Meeting the challenges faced by rail operators

Moving passengers quickly, efficiently and safely while reducing complexity and costs is a daily challenge for rail operators. Achieving this requires the right com- munications platform. DAMM provides a reliable and complete trunked commu- nications solution, enabling private and secure voice and data communications across all activities in rail and metro operations.

Efficient resource allocation and communication enable prompt decision making, in turn contributing to efficient and confident management of operations.
