Real-time railway traffic control system was implemented into industrial operation at Oktyabrskaya Railway Board (Russian Railways JSC )

In December 2014, Unified Intelligent Railway Transport Control System was implemented into industrial operation for Oktyabrskaya Railway directions Moscow-Saint-Petersburg and Saint-Petersburg-Buslovskaya.

NIIAS JSC, a parent organization for automation of operational procedures of "Russian Railways JSC, started implementation of the Unified Intelligent Railway Transport Control System in 2012.

Unified Intelligent Railway Transport Control System is a hardware-in-the-loop platform and information space for development of functional and technological subsystems for controlling different areas of railway operational procedures.

Software Engineering Company Smart Solutions has developed one of the most important components of the System the real-time railway traffic control module.

The module provides for scheduling trains routes taking into account various criteria and limitations such as train dimensions, tonnage rating, travel time norms, acceleration and braking time, safety standards and so on. 

In railway traffic control specialists face many unforeseen events that can lead to timetable deviations of passenger, commuter, freight trains, especially in such large-scale railway systems as the Oktyabrskaya Railway.

Complexity of traffic control in such railway systems is caused by the following factors:      

  • a large number of elements;

  • high intensity and speed of the trains;

  • a high degree of train coherence: changes in the trains schedule or a conflict affecting the train will definitely impact the next train, and very likely can spread throughout the whole railway network in a chain reaction.

It becomes impossible to ensure effective planning of railway traffic manually, when a dispatcher has only five minutes to make a decision in case of an emergency.

The developed module provides the ability to manage railway traffic and train routes efficiently in real time. taking into account emergencies (train schedule leads and lags, breakage of railway tracks, trains or other infrastructure facilities, track occupancy, etc.). The module forms recommendations for dispatcher railway regulation.

The system has been refined according to dispatchers comments during six months of pilot operation. During this period, the number of planning criteria (conditions and limitations) has increased by 5 times: from 10 to 50!
