E-signal

The E-signal (Swedish: Ägovägssignal, lit. "owner's road signal") is a type of grade crossing signal used in Sweden on very low-traffic roads crossing a railroad track, when the same landowner owns the property on both sides of the railway track and only a few residential buildings can be reached from the road. An e-signal operates in the opposite fashion of a conventional grade crossing signal: it is lit when no train is approaching the crossing, and when a train approaches, it extinguishes approximately 30-60 seconds before the train's arrival. This is intended to provide a 'fail safe' function, in the event the signal bulb has blown or the power has failed; e-signal mountings are always supplemented with an information plate indicating the function of the signal. Due to its method of function, the e-signal is considered to be potentially confusing to drivers, and is being phased out of service; however, in Sweden there are still approximately 170 e-signals in operation.[1][2]
