ETCS Level 2 is a radio based train control system with an underlying signalling system. It is based on continuous bi-directional wireless data communication between the Radio Block Center (RBC) and the trains, balises are equipped mainly for location referencing. HollySys has got Baseline-3 (B3R2) TSI Certificate for RBC and on-board train control system. ERTMS/ETCS level 2 solution provided by HollySys includes Centralized Traffic Control system, Intelligent Maintenance System and ETCS level 2. It can be equipped with distributed Computer Based Interlocking or Solid Static Interlocking systems. Addition to conventional solutions, system achieves a remote control of trackside equipment and the intelligent maintenance for signalling facilities.
Train speed and the target-distance are controlled through onboard-trackside bi-directional transmissions of real-time data.
The system can be tailored flexibly according to existing national system and user requirements. Trackside controlling equipment could be flexibly deployed indoors or outdoors, wired or wireless to match the site conditions. Lineside signals and object controller are optionals and can be suppressed if necessary.
Supports the interoperability between ETCS level 2 railway lines and supports operation in degrade level.
The Center system integrates the functions of dispatching and maintenance. The trackside object controller equipment integrates the functions of control and acquisition, it is also equipped with both wired and wireless modules.
