must be seperate in different fonction with clear names

Exemple

    private function getRailwayDistance(): int
    {
        return ($this->distance
            - $this->getDistanceOf(TrainStation::class)
            - $this->getDistanceOf(PowerBreak::class)
            - $this->getDistanceOf(NaturalIncident::class));
    }
