>>1366311It's still a Stadtbahn. This is just showing the limitations of the Stadtbahn concept.
Pic related is the network of Bielefeld Stadtbahn. Blue are tunnels, red are surface routes. The sections I marked in orange are the ones that lead to such a low average travel speed.
What is causing the problems? The marked sections are the only ones where the Stadtbahn doesn't have a dedicated ROW, instead it runs on the street in lanes that are also used by automobile and bike traffic. Or where they just put a stop at every traffic light at every intersection, sometimes only 200 meters apart. Traffic light circuits should have been planned around the schedule of the tram, not the other way around.
On all other sections of the network, the Stadtbahn is moving at reasonable speeds without interference from cars and traffic lights. Especially in the tunnel sections or even on the brief cross-country strech north-west of the northern orange marking on line 2, where it reaches its top speeds of 70 to 80 km/h.
I'm also LMAOing at the mentions of Duisburg and Cologne in the video. Duisburg's stadtbahn network is a fucking joke with an eight-minute tunnel section without any stops right in the middle. That is sure to increase average travel times by a whole lot.
And Cologne has so much grade-seperated light rail that it really should be converted to an actual metro at this point.
