Glad to hear this project is still on the rails. Was worried that it was being unmaintained.
That said, I hope to see a bit more cities from the Middle-East (eg Dubai, Mecca, Tel Aviv) and Asia (Delhi, Bangkok, Taipei, Kuala Lumpur).
Maybe a bit of world specials too (Beijing, busiest system; Chongqing, longest monorail system; Jakarta, longest BRT system)?
