Basically, each route is for the various games, with each boss or character encountered being a station. Take the dark red/crimson line, which represents EoSD's bosses; you have Rumia to start with, then Daiyousei as the firs stage mid- and end-boss. Some of these are out of order to make them fit in nicely, but this is an awesome representation of the touhou characters.
It's a chart that connects the post PC-98 characters to the games they appear in. I believe that the idea behind deleting it is that, even though it's a cool graph, there's nothing else to it. Everything else under the diagram or map tags is, at least, accompanied with at least a character or background, with the exception of post #298972 which was uploaded by albert years ago.
The review would probably be on whether or not simple infographs would be considered under something that danbooru accepts.
Now for the fun part: If you start off from Rumia, follow the games in order and go on each track at least once, what order of characters could you use?
You can only use the main stops to change game lines once, but you can pass over them if you're on the same line (eg you could use Yukari to go from IaMP to IN, but then you wouldn't be able to go from SWR to SA)

Start from ESoD line at Rumia and take it to Sakuya. Get on PCB line at Sakuya, take it to Alice. Get on IaMP line at Alice, take it to Yuyuko. Get on the IN line at Yuyuko, take it to Mys-chin-chin Get on the PoFV line at Mystia, take it to Aya Get on the MoF line at Aya and (you have to) take it to Reimu Get on the SWR line at Reimu and take it to Yukari. Get on the SA line at Yukari, take it to Sanae. Get on the UFO line at Sanae, take it to Marisa.
(Here's where you have to get tricky)
Get on the Hisouten line at Marisa and take it to China Get on the ESoD line at China and take it to Dai. Get on the Fairy Wars line at Dai and take it to Cirno. Get on the PCB line at Cirno and take it to Youmu. Get on the TD line at Youmu and take it to Mamizou (end of the line).
Boom. Rumia, Sakuya, Alice, Yuyuko, Mystia, Aya, Reimu, Yukari, Sanae, Marisa, Meiling, Daiyousei, Cirno, Youmu, anyone from TD (I picked Mamizou because end of the line)
Adding STB and DS would of made this easier, because then Nue, Flandre, Eirin, Kaguya and Mokou become switchback points to a lot of other characters instead of (effective) dead ends.

I suppose that's true, it's just that my home country doesn't have trains (even being the 5th biggest in the world in total area), so looking to a train map in Germany, for example, is quite amusing and unnatural to me.
