Metro Trains Melbourne’s Comeng, Siemens and X’Trapolis fleets have undergone major maintenance to ensure the trains are kept to the highest standard and improve the experience for passengers.
Melbourne trains are being retrofitted with wireless data recorders to monitor key train systems, improve safety and reliability, and maintenance, enabling the trains are available to run on the network more often.
The On-Board Diagnostic (OBD) system will give Metro engineers access to near real time data so they can monitor train performance, identify faults sooner, and maintain trains more efficiently.
Metro has recently installed the state-of-the-art technology on 174 three-carriage X’Trapolis train units.
The OBD project is being completed at the Newport rail workshops and has now moved on to the Siemens fleet.
The system is used to monitor everything including vibration in critical train bogie components, heating, ventilation and air-conditioning systems, as well as passenger body-side doors, traction, auxiliary power supply, and passenger information systems.
This helps Metro diagnose and respond to potential issues sooner, reducing the risk of passengers being delayed by train faults.
Metro’s general manager of rolling stock, Dave Carlton said that Metro was completing a world first with this technology.
“We’re proud to be leading the largest-ever retrofit of remote condition monitoring equipment on an existing train fleet, globally,” he said.
“The data we collect from this technology is being shared across Metro, which benefits our operations, infrastructure and network development teams.”
Technical upgrades have also been carried out on the oldest vehicles in the Metro fleet. 75 per cent of the Comeng fleet, which in total numbers 179 trains are being overhauled, with passenger-facing and engineering improvements.
In 2017, a three-stage, $75 million upgrade project began, funded by the Victorian government.
Metro’s CEO Raymond O’Flaherty said the project will extend the life of the fleet.
“The Comeng fleet has served the people of Melbourne for almost 40 years, they are brilliant trains and they’ve certainly got more life left in them,” he said.
“We have very stringent maintenance programs for all our trains, that’s one of the reasons they are still so reliable. It’s also essential that we utilise all the technical advances that are available, and this life extension program makes sure that our passengers have the best possible experience on board.”
The life extension project has three stages, of which the first two are complete.
Stage one included critical-safety improvements to Comeng train doors – a feature now standard on all Metro trains.
Stage two was focused on the passenger experience, including rearranging and reupholstering seating, installing LED lights, new grab poles and straps, safer gang-way bellows, and new digital signage on the front of trains to give passengers destination information.
Upgrades have also been made to the driver’s instrument panel.
Stage three is the project’s final stage and is now almost complete. It involves upgrades to the passenger information system, with digital displays inside the carriages tracking the train’s journey in real-time.
Victorian Minister for Public Transport Ben Carroll said that upgrades would also increase safety for passengers, with new high definition CCTV cameras been fitted with a wider field of view that can be accessed remotely, which will support Metro and Victoria Police investigations.
“We can access camera footage remotely as soon as issues are reported – helping Metro and Victoria Police respond to incidents as quickly as possible and giving Victorians peace of mind that their journeys are safe.”
There are also improvements to hearing-aid links for people with additional needs and upgraded speakers for clearer on-board announcements.
On the engineering side, the trains’ air brakes are being overhauled, while the electrical relay panel and traction systems are being upgraded to support a safer journey.
For the Siemens fleet, Metro’s middle child, Metro partnered with accessibility group Vision Australia to support new safety upgrades for the Siemens fleet
New bellows were needed between carriages, which has instituted an “outer wall” that fills in the gap between the train and the platform.
By providing an exterior that is flat along the full length of the train, Metro has reduced the risk of falls for vision-impaired passengers who may mistake the gap for a door.
Since an upgrade program commenced in February this year, more than 20 per cent of Siemens trains have been upgraded with the new bellows.
As well as being safer for passengers, the upgrades also provide sound-proofing, making the carriages quieter for a more comfortable journey.
Together with Vision Australia, Metro used a mock-up train carriage to test the design to ensure it provided all the necessary safety features.
The mock-up train is used by Vision Australia to help familiarise vision-impaired passengers and enable them to move confidently around trains, while also teaching guide dogs how to navigate the network.
Carlton said this work was important for the community.
“The work we do to make sure our trains and stations are fully accessible for all our passengers is absolutely essential. Providing a public transport service means making sure that every person can use our network without limitation,” he said.
“These new gangways give us extra confidence that not only are we continuously improving safety, but we are improving the passenger experience. It’s not just about getting to your destination, it’s about getting to your destination as easily and comfortably as possible.”
