Good evening, on the announced route from Stuttgart to Heilbronn, it would be nice if the underground S-Bahn line could be extended to Schwabstraße station. This would implement the entire S5 line from Schwabstraße to Bietigheim. Stuttgart Central Station underground should be included in the game, then only the stations: Stadtmitte, Feuersee, and Schwabstraße would be missing. There's a turnaround curve at Schwabstraße, which is so unknown to me in Germany and would make the game very interesting. Best regards MCHAMMER
Expanding the line to Schwabstraße would indeed give the S5 some nice closure and the turnaround there could make for interesting timetable options Main extra effort would be the creation of the 3 additional underground stations 19MCHAMMER86 mentioned. I'd support this idea
