Contrary to some statements;
Choke cables usually have a stainless steel cable inside the outer shell. Yes they do require lubrication, but if properly installed, and lubricated once a year (In our Ontario Canada location), work very well, but not in lengths of more than 6-8 feet.
Generally we use choke cables to prevent the need of bending over to throw a switch, or for a switch, too far from the operator, to easily reach.
Anyone contemplating full railway operations, as we practice around here, where the crew walk around with their train, can benefit from the use of inexpensive choke cables.
Choke cables are available in a variety of lengths, and can usually be found through, or at automotive retailers.
Devon, you will find that choke cables are rather INEXPENSIVE, and adaptable to so many situations. For some who enjoy mechanical challenges with bell cranks and other devices; choke cables are a great tool to “Play with”
I do not recommend bicycle cables, or any other plastic type cables for outdoor use.
