Just by looking at the switches, it seems that they have "live" frogs - am I correct? If so, does that mean that the two central "V" rails have to be joined to other tracks via an insulated gap to prevent short circuits? Thanks.

As you have gathered, this means you need to use some form of isolation to overcome this. Marklin make insulating fishplates for this.

As you have gathered, this means you need to use some form of isolation to overcome this. Marklin make insulating fishplates for this. I have to admit I never heard this before. A search with Google led to this picture: Source: http://www.schwellenhopser.de/Technik.htm I see a plastic frog with two separate contact lids - no need to use insulation IMHO. I'll have to take a look at my Z gauge turnouts. You need insulation when you want to have two ovals, connected by turnouts, but with the ability to run two trains independently. No insulation needed with only one electric circuit (or second circuit from catenary).
