brio splitter with auto-right and pass through

Let trains through from both exits, while trains entering it turn right.

EDIT: Working, tested prototype :-)

Anybody wanna try? :-)

Combined with a classic splitter (or one with the needle removed), it should allow a scenario with f.e. trains crossing.

Also check my special rails to allow new electric trains under old bridges :-) https://www.thingiverse.com/thing:1104257
