    That's fine. The system is reapplying power but then shutting down again because the short is still present. If the short is cleared then the system will come back up normally. Otherwise every momentary short would result in a complete shutdown requireing the power to be re-applied manually. Andrew Crosland

    DCC decoders use PWM drive. Almost all modern ones use a high (inaudible) frequency and it works fine with ordinary motors. It is *required* for coreless motors which can very easily be damaged by low frequenct PWM. Andrew Crosland

    Yes:-) A relco gives out a high frequency, high voltage limited to a very low current when the normal DC is interrupted by dirt. The idea is that the high voltage breaks down the dirt, or ionises the air, or something like that, and allows the DC to flow again. Andrew Crosland

    No, they are very different in all respects (voltage, current, frequency). The fact that DCC is AC has nothing to do with track cleanliness (or not). That's far more relevant. Decoder features can also help. Zimo decoders, with the capacitor backup supply, can be set to only stop on a section of track where there is good reception. A slow moving DC loco can stop on dirty track and then cannot be started without the hand of god. Andrew Crosland

    If they are what I think they are then start at this page http://www.rapidonline.com/Cables-Connectors/Connectors-Terminal-Blocks and look at the pluggable types. You need to know whether you want metric (e.g. 5mm) or imperial equivalent (e.g 5.08mm) pitch. Andrew Crosland
