Metro completed city extension 2024 — Now runs Tallawong to Sydenham via Crows Nest, Victoria Cross, Barangaroo, Martin Place, Waterloo. Fully automated like Barcelona's L9, platform screen doors, 100% wheelchair accessible every station.

Payment: Opal card or tap any credit card directly. Every 4-6 minutes peak, 8-10 minutes off-peak. Air conditioned, quiet, reliable — Puts the old CityRail network to shame honestly.

Key tourist stops: Victoria Cross (North Sydney CBD/Luna Park), Barangaroo (harbour walks/Crown Casino), Martin Place (city center), Waterloo (inner south neighborhoods). Connects Epping/Chatswood for other train lines.

Real advantage over buses: No traffic delays, consistent timing, much cleaner than older trains. Catalans know good metro when we see it — This actually works properly unlike the tourist-packed Circle Line buses everyone recommends.
