Model railroad, rerailer for Lionel O27 track

This is a rerailer for Lionel O27 Track. I didn't see any rerailers for O scale in train stores or websites so I thought it would be trivial to design one. It was anything but trivial. This design seems to work. It will handle a set of wheels off track, not a whole truck off track. I built it narrow so that it would fit between 2 sets of parallel tracks. Cars will make a sound as they pass over but that adds realism to the layout.
