Brazing Nickel Silver

I'd like to join nickel silver parts together--by whatever means makes the
most sense. The joint should be conductive and strong--this would be for
joining model railroad rails made of approx 18% nickel alloy. What's a good
technique?

Silver-brazing is the time-honored method for making strong, nearly invisible joints in nickel silver (which contains no silver, BTW).

What's wrong with just soldering them together? That's what most of us model railroaders do.
There are exceptions for special cases.

I'd like to know how he's going to keep the plastic ties from melting, unless he's handlaying track and soldering it together before spiking it down.

When putting several pieces of the yard long rail together, it is better not to actually solder or braze the lengths together but rather just provide electrical connections between the rails with loops of wire. The reason for this is that the layout expands and contracts a lot over the years and having a solid piece of rail many yards long will make for difficulties with kinking and so forth of the track. Better to allow the rails to move about a bit and that will allow the track to stay where it belongs. If you're laying your own rail, butt soldering with silver (5% or so silver) solder will do fairly well in place although working a piece of metal under the rail for additional support will help.
