I'm new to O gauge building first layout using Fastrack. I previously modeled N and HO, so that's where my experience has been.
In the smaller scales it is always prudent to leave enough space between the track and edge of layout so equipment doesn't descend to the floor after a derailment (almost always in N, about 25% of the time in HO.
With the broader spacing between rails, and the third rail in the middle, I would think leaving the track after a moderate speed derailment is rare in O, but I don't have experience to know for sure.
Some layouts I've seen on Youtube leave a good deal of space between edge of layout and track, while other build to within an inch of the edge.
Does O gauge equipment tend to leave the track when it derails on Fastrack?
