A condition monitoring test rig which monitors vibration and temperature of bearings and gears in gearboxes and axles has cut maintenance costs on trains, and costs significantly less than installing complex onboard monitoring systems. Local public transport with regional rail vehicles is part of a railway operator's core business in Asia. Low maintenance costs and high train availability are crucial factors for the operator. Any downtime or delays can mean considerable costs and financial penalties. To ensure the best possible availability, the gearboxes and wheels of all the wheelsets of a train, including its axle and gearbox bearings, are regularly inspected, overhauled or replaced. The customer was therefore looking for a solution that would ensure the reliability and accuracy of checks, while also minimising the downtimes of the trains.
