Hi,
I do not know where they came up with that 5% figure for nickel silver alloys!
That is way too low judging from my experience over the last 15 years with
code 332 nickel silver rail. My track is 280 feet per round trip and there is
only one electrical connection. Lighted passenger cars look just as bright at
the far end as they do where the electrical connection is located. Running
sparkies has never been any problem, there is no detectable slow down at the
far end. I do clean my track each spring after the pine pollen season. It is
a pleasant looking brown color with a hint of gray to it. If you consider
the internal conductivity AND the fact that N/S patina is also conductive,
compared to brass or aluminum, the N/S is by far superior. Yes, it is
expensive, but the best always costs a little more....at least that is what
the madam always says..........
Keep your steam up!
