DSB Train Service

DSB train service has now taken over the brake pad inspection system and a three months trial period has commenced. The Site Acceptance Test was done on the 18th of February 2011 only a few days after the original project plan from summer 2010. An excellent cooperation with DSB staffs made it possible to deliver on time.

The system inspects the brake pads when the train enters the DSB maintenance facilities at Kastrup. The inspection is done by six cameras mounted between the rails looking up through protective glass at the brake assemblies. All brake pads are measured to an accuracy of 0.1 mm and the dimensions are entered into a database. The wear on each individual brake pad is monitored. No wear means non functioning brakes and excessive wear indicates hanging brakes.

A caution is flagged when the brake pad is due for replacement. Data is transferred to the DSB maintenance computer and work documents are issued. When the train leaves the workshop, the brake pads are inspected again to check that the maintenance has been done.

During commissioning we had winter conditions where the trains carried snow and ice. This tested the system under the worst operational conditions.

Two systems are now in operation taking care of brake inspection on both IC3 and IC4 trains.
