OUTCOME

  • Faster communication across clinical and operational teams
  • Discreet alerting during sensitive situations
  • Integrated radio and paging communication
  • Auditable delivery and response tracking

OUTCOME

  • Discreet reporting for passengers and rail staff
  • Faster response to incidents across the rail network
  • Integration with police control room systems
  • Two-way communication with passengers when needed
