ARS
Automatic Route Setting System

Introduction
ARS is a highly versatile subsystem of DeltaRail's Integrated Electronic Control Centre (IECC®).  It is capable of automatically performing many of the standard activities undertaken by signallers and is now installed at 12 signalling centres throughout the UK.

ARS has been demonstrated under simulation as being compatible with ERTMS and work is continuing to further develop this capability.  Development is ongoing to transfer the ARS system onto a PC-based hardware platform.

Key Features
• The advanced decision-making strategies in ARS ensure that optimal routing decisions can be made, even under disrupted conditions.

• ARS is typically implemented as an integral part of IECC®, but can also been implemented as a standalone system.

• Maintenance of timetabled junction sequences when all trains are running to time.

• Prioritising train routing at times of perturbation to minimise train delays.

• Alternative routing strategies to deal with slower trains ahead, revised platform arrangements and/ or equipment failures.

• Conditional route setting away from stations based upon booked departure times, connections and train ready to start indications.

• Manual control of specific sub-areas of the overall area controlled by ARS while maintaining automatic routesetting operation elsewhere.

• Capability to run trains not included in the timetable to special timing patterns.

• ARS monitors the signalling area to provide the signaller with warnings and alarms including SPAD alarms, train delays in signalling sections, unexpected occupations, arrival of specific classes of train.

• The signaller can request ARS to provide information on route setting status of any train.

• ARS is able to interpose the outward working headcode for any train scheduled to turn around.

Benefits
• Improved train punctuality and faster recovery from perturbations.

• Greater routeing flexibility.

• Optimisation of operating expenditure through increased signaller productivity.
