Would like to build an HO layout with two main lines ... how far apart would the tracks have to be to be realistic?
It would be a good idea to address tunnel and bridge clearances as well. When I started, I was running 2-6-0's and 40' boxcars. Now I run Challengers, and "Plate F+" cars like double stacks and auto racks. I've had to modify 2 bridges and 3 tunnels because I built for the small stuff. While it may be a case of art imitating life, I'd rather not have had to rip everything apart and redo it.And that is generally measured between centerlines in each case. Whatever you do, think of possible/likely future needs. You may be operating a short engine and 40' boxcars now, but the heavy majority of us 'upgrade' before long when we develop a strong hankering for a larger locomotive and longer cars. So, as much as it may seem unlikely, or that it goes against your credo at the moment, you may want to give yourself as much room as possible to account for contingencies.
