Real-time overhead line monitoring for safer, smarter maintenance

OLErt is Incremental’s intelligent monitoring solution for Overhead Line Equipment (OLE) and catenary systems. It continuously detects faults, wear, and anomalies—helping teams avoid costly incidents and optimise maintenance planning.

A single de-wirement can cost up to £2 million. OLErt helps you prevent them.

What OLErt Solves

Undetected faults: Identifies pan flips, arcing, vegetation, and stagger issues before failure occurs
Expensive, infrequent inspections: Uses everyday passenger trains to deliver continuous monitoring—even at speeds over 100mph
Fragmented maintenance planning: Provides virtual track walks and actionable insights through continuous video and data capture
