Is telephone wire old type single core copper any good for wiring layout. Just been given some by friend of mine who works for open reach.

No its very poor, being so thin and single strand.

Thats a shame I got loads, thanks for answer Brian

I use it all the time for internal lighting for buildings using low power LEDs. It is easy to hide and bend round corners. Also useful in constructing PCB electronic circuits where high voltage and currents are not an issue. As Brian says it can be brittle so not recommended anywhere where movement can occur.

Got to agree about the fragility of telephone cable. If you do want a multi core cable that is fairly robust and yet a small diameter is to use alarm cable. This is flexible due to using stranded wire cores and is available in 4, 6 and I think 8 core versions should cope easily with most low current circuits such as lighting but I would not recommend it for solenoid point motors.

I have to wire up peco insulated double slip and it is bit more complecated than I thought. Have looked at utube and not much luck there. How are double slip wired for DC control.

How many DC controllers will the Insulated frog DS need to accommodate?
If one for all directions then nothing needs doing, other than possibly adding rail feeds to the outer stock rails.

1 double track controller. slip left to sidings, strait over, up line, across right to down line. Hope that is not as clear as mud.

For two DC controllers fit IRJs to all exit tracks and feed the two outer curved stock rails from a DPDT toggle switch. The switches middle tags feeding the DS rails and each pair of end tabs connecting to the appropriate DC controller. Then when setting a route through the DS flip the switch to set that move.

The other alternative for switching if the approach points are powered is to use a Peco PL15 DPDT micro switch fitted to the point motor and allow that to switch the DS rails

Thank you very much Brian.
