Abstract
A signal-controlled crew warning system for warning people of approaching rail vehicles on an operational track located in a warning sector of a work track. The warning system includes a track-building machine for working on the work track, a positioning system for determining the position of the track-building machine, a computer-aided monitoring system for generating warning information, warning measures for generating acoustic or optical or haptic warning signals, and a radio system for wireless data transfer. The computer-aided monitoring system is configured to set boundaries of the warning sector on a basis of the current position of the track-building machine and to automatically generate warning information for the warning sector. The track-building machine has a central control unit for processing the warning information, which control unit is coupled to the computer-aided monitoring system via the radio system. The warning sector thus moves along with the track-building machine as it travels.
