>>1065344The Hannover light rail has been through a lot. Plans were changed and money kept running out all the time. Pic related are stub tunnels at Waterloo station, the very first underground station in the city.
The D subsystem was by far the biggest loser. The original plans from the sixties were to put them into a ring-shaped tunnel under the Central Station and build a large extension in the southern half. Currently, D-west has the slowest service, the lowest ratio of raised platforms, the shortest route length and is the only line to end at an overground station in the city center. One branch of D-south was instead connected to the C subsystem and the extension was never built.
There's currently lots of construction work going on for D-west. Stops are moved, raised platforms are being built and there's a new terminus at the central bus terminal, only a few hundred feet from the abandoned station I posted.
