Hysteresis is basically saying something like "I want 50 gears, but once I get 50 gears, I don't want any gears until the number I have at the station drops below 20".
Even though we're not paying for fuel, a train journey still has costs (the train's time, as well as blocking the track segments it passes through).
There are multiple train journeys that could just be one quite frequently because goods are delivered to the stations by beavers who have a lower carry capacity than train wagons.
