The train detection system ZEUS-300 FTGK is a track vacancy detection system based on remotely fed audio frequency track circuits. It can however also be implemented as directly fed audio frequency track circuit in the variant OTGK. ZEUS-300 can be used as block section or point safety system both in subway and surface rail systems up to AK7 or ...

A common operational scenario can summarize the track circuit operation: if a train A attempts to approach too close to the rear of the next train B, the locations information provided by the track circuits is used to command a speed reduction or a trip of the train A, avoiding a possible collision. Halo Track System (HT) The HT system is known as 3-wire single circuit systems and is the most popular track system on the market today. HT compatible system is available at most home improvement centers. If you look at the track, then there should be 2 strip of wire on one side and 1 strip of wire on the other side.

The MICROTRAX Coded Track Circuit is a solid-state, microprocessor-based track and line circuit system designed to work in non-electrified territory. It combines the functions of train detection and line wire circuitry, with all communications carried through the rails. Vital integrity is maintained

types of track circuits, it must first be considered how track circuits are used in the operation of a transit system. A track circuit provides information on whether a train occupies a given length of track (a block). The occupancy information for a particu-lar block and for contiguous upstream of blocks is The MICROTRAX Coded Track Circuit is a solid-state, microprocessor-based track and line circuit system designed to work in non-electrified territory. It combines the functions of train detection and line wire circuitry, with all communications carried through the rails. Vital integrity is maintained

7.3.2 Track Circuit Operation A battery is connected to one end of the track circuit, close to the insulated joints, with positive energy applied to the south rail fiSfl and negative to the north rail fiN.fl The relay is connected at the other end of the track circuit with one lead of the relay coils Sep 30, 2019 · A track circuit forms part of the broader signalling system, which comprises many parts to enable trains to move safely around the network. A track circuit itself is an electrical system that detects the absence of a train on a section of track. This information then helps the signalling system know if it’s safe for another train to proceed.
