Portable Train Detection & Alarm system is used for protecting workers engaged in work on the railway track, to eliminate the human observer and the associated shortcomings.

Approaching trains are detected by automatic sensing Devices (LIDAR) on either end of the railway line in which work is carried out and signals are transmitted to the central receiving Hooter Device to produce an alarm signal.

The portable central receiving Hooter Device and two portable sensing Devices are wirelessly contact.
