In the native editor, railroads are gray only. You likely have the Highlighter userscript installed, which adds the dashes.

As long as you never junction the railroad segments to actual driveable segments, per the guidelines, then Waze should never route you along them. The only time it ever could, IMO, is if your GPS location reported by your device puts you near the railroad and Waze determines it needs to re-route you. I am unsure what would happen in that case, but it may try to route along the railroad. The problem there is that if the railroad truly never junctions with a real road, it wouldn't be able to route you very accurately, or at all.
