Description

Detailed description

“Multisystem locomotives are now used for cross-border services throughout Europe.

One problem of their interoperability is the integration of different country specific train protection systems with their respective warning tones. It means that the driver’s cab of a multisystem loco must be equipped with up to 9 different buzzers for cross-border service.
