Overhead Lines

The analysis of catenary wires is important for the rail sector to measure changes over time. As catenary wires sag, or wear, this can cause major defects along the electrified route. Rail Vision provides contactless approaches to catenary wire measurement of wire height, stagger, thickness, and change in position from track centreline. Our systems use high speed camera technology to measure wire height, stagger and width. The data can be thresholded to detect exceptions that need intervention and further correlated with track geometry to understand the cause of underlying abnormalities.
