A fleet of Sydney\u2019s Waratah trains have been fitted with intelligent software created by Downer EDI and Microsoft Azure teams to keep track of vehicle maintenance and other data-based decisions.\nThe NSW government ordered 24 Waratah Series 2 trains under its Sydney Growth Trains Project in 2016 - an additional 17 trains was added earlier this year and another 24 will be delivered this month. The trains are maintained by Downer EDI \u2013 which holds a 30-year contract with the state government to manage and maintain the existing fleet of 78 trains.\nRecently, Downer equipped the Waratah fleet of trains with over 300 sensors and about 90 cameras, backed by software that consumes sensor data from the fleet of trains. This allows predictive maintenance and data-driven decisions, said Mike Ayling, general manager of digital technology and innovation at Downer.\nAccording to Ayling, its engineers will be able to analyse trends across very granular data such as temperature of the train, outliers in voltages and currents and opening and closing times of doors. This means any small changes in the data can deliver Downer an early alert about what\u2019s going on and what might need attention.\nMachine learning and intelligent data analysis could also allow engineers schedule preventive maintenance before a failure takes place; and help in the need for replacement parts, to be ordered ahead of schedule, from overseas suppliers.\nDowner\u2019s rollingstock services business is one of the first adopters of the Azure based solution, used as the backend for their TrainDNA product.\nTim Young, executive general manager - Rollingstock Services, Transport and Infrastructure, Downer likened the solution to, \u201cdata analytics platform on steroids."\n\u201cWith such massive volumes of data it will allow us to establish trends in relative real time, allow us to predict failures in advance and calculate the remaining life of an asset more effectively,\u201d he said.\n\u201cThe advantage to our customers is that all of this takes place whilst the train is in service without interrupting the operation and at the same time enhances worker safety through the potential of removing high risk inspections.\u201d\n \nThe front end of the solution is an Angular Web App built on top of ASP.netcore services, with the solution hosted through Azure\u2019s Service Fabric ensuring scale and resilience.\nThe Azure IoT Hub feeds stream analytics into an Azure Data Lake Store and Azure SQL database and access is managed by Azure Active Directory with Power BI providing analytics and reporting.\nAccording to Ayling \u201cautomation and digitisation\u201d moves the company away from being an \u201cinspector and maintainer\u201d, to an asset maintainer.
