Local public transport with regional rail vehicles is part of the customer’s core business. Low maintenance costs and high train availability are crucial factors for the railway operator. Any downtime or delays can mean considerable costs and financial penalties.
The challenge
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.

Components monitored include gears in gearboxes, gearbox bearings, wheel axles and axlebox bearings.
