Interesting Information - HO Code 83 vs. Code 100 Track

Nickel-silver vs. Brass Track

Nickel-silver oxide conducts electricity where as brass oxide does not, so the nickel-silver rail is preferable because it does not need to be cleaned as often.  Dust remains a problem with either type of rail.  The Nickel-silver rail is about the same hardness as brass and it's just a as easy to solder.  The choice of scrapping the older brass track depends upon your railroad's finances.  Many modelers recycle the brass track into industrial spurs and car storage tracks where the locomotives do not run.  Once it's painted, weathered, and ballasted the older brass track looks just fine.
