ABSTRACT:
An apparatus that indicates the speed of oncoming trains at train crossings comprises a large digital display attached to a drop gate or alternately on a side gate crossing sign for those crossings without a gate. The digital display is surrounded by a large sign indicating the speed of an oncoming train. A speed detection device aimed in either direction on the track to determine train speed. An interface converts the detected speed into a digital display. It is envisioned that motorists knowing the speed of an oncoming train will be less likely to try to beat the train through the crossing.
