Frankfurt U-Bahn cab ride (Line U6 - Ostbahnhof to Heerstraße) ~ Train Simulator

A full-length run on the Frankfurt U-Bahn's Line U6, with our motive power being the trusty Flexity Swift U5 yet again. We'll be calling at the following stations on this 8.5 kilometre-long route:
Ostbahnhof
Zoo
Konstablerwache
Hauptwache
Alte Oper
Westend
Bockenheimer Warte
Leipziger Straße
Kirchplatz
Industriehof
Fischstein
Hausener Weg
Stephan-Heise-Straße
Friedhof Westhausen
Heerstraße
I don't understand why those last two intermediate stations are both still open, especially when they're only 220 metres apart.
As I was driving the U5 train, I found that there was no need to ever go all the way to full power. This unit accelerates so quickly that you don't really need to put the throttle past 60%.
