Driver cost

What this is

What the drivers cost over a year.

Paid hours exceed hours on the train. A driver signs on before departure, signs off after arrival, travels to and from the train, rests away from home base, and has to be covered by a reserve. The model prices this through a roster efficiency: the share of paid hours that is productive.

That share is not constant. A shift may not exceed a legal maximum, so a long trip has to be split, and every additional shift boundary adds a fixed allowance.

What the drivers cost per year, including the relief driver a long trip needs.

The formula

$$C_{driver} = \frac{c_{driver/h}}{\eta_{driver}} \times \left( \sum_{seg} t_{seg,h} \cdot f_{driver} + \sum_{stop} t_{dwell,h} \cdot f_{driver} \right)$$
