Mind the Gap
Many people are discouraged from using live frog points by the misconstrued idea that the wiring for the track is very complicated. Scrutinising commercial publications such as 'How to wire your layout' and 'Electrics for Model Railways' you would indeed be led assume that this is the case. Time to dispel that myth once and for all.

Unlike dead frog points where insulated rail gaps are not normally essential, live frog points and associated track do require a bit of forethought before finally pinning everything down. Much of the wiring illustrated in the commercial instruction books may be eliminated quite simply by the use of strategically-placed insulated single rail gaps, without losing any of the operational functionality.

The general rule is that if the track feed is towards of the toe of the live frog point, no gaps are required. However if the power feed is towards the heel end then gaps are essential to avoid the possibility of short circuits. Once these insulated gaps are installed, you can forget all about them. There is also no need for any additional wiring or switching.

Once again it is much easier to understand the principals of wiring using live frog points by looking at the diagrams. Remember that with live frog points the frog is permanently connected to its adjacent running rails at all times, therefore the polarity of these rails is dependent on the setting of the point, not on whether it is the furthest or nearest away rail. The diagrams will explain this much more simply than text ever can. Don't despair, keep it live.
