tesla secondaries/locomotive wire

	It has several.  Depends on the coil, but:

	Just so.  However this touches on a theoretical point that has been
	rattling thru my mind:
		What if one so manages the secondary (tertiary, if used?)
		design so that the distributed L/Distributed C AND THE
		helical resonator mode are the same??

	Are there inefficiencies assocaited with having two resonant freqs?
	It seems there might, but i am speculating...

	My (sideline) understanding is that 'helical resonator' approach
	gets closer than 'distributed l/c approach'.  Are there advantages
	to aiming for both to coincide?  (or is this routine and i missed it?)

Locomotive wire:
	Well, as a railfan, of the technical style, i never heard the term.
	The cable described appear suitable for wiring to tracion motors,
		flexible, high current, maybe a litte light in insulation
		for mechanical purposes.

	A single lok may run 6,000 hp continuous, with 1000-1200V on the
	traction motors. (say 1000 hp/750 KW each), meaning 100-200A
