Public transit discussions here tend to be very metro-centric and also heavily focused on North America or often lost in the dead Transportation forum, so I thought it would be interesting to create another worldwide statistics thread.
The idea is to discuss and compare transit systems all over the world through ridership numbers, lenght rankings, and urban context. This can include: metros/subways, commuter rail, suburban rail, regional rail, trams/LRT, buses/BRT systems, everything.
I’ll start with the Wikipedia
list of busiest metro systems in the world:
---------- System -- Stations - Lenght - Annual Ridership (millions)
Code:
Shanghai ---- Metro ------- 415 --- 890.0 km --- 3,773.8 (2024)

However, “metro” can be a very arbitrary definition and often fails to capture the whole urban transit in most cities (e.g. Tokyo, Paris, São Paulo, etc.). Here a (non-exhaustive) table:
