Abstract
A method for displaying secondary signal devices for a driver of a railway vehicle during a journey by a railway vehicle. From a current vehicle position of the railway vehicle and an already known signal position of a secondary signal device, an actual distance of the railway vehicle in relation to the secondary signal device is determined. In the case that the actual distance is not reached in respect of a predefined current warning distance of the railway vehicle relative to the secondary signal device, a proximity of the railway vehicle relative to the secondary signal device is displayed to the driver.
