Features

All the new trains will come equipped with condition monitoring systems to gather data from equipment on the trains. This enables continuous monitoring of the health of the equipment and allows the operator to carry out predictive maintenance for the trains. For the CCL trains, 2 out of 3 cars will come with an Automatic Track Inspection (ATI) System, which enables monitoring of the running rails, track equipment and sleepers while the trains are in operation. The ATI System supplements existing track inspection activities for timely and more effective identification of rail and trackside components which require maintenance.[4]
