Hello all.

My apologies if this is the incorrect place to ask. If that is the case, please do direct me to a more appropriate one.

I have a question to anyone who might know about elevated metropolitan railways.

In Melbourne, Australia, we have an elevated railway that cross the middle and outer suburbs to avoid level crossings. It carries all metropolitan commuter traffic, regional commuter traffic (V-Line) and freight (picture for reference).

After seeing the Wuppertaler Schwebebahn (picture for reference) I am interested in the concept of having multiple lines supported by the same elevated infrastructure. Has this been done anywhere?

For example, imagine you have something like the Scwebebahn suspended under the elevated platform to serve as local commuter traffic, use the rail over the top as regional and limited express to major transport hubs for changing lines, and add a third tier above the existing line for regional and freight.

So really, what I'm thinking here is to have a multistorey elevated rail.

Has this concept been done anywhere? If so, what are the terms for looking into it some more? I am not much of a rail nerd. Just autistic, but my fixation is in other fields.
