An electronic control box designed for practical training in NSW Rail Vehicle Detection (one aspect of railway safeworking) which interfaces real-sized signals. A 24m section of track-circuited 2-foot gauge track is also part of the equipment. 2 rail vehicles are used as the train/s. The track is divided into 5 block sections and activates the signals accordingly. The "signaller" can switch in different combinations of signals to simulate real-life situations.
