Abstract
A tank drainage device for a fresh water tank on a rail vehicle includes a thermostatic switch disposed on a drainage line and thermally coupled to the fresh water. In the event of the temperature in the tank falling below a predefined temperature, the thermostatic switch triggers a timing element which thereby opens a drainage valve for a predefined period.
