I second to you.
Even the simplest station requires a long reading for everyone who is new to the game, and I believe some people cannot understand the idea of automated blocks, Sz signals, etc, that is unique to rail dispatcher systems. It took me an hour.
Now I know what to read on the table, but I still don't know when and what to communicate with the next station.
I guess some tutorial stages (easy, intermediate, and hard stations, with single-player situation) are coming with step-by-step instructions, but until that happens, 'demo' mode is what I ask.
