A toilet device for a rail vehicle includes flushing water-carrying installations and wastewater-carrying installations. The flushing water-carrying installations include an intermediate reservoir for storing flushing water and a supply line for supplying the intermediate reservoir with flushing water. The supply line includes a filter for filtering the flushing water supplied to the intermediate reservoir. The supply line is connected to the intermediate reservoir such that flushing water from the intermediate reservoir can be returned through the filter. A backflushing line is connected to the filter and opens into a wastewater-carrying installation. A method for operating the toilet device includes supplying the flushing water through a filter to fill the intermediate reservoir, and flushing a flushable bowl with flushing water from the intermediate reservoir or backflushing the filter with flushing water from the intermediate reservoir and draining off the flushing water to a wastewater-carrying installation.

A device for dispensing a predetermined, heated amount of liquid at a removal station. The latter has a liquid reservoir, a supply line from the liquid reservoir to the removal station, and an operating device for triggering a liquid removal. The supply line is adapted to the predetermined amount of liquid in regard to the internal volume of the supply line and the supply line is equipped with a heating device over the length of the supply line.
