    The Pembroke & Cheltenham High Desert Railroad: Planning
    @Mitch.   FYI,  The thermal expansion of aluminum rail is huge compared to the Stainless,  you will have to engineer for the expansion and contraction with your wide temperature swings.

    THAT is the DEFINITION of oxidation, not corrosion.
     
    My reference sources are dictionaries and scientific texts, besides my scientific training. You can call it corrosion till the cows come home.

    Joe, 
    I don't anneal brass. Since it holds its shape after you bend it, I just use those flat pliers. No problem.
    Years ago, I worked in a sheet metal shop, where we used hydraulic brakes on all kind of material: aluminum, brass, tin...  more

    No Steve, corrosion and oxidation are not exactly the same.
    In aluminum, the process of anodizing is done by oxidation.
    So anodized aluminum is corroded?...  more

    Big changes at Staver Locomotive for Spring Steamup
    My guess is TIG welding for aluminum rails. Looks like no track power (judging from the metal connecting the points), is it all steam power or do you allow battery too?
    Can you explain more of the general philosophy, is it a club, do people join? Are ther...  more

    Correct as common (residential) chain link is 2" aperture.  2.5mm is 8 mesh. https://www.amazon.com/Aluminum-Unpolished-Finish-E2016-06-Diameter/dp/B005H2UX5I

    There is another 1:32 solution, Piko has 1:32 rolling stock, the boxcar, hopper, etc are 1:32.
    Your aluminum rail won't corrode, the right term is oxidize, and aluminum oxide on the surface of your rail will give you some of the best traction possible.

    My late friend Dirk was building a #14 when life got in the way, took me a bit to find but here are some pics... code 250 aluminum, milled brass frog.
    The guard rails are as he found on the UP's mainline tracks behind his home.
