Having reached the stage of wishing to indicate TOT to prevent any more senior moment accidents I decided to make up one of the Roger Amos offerings. On testing and thinking about it ( as opposed to just making it), it became obvious that these little devices will function with or without controller power being present and simply require to be attached to each rail to provide the circuit through the on-track motor. It does help that when one of our computers died I was able to re-use the Power Unit to provide wedges of 12 & 5 volt DC.
Have any of the fraternity used these Twin Tee units in such a manner? If so, have any drawbacks been revealed ?
