Yo, I was wondering if anybody could help me with mein problem. How would you set-up a DPST switch to terminate the power in just one section, with the rest of the layout still working. Also I want the power to come back-on. [:-,]

No elaborate switch is needed to kill the power to a siding/ section. A single pole single throw(simple on/off) to interupt power to one rail is all you need.
To be more complete. Instead of running 2 wires from your power pack to the rail, run one wire from the power pack to a rail and one wire from the power pack to one terminal on the switch. Mount the switch any place you want. Then run a wire from the other terminal on the switch to the other rail. There needs to be a gap in the switched rail between where the wire is attached and where you want the block to end.
This can be done with a DPST switch, but you only have to use 1/2 of the terminals. OR you can switch both rails by using both sides of the switch. That is not needed, but will work.
