationship between two quantities.
v²/(2a) + v·t
Reference formula or conversion factor shown for context.
HSR: 350 km/h
Reference formula or conversion factor shown for context.
