Nexala - A Trimble Company Nexala CAB Advisory System

Nexala CAS Cab Advisory System

The Trimble® CAS cab advisory system is an on-board solution that informs drivers about train performance and adherence to timetable.

By facilitating improved driver behavior and timetable conformance the Trimble CAS system minimizes delay penalties and improves overall service to customers.

Linked to real-time diagnostic information to alert drivers of potential faults, this tablet-based solution also allows the driver to report issues with the train directly to the control room and maintenance depot.
