V/Line WOLO sensors

Over the past few months V/Line have started to install new sensors along the Regional Fast Rail lines. Stress gauges have been inserted into the rail itself, and weather stations have been erected in caged compounds along with short stubs of track connected to sensors. It is believed they form a monitoring system that will let V/Line see what is happen to track in hot weather, and only put WOLO speed restrictions into place when they are required, not whenever the temperature is forecast over a given temperature. The Geelong line has both the stress gauges and weather stations, the Ballarat line has at least the weather stations.
