Krois-Modell 6057, Train preheating system, H0 gauge

An electric train preheating system is a stationary device that is used to supply parked trains or carriages with electricity at the voltage of the train busbar (in Germany, Austria and Switzerland: 1000 V 16.7 Hz alternating current, single-phase) without the need for a traction vehicle.

This device is mainly used to preheat or air-condition parked carriages so that they are available at the right temperature for the next use. If trains are parked for a longer period in winter, such as over a weekend, the control of the train preheating system ensures that the temperature in the carriages does not fall below freezing and keeps it constant at around 5 °C. If it is not possible to guarantee that there will be no frost, the vehicles would have to be drained and refilled before the next use.

In modern carriages, the vehicle batteries are no longer charged by an axle generator, but by a charger from the train busbar. Because of the power supply when stationary, such vehicles only have about half the battery capacity of comparable cars with generator power. These cars must be connected to the train preheating system when parked for a long time, otherwise permanent consumers will discharge the battery.
