Acceleration
This page is about the acceleration of wagons. Braking is also considered as a type of acceleration.
Acceleration value
The acceleration of each wagon is based on the type of the wagon:
| Type of acceleration (lever) | Acceleration value | ||
|---|---|---|---|
| Per wagon | Per engine | ||
| Emergency brake | BB | -10 | 0 |
| Normal brake | B | -3 | 0 |
| Roll | - | -0.5 | 0 |
| Neutral | o | 0 | 0 |
| Acceleration | + | 0.5 | 1.5 |
The acceleration of the whole train can be calculated using:
Acceleration of each wagon * Number of wagons + Acceleration of each engine * Number of engines
a = ———————————————————————————————————————————————————————————————————————————————————————————————
Number of wagons
Number of engines
= Acceleration of each wagon + Acceleration of each engine * —————————————————
Number of wagons
Time needed for acceleration
The time needed to accelerate from v0 to v1 can be calculated as follows:
v1 - v0
t = ———————
a
Distance needed for acceleration
The distance needed to accelerate from v0 to v1 can be calculated as follows:
a
s = v0 * t + — * t^2
2
v1 - v0 a / v1 - v0 \ 2
= v0 * ——————— + — * | ——————— |
a 2 \ a /
v1^2 - v0^2
= ———————————
2*a
