or make train track movable on bearing

If this were to be added, I think scheduled trains would need to be able to control the turntable so that their routing works.

better one for you, allow tracks to be supper glued, then you can use a mechanical bearing, and sequenced gearshift to make a turntable

One suggestion I would have in regards to this:

Add a special type of track that is movable. I get that due to how train tracks are implemented as a network that works even outside of chunks, and how trains are built with sometimes glue intersecting train tracks, making normal tracks movable does not make much sense. However a special type of track that is movable and separate from normal track (e.g. movable track would not be able to have train stations disassemble/assemble trains on it.) could work as a compromise.
