your data-final-fixes line 15 and 45
table.insert(rail.collision_mask, "layer-14")
make your mod break space rails from space exploration, since it uses layer 14 as the space collision layer.
Consider excluding rails with the 'se-' prefix from that logic.

The problem is there is logic saying all rails must collide.
I will try layer-15 in the next update, but not sure if that will solve all the cases

Layer 15 is used for spaceship floors. Using that will probably break using rails in spaceships.. But that's preferable to not being able to use space rails in space at all.
