>>1899936>>1899830I feel if they actually want to built something like U0, the line needs to be built to completely different standards to actually work as intended.
The Ringbahn is about 37km long and needs about an hour to complete one circle, while the S-Bahn has a top speed of 80 km/h and the U-Bahn of 70.
How is this supposed to work with a >60km ring line?
