Please Add More Support for Diagonal Train Tracks

I like the 30. 45, and 60 degree diagonal tracks but working with is frustrating.
No 30 or 60 degree tracks can change elevation.
Diagonal tracks cannon be elevated side-by-side as the pillars interfere with the track next to them. this oversize collision boxes for pillars also affects trying to go under them with vehicles or other train tracks./
There are no crossings for diagonal tracks and next to impossible to build a pass under because to the above limitations.

Those limitations are there because of need to align all parts to grid. Some shapes are hard to fit those, so they are limited. That said i would love to see some pillars changes, like the ability to place them on more spots under curves, to have different shapes when diagonal to not take that much space and maybe even some bridge-like support (at additional cost) to allow better placement of multi-level rails at different angles.
