This is a data project for efficient changing between lines in Berlin. Take a look at the generated-branch for a auto-generated Markdown-view on the data in this repository.
Previously, data has been manually collected in a hand-crafted Markdown files. Although these files are considered deprecated, they are still here.
The data is stored in the data.xml file. Its format is specified here. The current file format is not capable of storing all relevant data. This is why we're drafting a new file type, see stations.xml.
