Gautrain Management System

Read the success story below

Gautrain infrastructure running on rails with help from AVEVA (formerly Wonderware)

With trains running at 97% punctuality and 100% availability from Day 1, Gautrain has set enviable standards for the South African transportation industry. During the Football World Cup, Gautrain exceeded all expectations by ferrying well over 100 000 passengers and on 22nd September 2010, the rapid-rail system celebrated carrying its one-millionth train passenger

Behind the scenes of this impressive achievement, is a Station and Tunnel Management System (STMS) based on AVEVA Technology from IS³ (formerly Wonderware Southern Africa) and implemented by engineering specialist solutions provider, Kentz Integrated Solutions, a division of Kentz (Pty) Ltd.

The STMS is responsible for the monitoring and control of various subsystems like the ventilation and fire-detection systems, where it can cope with various scenarios with regard to fires breaking out at various locations. The STMS is also responsible for energy monitoring and control, escalator/lift monitoring and control, as well as the management of the Heating Ventilation and Air Conditioning (HVAC), Fire Protection and Dewatering systems.

Each of the different subsystems has to be monitored 24/7/365 and alarms and conditions need to be filtered so that only certain information is passed on to the OCC (Operational Control Centre).

Each of the stations needs to be operated at a very high availability level and this in itself created an opportunity to design redundancy on the overall control room level down to station level, should there be any communication failures.

About Gautrain

Gautrain is an 80-kilometre mass rapid transit railway system in the Gauteng Province of South Africa, which links Johannesburg, Pretoria and OR Tambo International Airport. It is hoped that this railway will relieve the traffic congestion in the Johannesburg –Pretoria traffic corridor and offer commuters a viable alternative to road transport.

The train is expected to cut the number of cars on the N1 Ben Schoeman highway by 20%, with 100,000 daily passenger trips.

About Gautrain

The rail system was built by Bombela Consortium, a partnership between Bombardier Transportation, Bouygues Travaux Publics, Murray & Roberts, the Strategic Partners Group and RATP Développement, the J&J Group and Absa Bank. It is 50% owned by its international partners and 50% by Murray & Roberts and the Strategic Partners Group, the consortium’s black economic empowerment component.

About Gautrain

Initial works for the Gautrain started in May 2006 and construction went ahead after the signing of the Concession Agreement between the Gauteng Provincial Government and the Bombela Concession Company on 28 September 2006.

As of 8th June 2010, the OR Tambo International Airport, Rhodesfield, Marlboro and Sandton stations have been completed.

System overview

The ArchestrA servers are located at the Midrand depot with clients situated at each station connected by a fibre-optic network.

“Because of the distributed nature of Gautrain’s ‘shop floor’, reliable communications and redundancy are of primary importance,” says Sheldon Frade of Kentz. “Therefore the system has two modes of operation. In the OCC mode, everything is controlled from the Midrand Depot. If network communication is lost, the system switches over to the station mode and there is no longer any communication with the servers.”

The passenger density at all stations is likely to increase with time. Safety is therefore a primary concern with the early detection of malfunctions and prompt attendance to alarms mandatory. “We’ve made the HMI displays as readable as possible with services and their corresponding alarms overlaid on the station layouts,” says Frade. “For example, at the Sandton station, service status and alarm conditions are displayed on the backdrop of the side elevation of the station. As soon as an alarm is detected, the system automatically navigates to its location and displays the plan view of the appropriate level. In this way, fault location is very rapid and guesswork is eliminated. The navigation bar at the bottom of each screen allows operators instant access to the required status and alarm information of each service.”

The most compelling aspects of the project were the designing and implementation of the newly-created redundancy facilities and the flexibility of the ArchestrA technology to enable the design, engineering and installation of this project in a very demanding environment.”

Kents was required to use a generic template specified by the principal contractors for setting up the individual stations and integrating them all under one umbrella. “The generic template to which we had to conform was new to us and different from what we normally use with ArchestrA and the [AVEVA] range of products [from IS³],” says Carl van Wyk of Kentz. “We also had to design a system that would have more than 99.7% uptime.”

In addition, Kentz noted other benefits including the possibility of generating unrestricted custom navigation methods, the ability to add another (triple) level of redundancy if needed, the ability to use generic templates to speed up design time and the ease with which existing plants can be upgraded or expanded.



  • Engineered safety throughout the system – Rapid location and display of alarms allows personnel to respond rapidly to emergencies
  • Failsafe operation – The system is capable of triple redundancy if required
  • Maintained traffic density – The Gautrain operators have a Station and Tunnel Management System that meets and exceeds their performance criteria with respect to availability, thereby ensuring continued operation and minimising stoppages
