hi all, Got a quick question. On the n-scale (code 80) layout I built I used mainly 9 in radius turns on it. I noticed with this one kato loco I have, a SD90 (6 wheel trucks), it throws any stock cars attached to it off the track because of the tight turns (oops.) My atlas (4 wheel) have no problems. So, I'm already starting to brainstorm a new layout before this one is even done for the future, and curious what's the recommended turn radius for large locos like this? I know bigger is always better, but what would oyu say is the minimum you could use and still make a turn safely (mainyl for space reasons). I love the Kato line and would like to use many more 6wheeled locos next time. Thanks.
