how do you set up siding for one engine so you can use another

[Donon]

I have a Bachmann 2 wire N scale set up and would like to add a siding to park one loco while using another.

Hi Donon,

You can either block (gap) the siding using an insulated rail joiner and an on/off switch, or use a power routing turnout to the siding.

Look here, scroll down to basic wiring there is a simple picture;

Good luck
