Bridge with train tracks not connecting to elevated rail

Truss bridges can end with an elevation (as in not on the ground) but elevated rail to the same level doesn't connect to it. It doesn't make sense to allow bridges to end elevated if the rails can't connect to it because there is no road concept that can connect to it elevated so basically nothing can connect to it. It would be more useful to allow rails to connect to the elevated bridge than disallowing bridges to end elevated 🙂
Also if that is allowed it makes sense to allow bridges to start elevated too (max level 6 like the rails)

you can start and end bridges elevated by the regular keys, sometimes necessary to get an exact desired bridge path

you are correct, I just initially assumed they can't start elevated because the ghost disappears when using the elevation keys, I tried it now and it works

I think the issue with connecting regular rails to bridges is that the end pieces of bridges are special “portals”, and the rails on the bridge do not behave the same way that regular rails do, preventing the connection when there is no end piece on the bridge.

I am thinking the same about the ends but would still like them to connect to the regular bridge segments or at least have an elevated "portal" to connect to regular rails
