Rail Monitoring

Tracking locomotives in transit helps rail companies to optimize performance, detect problems and reroute equipment based on local conditions. This results in:

  • higher customer satisfaction
  • shorter transit time
  • better scheduling and
  • safe, more efficient operations

Yet despite investments in the latest equipment, even the most modern tracking systems perform poorly and inconsistently due to the challenges of collecting and monitoring data from fast-moving assets operating through remote terrain.


RTI provides the connectivity software and services to help monitor train performance before, during and after trips. RTI Connext enables intelligent information exchange from onboard and remote applications, resulting in less unscheduled downtime, energy savings and higher utilization rates. Its standards-based data distribution infrastructure can connect thousands of onboard mobile and remote assets, transmitting data from dispersed sources, and aggregating it for real-time analysis and response.

RTI Connext is highly scalable and provides hardware and software interoperability through a common databus. Authorized users and applications can access any data from any location. With its publish-subscribe architecture, back-office client applications can simply subscribe to the necessary data. Train operators can receive configuration updates in real time, without waiting for scheduled maintenance.
