I don't think the FRA cares about a battery-powered <2' mining railroad, that probably isn't even under its jurisdiction. I would extend some ties (or install extended ties between the factory ones) and build a walkway off the extension on at least one side.
I question the use of N scale track in S scale because the ties are too small and too close together. (No problem with N gauge, I call it Sn20 and built a tram in it myself. I also have Sn2, using HOn3 track gauge, which is why I call it Sn20.) If you don't want to hand lay the track, I would use HOn30 flextrack with the ties spread further apart, which would look better IMHO. Micro Engineering lists HOn30 (HOn2-1/2) flextrack with Code 70 rail. On a previous layout I used HOn3 flextrack for Sn2 already and spread the ties further apart. On my current layout I'm hand laying the track so tie size and spacing is up to me. If you want to hand lay track, Kappler has ties 5" X 5" X 5'(KP00Sn2) and 5" X 5" X 4' (KP00Sn18).

Since I plan on using Kato 9mm track on many of the Sn2 (only) sections of track, I stopped by the hobby shop to look at their selection of Kato track. Among other things, I found that the S9 locomotive, which is cables, will not fit on an `N' scale bridge which has vertical sides, due to its width. However, Kato makes a 9mm deck truss bridge which does not have vertical sides, but is actually slightly narrower then the critter locomotive itself. Other then it's width, this bridge is well detailed and would look great crossing a stream or small gully. Under FRA rules, would a railroad be permitted to operate a cables locomotive on a bridge that's narrower then the locomotive itself? Were the operator to fall out of his seat, there's nothing between him and the ground under the bridge. Jeff Allen ------------------------------------ Yahoo!
