>>10461625Atlas 21st Century track is pretty good. It's also expensive, but there's a full selection of of curves and switches from O27 out to O99. It looks pretty realistic aside from the Third rail. It is made of nickel silver, so post war magna traction won't work on it, but you won't have to worry about rust.
It.is apparently durable enough to withstand weather and sun and is used by garden railroaders who use O gauge.
