Title: Warning system for trains
Inventor: ROBERT WHITE
IPC: B61L27/00
Filed: 2017-04-27
Abstract: A manually-operable mobile terminal transmits, to a control centre, coordinates of a location and a type and/or severity of risk existing there. The control centre then identifies all trains within a defined region around the identified location. Trains within this region are identified as moving either towards or away from the location and, if the risk is identified as critical, an alert signal is sent only to those trains moving towards the location. This signal may be sent continuously to a train, and the train may in response continuously emit an unmutable warning message to the driver until the train has passed the location. The control centre may also transmit to the mobile terminal a message indicating the number, and expected arrival time, of trains moving towards the location. The coordinates associated with the location may be locked, or may continuously update according to the location of the mobile terminal.
