Does IR have axle counters, hotspot detectors, trailing equipment detectors, etc.?
[5/99] Axle counters are widely used by IR to ensure that all wagons or coaches of a train have indeed passed a given point — out of a block section, out of the station limits, out of yard limits, other point zones, etc. (‘last vehicle proving’, ‘block proving’, or ‘block verification’, serving the same purpose as the visual ‘Last Vehicle Check’ or LVC that is done otherwise). Axle counters are often used along with track circuits to control automatic block signals (i.e., to detect the presence of a train in a section. Axle counters may be of the single or multiple entry type. Axle counters today are mostly of the electronic variety. They use piezoelectric sensors on the tracks, which are triggered by the weight of a pair of wheels moving over them. Older models with mechanical sensors have also been used. Usually two sensors are installed, at either end of the track section to be monitored, although more complex installations with more sensors are sometimes used. The counts of axles r
