Might be a silly ask, but would it be possible to get smaller train tracks? I would love to use this more but the tracks feel so big, and are still subject to the wide turning radius of the tracks, I think it'd be nice if we could get a smaller version with a tighter turning radius :-)

I second this ask. Would be very cool to have a tiered train network.

I second this ask!

Sadly not possible without game engine changes. It used to sort-of be possible: https://mods.factorio.com/mod/TinyTrains but even that method I don’t think works any more.

See https://factorio.com/blog/post/fff-377 - all those shapes and radii are hardcoded in the engine.
