Train Control System Solution for High-speed Railway(up to 250/350km/h)

System Introduction

Continuous transmission of movement authority (MA) from track to train via track circuit, spot transmission of line data, route status and temporary speed restricted information from track to train via balises. Train Control Center generates train operation permission (low frequency information and Temporary Speed Restriction) and send to the on-board equipment through variable balise and frequency shift track circuit. Balises are needed to transfer positioning information, line parameters, speed limit and parking location information to the onboard equipment.

    Safety and Reliability
    • It is based on the principle of fail-safe, conforms to IEEE, IEC, CENELEC standards and national railway standards. The core equipment such as train control center, interlocking, track circuit, on-board ATP, LEU, balise have got SIL4 safety certificates. The control equipment has proven record of reliablity and performs various functions of self-inspection, self-diagnosis and maintenance, which guarantee the safe operation of trains.

  • icon19.svg
    ATO Functions Support
    • The system can be configured with Automatic Train Operation (ATO) (GoA2) equipment in order to realize automatic train operation.

  • icon01.svg
    Transport Efficiency
    • The system can ensure the safe operation of trains at a high speed up to 250km/h, with a minimum 3 minutes train headway and high transport efficiency.
