I have a 4 x 12 HO layout in my basement. So far I have the track down but no scenery and it is not totally wired. Here is my track plan. I have a single loop, no distortions, just a loop of HO that runs across the whole thing. Along about 5 ft or so of one side of the loop I have double track made via a passing siding along the straight. Off of the passing siding I have a single siding. This is all I have. I have a HUGE area in the middle that I am going to have to fill with SOMETHING. I am sort of thinking of having some of it be a narrow gauge railroad. I have some N scale track. I am wondering a few things. Please answer my questions anybody. 1. Does regular N scale track work well for HO narrow gauge, and if so, does both HOn3 and HOn30 run on N scale or does only HOn30? 2. Is it easy to convert an N scale loco to narrow gauge HO? What sort of tools would you reccomend? 3. What are some good companies that make narrow gauge freight cars and passenger cars? 4. Is there any good out-of-the-box plastic narrow gauge available or is it all brass and stuff? Add any other info you know about it.
