The new LMS Bracket / Junction signals are coming to the end of their development stage with decorated samples currently being evaluated. The mechanism incorporates servo motors in a separately contained control unit that simply snaps onto the base of an installed signal. The clever design eliminates the need for wires between the base unit and the signal superstructure.
The OO & O Gauge Servo actuated signals come with almost everything you need to set them up in the box, all you need to really do is hook up an appropriate power supply. For the modeller who really doesn't like soldering there is a 2m plug and play extension cable available to help reach between the signal and your control centre.
