At one point on the branch line to the garage, the track had to cross the walkway to the backyard. This was also the only wheelbarrow route to the backyard so the track needed protection from being run over. A ramp type grade crossing was formed from RapidSet patching cement and it has held up very well. I would guess that it would hold up to 1:1 scale vehicle traffic as well.
The cement should be formed so that it is not quite as high as the railheads. This allows track sliders and cleaning pads to rest on the track and not on the cement. Also, the flangeways must be cleared all the way down to the tie strips. There should be no rail joiners inside the cemented section. The track is also held down to the brickwork below with TapCon masonry screws.
