A one evening turntable bash

[P5se Camelback]

Gray matter functioning :!:

Whereas ...
A. This is not a scale model out on the layout proper, to be senicked and detailed, but an "off layout" method of turning locomotives ...
B. The simpler, inexpensive, more straight-forward the solution, the better ...
C. It appears that alignment of the turntable bridge is intended to be by hand ...

Might I suggest a solution that mimics the old, tried and true "knife switch." Such a solution could be developed to both convey power to the rails as well as align the rails properly for entry onto and exiting off of the turntable. Polarity could be handled by a toggle switch between the power source and the "knife switch."

It's not elegant ... but it should solve the problem simply and inexpensively, as well as provide a positive method of aligning the turntable tracks at the same time.
