Key Technology Research on Jointless Track Circuit in High-speed Railway

Track circuit is an important basic equipment in the high-speed railway, which supervises the track occupancy and transmits the train operation information. The mechanical insulation joint in the track circuit limits the train speed and introduces the safety hidden danger. Jointless track circuit adopts electrical tuning unit to replace the mechanical insulation, which realizes the seamless connection of the track. The disconnection of the track circuit is inspected. The jointless track circuit increases the train speed and improves the anti-interference ability.
