As I went home today, I noticed for me a typical thing that isn't in this mod. It is the Route overview.

It is similar to route signs or route overviews on platform doors, but it is for both directions. It shows the route as a vertical line with stations marked. The end stations on the sign should face to the platforms from which trains to that station go (in the real life example below, trains on track 2 on your right go to Nemocnice Motol station and trains on track 1 on your left go to Depo Hostivař station).

It makes you navigate the station better.

This is real life example:

You can take a screenshot of the map (from a platform screen door, or just draw it yourself) and put it as map art or use mods like SignPicture, Image2Map or Images on a normal block

I think you can use Route Sign
like this：

The problem is that the route sign shows only one direction. The point of this horizontal route sign is that in station concourse this sign tells people: "Those all stations on this line, you are here and go right if you want to go to stations on the right, and go left if you want to go to stations on the left." Is meant to guide people thru the station.
