Minimise Rail Network Delays and Costs with Junction Scheduler

A TTG Energymiser® module, Junction Scheduler works in trains fitted with C-DAS or similar solutions to provide rail traffic management functionality.

Junction Scheduler automatically re-plans train movements through junctions to minimise delays at an individual junction, or a network of junctions. It does this by resolving conflicts automatically in real-time, while also considering energy use – important for congested rail networks. Junction Scheduler also helps produce significant improvements to on-time running and reduces costs due to better scheduled, smoother train flows and on-time arrivals. It also decreases energy use as train stoppages and start-ups are minimised. Asset wear and tear is also reduced by minimising the amount of braking required.


Monitor trains and junctions in real-time

Junction Scheduler plans a sensible arrival time at the junction for each train.

The arrival times allocated to trains are calculated to ensure that trains approaching the junction are spaced with appropriate headways. This means that the likelihood of trains encountering restrictive signals is reduced or eliminated. Junction Scheduler has been successfully used at a Heathrow Airport junction and showed that 75% of delays could be avoided.Junction Scheduler monitors the trains approaching a junction and for each train: – Determines achievable arrival times. – Allocates junction occupancy intervals. – Calculates revised arrival times, and – Sends updated arrival times to DAS-equipped trains. Trains equipped with DAS can then adjust their speed and driving modes, so they arrive at junctions at the adjusted times.


Gain rail network insights with business intelligence

Junction Scheduler generates precise train running data and has a user interface and web-based reporting function.

This data can then be used for timetable performance analysis and improvements. Junction Scheduler can also integrate with other business intelligence systems. Operators can calculate savings based on train stoppage reductions and have this extrapolated to consider cost delays, fines and other KPIs.
