Hi All

I am new to all this and am struggling a little with point wiring. I will be going DCC and have electrofrog points but am not sure how/where to use insulating fishplates. I want to have four points all together what do I have to remember? Any help would be much appreciated.

Hi and welcome.

I'd recommend keeping Brian Lambert's excellent site to hand. This page should give you the basics on point wiring - http://www.brian-lam...ted frog points

I had problems on my first layout with certain locos (and especially 4 car EMUs) shorting out on pairs of points and diamond crossings. On layout 2 currently under construction I have used Brian Lambert's suggestion to put insulating fish plates on the frog ends of points and so far this seems to have completely eliminated the problem. Does require some extra track droppers probably.

This site is good for DCC wiring - http://www.wiringfor...om/switches.htm

On my own 00 layout I have done just the same and put insulating fish plates on the frog end and it works OK

what do I have to remember?


The following is all you have to remember for all wiring DC and DCC in EVERY track orientation if you follow the following rules it will always work:
1. fit insulating fish plated to every frog rail (that;s the two middle ones out of the four) Run a wire (there may be one already - depending on the point) to the centre common of a spdt switch (usually mounted on your point switching mechanism)
2. run a wire from each of the stock rails to each of the corresponding power bus
3. run a wire from any dead section following a point (typically in a siding) to the corresponding power bus.
4. supply power to the poles of the spdt switch in [2] so that the frog gets the appropriate power when the point is switched.
The only* difference between DCC and DC is that in DC the wires to sidings may have switches for section breaks.

* except for complicated (eg multiple controller layouts)

Thanks for all the help. My problem now is that when Point A (in red) is thrown I get a short an my controller reboots, is it because I have not connected any of the frog wires from the points? All points are Peco electrofrog.

Oops, how do I attach a jpg?

No, shorts do not come from omitting something but from connecting something that should not be connected. If you have 6 insulating joiners round that point as it appears on the plan then there must be a fault within the point itself, scrutinise it.

Thanks for the help. I no longer have my problem. Schoolboy error I'm afraid, I did not have isolating fishplates in all the correct places. I can now now carry on laying more track and await my next problem!
