I think it would be better to rename Rapid Transit to S-Bahn Mitteldeutschland. I guess the route was called Rapid Transit as it was the first Rapid Transit route in TSW 2, but now we have more than one Rapid Transit route, using its official name like all the other routes would be more informative of what the route offers.
I believe it was named as such (like how London-Reading is named GWE and SPG is also called CSX Heavy Haul) because I believe (but happy to be proven wrong) that there were going to be 3 versions of the game based in the US, UK and DE (or EU), with the subtitles "CSX Heavy Haul", "Great Western Express" and "Rapid Transit" respectively. obviously this never came to life. I could be completely wrong though.
