issues trying to model a bundle of cables efficiently - advice sought please..

Hi all
I’m trying to figure out the best way to model a bunch of cables in such a way that allows me to control the curvature and position of the all the cables with a single bezier curve and also have a bezier curve associated with each individual cable so I can extrude along it to give me the body of the cable and use as a path to animate an object moving along the cable.

I need each cable (bezier curve) to be independent as I need the objects to be travelling at different intervals. Also being able to individually tweak curvature/positioning would be handy as well.

If anybody can give me some advice that would be great, I’ve been toying with it but I can’t figure out an efficient way to do it.

Thanks in advance.
Nigel.
