I have recreated Milan's main train station in minecraft up to scale and with the use of the create mod made modern trains that work and placed them inside. This is a massive station which is very impressive and looks even better with shaders!
I have made a video about the entire project which you can find here: https://youtu.be/pSEiX5_O5bA

The map has a grand square which has a tram stop and a metro station below (both working). The building has a front entrance with large columns (note the glass windows in the ceiling thorough the station) followed by ticket offices that lead to the modern part of the station and to some stairs which lead up to platform level in a second hall. There's also two side entrances and the metro station connected to the underpass. Then there's the gates that lead to the magnificent archway consisting of 5 arches of different heights and of course the platforms where the trains are. At the other end of the archway the tracks regroup and go forward into some tracks that go into the wilderness.

You can download the map with the required mods and play around with the trains or if you have a slower computer and still want to visit the station you can download THIS map which is for vanilla and therefore doesn't have working trains.

The version of the map is JAVA 1.19.2
Required mods for forge:

Required mods for fabric:

That's it, I hope you'll like this map!
