isolating the power so that work around Kings X may be tricky.

Just lift the rails for a short section south of the station.

But I agree that you'd have to see where the power feed was, and make
sure that was sufficient within the proposed schemes.
In the central section, a current section might only be a few hundred
yards long and is easily isolated by touching the telephone wires
together and laying down short circuiting bars in the section.
