No glass rails, but I did have a half-height staircase to use with a separate landing/level. You can remove the railings and ballusters on each side individually by editing the different element textures/colours. See SF 3d-models 382.

stairs_mini.sh3d (.sh3d file with cutout).
stairs_mini.zip (just model .obj - will not cut accurately as the railing extends beyond the top of the stairs).
