- For
- Metro-history and transit-map enthusiasts
- Worth noticing
- The listings distinguish operating networks from never-built proposals, with dated histories and line and station counts for individual cities.
Field notes
The city index groups entries under country headings and exposes the archive’s coverage before a reader opens an individual system. Listings pair operating-network dates and counts with entries marked “Never built,” including proposed projects in Ukraine, Latvia, and the United Kingdom. The homepage describes date selection and playback, but the supplied extract does not show an individual map in use.
