Overhead Line Equipment in Real-Time

OLErt (Overhead Line Equipment in Real-Time) integrates visual measurement algorithms (from Oxford University academics) with Incremental’s analytics platforms and precise positional certainty data, to prevent OLE incidents such as pan flips, contact force and out of tolerance stagger.

By continually monitoring and evaluating train infrastructure in real-time (in this case, the Overhead Line Equipment), the system can alert users to issues as they occur and flag potential issues to enable timely preventative action.
