Change lines. When no single line reaches both ends of a trip, riders can now change lines once, at stops a grid square apart, if that beats driving. A "+" marks a stop where riders change. Close saves. Connect a destination with its ring nearly closed and the board marks the rescue: a fuller chord, and a label showing the seconds you had left. Your day in numbers. At the end of each day, the reward screen counts up the trips your network carried and the share that went by transit. City sounds. Every city now has its own sounds in the distance. Set the level with Ambience in Options.

New city: Amsterdam. The eighth city arrives, with its canal ring, a ferry that leads the network, and a big 2×3 arena. Smarter traffic. Cars now choose the quickest route instead of the shortest, so they steer around congestion. Routes are fixed when a car sets off, so cars already in a queue won't reroute. See a stop's reach before you place it. While you draw a line, a live preview shows each stop and the area it will serve. Smoother drawing. The build tip now follows the road's colour and day/night light. Dragging across tunnel staircases no longer shows stray corners. On elevated cities the stroke tip picks up the guideway colour. On Mac, right-click erase only affects tunnels while a tunnel tool is armed. Balance changes. Growth is gentler: slower rush-hour ramp, softer overtime, a gentler pin slope, slower London growth, and slower mega-buildings on water maps.

Improved visuals and refined maps.

Improved level crossings and road junctions.

Can now build diagonal and curved bridges. Performance improvements.

San Francisco — a seventh city. Includes cable cars, BART and ferries. It opens once you've unlocked the full game and scored 1,000 in every other city. Level crossings. Lay tram track across a road and the crossing gets barriers and flashing lights. Trams take priority, and cars get their turn in the gaps. Tram bridges. Lay track straight into water to throw a tram bridge across for one bridge permit. Draw a road over it later and the two share the deck. Route waypoints. Pin a bus or tram line through the streets you choose, right in the line editor. Track and tunnels have their own stock. Tram track can now run across open ground, not just along roads, and road tiles are scarcer, so each one counts. The tram and tube reward cards bring 12 track or 10 tunnel tiles. 4× speed, for the quiet stretches. Clearer buildings: every city's destinations are redrawn to read at a glance, even on iPhone.
