Due to space restrictions on suitable areas in my house to run trains, my layout went from the original 10x10 L shaped layout I had originally planned down to a 4x6 table. 4x6 just isn't enough to get serious with O gauge trains so I've been thinking of putting nostaglia back in it's box for now and converting to N gauge. Since I don't have any experience with these little guys, where should I start? What are the good starter sets to look at? (I prefer steam but I may incoperate some diesel as well.) What are my cost differences using flex-track as compared to sectional track pieces? Whats the good and bad of each? How hard is it to bend flex track and get it "right?" I don't want to bend it too far only to find out I've kinked it or made my curves too sharp. What do I use to be sure my curves are right? Is it just an eyeball thing or is there some sort of way to measure them? I don't know if I want to go DCC just yet. What are the advantages of traditional running VS DCC? Are there N gauge sets out there that provide sound without DCC? Thanks for any info.
