Frankfurt’s U1 is red, U2 is green.

@LunaDragofelis @RuthODay similar to #Düsseldorf and #Köln, tho both are fucked up to some degree:

• Köln has two different entry heights in their system which are incompatible and thus can't use every set on every line.

• Düsseldorf has some stops smack-dab in the middle of roads with no platforms, making them unfixably inaccessible due to foldout-stairs at steep angles, as even if the city was willing to setup platforms, it would not be possible due to lack of space, blocking emergency vehicle access and anything but pedestrians.

@LunaDragofelis @RuthODay no, because at that section, the tracks are embedded in the road surface and the road can barely fit one lane per direction and narrow sidewalks between the buildings, with no parking spaces along the entire road.

• raising the sides would not work as then the building entries would be below that new street level.

• lowering the road isn't possible without having to relocate all the utilites, incl. sewage.

• Either way it would split a road into two parts that are too narrow to be navigateable by a firetruck or ambulance and thus the City Firemaster would be forced to veto that in accordiance with State Fire Codes.

• Putting the line underground wold be the next best option, but would cost billions as that part of town is literally just a Sandbank on the Rhine River, making tunneling extremely hard, expensive, dangerous and problematic.

So yeah, there is no win unless they were to to the.correct thing and standardize their fleet to low-floor carts with automatic ramps at doors and rebuild basically every single station in the network (cuz that would be cheaper than tunneling!)...

• That's the sad part abour real-life city planning: If you gonna yeet stuff, this isn't instant nor will it be an option in many cases.
