Railway Basic Signalling System Solution

System Introduction

In order to meet the needs of customers who construct railway lines with limited investment, HollySys has developed a set of Basic Signalling System (BSS) which conforms to global standards, is safe and reliable, can be deployed quickly with low investment. 

BSS system is composed of Centralized Traffic Control system, interlocking system, train detection system, point machine, signal and maintenance monitoring system, etc. The BSS realizes the functions of centralized dispatching management of trains, safety train operation, signal display & control and maintenance diagnosis. BSS can work independently or as a backup signalling system of more advanced level signalling system. 

BSS system, as a basic signalling system, can be upgraded to other advanced level signalling system easily. It can be used for railway project with construction requirement of gradual upgrade in different phases.

  • Short Construction Period

    Mature solutions and system equipment in a modular and standardized design way, assembly and testing in factory make it easy to be implemented. It is helpful for shortening the construction period.

  • Upgrade Gradually

    After the signalling system is put into operation, it can be seamlessly upgraded to a signalling system with higher automation level by a simple superposition renovation if needed.

  • Low Investment

    Basic signalling control system and high-reliability equipment with maintenance support system can reduce construction and maintenance costs.

  • Customized Service

    The display of HMI (icons, layouts, etc.) and operation manner can be customized according to different national standards, different user requirements and site conditions.
