Hitachi's totally digital solution secures on-track safety across Britain's rail network, operating in parallel with existing processes and requires no lineside hardware

Railway Signalling Safety

TREsa Hitachi’s Signallers Assistant delivers rail services against the timetable, allowing Signallers to concentrate on incidents and other emerging situations. Fully ARS+ compliant; TREsa is installed at a number of signalling centres and rail operating centres in the UK where it assists Signallers in the safe and efficient running of the railway.

The railway safety system aims to reduce Signaller workload demand by automatically routing trains based on timetable and infrastructure data. Thereby Hitachi's solutions improve a Signaller's ability to supervise the efficient running of a signalling area and enabling them to concentrate on incident management when required for improved railway safety.

Trackworker Protection

It’s claimed that the UK railway is amongst the safest in Europe but with near misses continuing to happen, a good safety rating isn't good enough. Maintenance workers operating in the trackside environment often conduct activities that require concentration and focus. Being confident that the right protection is in place before and during their work is paramount for trackworker safety.

Despite a well-defined Safe System of Work (SSoW) process where activities are planned, and safety briefings are given before any trackside work starts, too often trackside workers report near misses due to reduced situational awareness.

Our solution to poor trackside safety is Trackside Guardian (TSG).

Trackside Guardian (TSG)

With no trackside hardware to install, Trackside Guardian is simple to deploy and is compatible with any signalling system while also complementing all existing operational procedures.

How it works:

TSG monitors signalling states in conjunction with requested lockout areas to ensure that all the necessary restrictions have been applied before a Signaller grants a Line Block, thereby providing assurance to the trackworker that sufficient protection is in place for improved trackside safety.

To combat the hazard of reduced situational awareness, TSG also sends both the Signaller and the Controller of Site Safety (CoSS) an alert informing them of approaching trains on any lines adjacent to their worksite. This improves rail safety as situational awareness is assured. 

To further railway safety, the system prevents trains being inadvertently routed into line blockages. It ensures that the necessary protection remains in place by monitoring and filtering out unsafe commands between the signalling control system and the interlocking.
