My setup is located under my house in the garage area. Sadly that area is shared with the clothes dryer so the air is very moist. This makes the m-tracks rails rust quickly and also the springs on the turnout mechanisms. To that end I have started procuring c-track with its stainless steel rails to replace the rust-prone track.
This has slowed down my endeavours but I am over half way there now. I am looking forward to the nice quality of the c-track as I have had some real issues with keeping good connections with the old track.
Hopefully by Easter I will have enough pieces so I can lay it all then!
