Computer-based semi-automatic block signalling ImProTRACK SAB
ImProTRACK SAB is a system for train separation and ensuring the safety of train traffic on single-track and multi-track low-traffic railway open tracks with different types of traction using the semi-automatic block signalling function.
Control of occupancy/vacancy of an open track is carried out using axle counting equipment. There is an option to organize automatic checkpoints on the open track to increase the train capacity. ImProTRACK SAB has both digital and relay-and-contact interfaces for coupling with any type of electrical interlocking.
Main functions

Control of occupancy/vacancy of each track of an open track.

Automatic control of complete train arrival.

Sharing information between adjacent stations
for implementation of semi-automatic block signalling algorithm.

Coding of track circuits of station
approach sections by ALS signals.
System advantages

Minimum quantity of station equipment
when integrating into ImProTRACK

Software implementation of logical dependencies
in a safe central processor
Possibility to arrange an automatic checkpoint on an open track.
