Train Acceleration Time Calculator
Train Acceleration Time Calculator
Planning schedules or evaluating rolling stock performance? This calculator estimates time and distance to reach a target speed.
Time = Target Speed(m/s) / Acceleration(m/s┬▓)
Distance = 0.5 x Acceleration x Time┬▓
Example
Accelerating to 100 km/h at 0.6 m/s┬▓:
Time = 27.78 / 0.6 = ~46 seconds (643 m distance)
Why Trains Accelerate So Gently Compared to Cars
Typical passenger train acceleration rates commonly range around 0.5-1.0 m/s┬▓, noticeably gentler than automotive acceleration - this is both for the comfort and safety of standing passengers in aisles, and to stay within the physical wheel-rail adhesion limits that govern how much force can be transmitted to the rail without wheel slip.
Why Distance Matters for Schedule Planning
This acceleration distance directly affects how closely stations can be spaced while still allowing a train to reach reasonable cruising speed between stops - very closely spaced stations limit the benefit of a train's top speed capability since it spends most of the segment still accelerating or braking.
