There is only one underground train station, please create more...

... and this one is made of the vanilla metro station preset.

Could we have some underground train stations that look like Berlin and Hamburg S-Bahn?

Perhaps a combination, with crossing lines, one metro (U-Bahn) and one train (S-Bahn), both underground and a proper S/U sign at the entrance?

There's a couple of sunken stations, plus Helsingborg Central, which allows for two parallel lines.

I really mean underground stations.

And just a normal entry/exit, not a huge building.
I want to place them like metro stations, the footprint could be like 4x2 or 6x2 for crossing line stations, but not that massive.
