v1.5.0

2026-07-28

v1.4.17

2026-07-20

New Feature

San Diego and Detroit get cross-border demand. Riders come in from Tijuana and Windsor, the border corridors glow on the demand map, and there's a front-page story the first time you see it.

New Feature

The tutorial teaches demand now. Who's travelling, and where they're going.

New Feature

Hover a city on the globe for a map preview, population, and size.

New Feature

Interface size slider in Settings. Scale the whole game up to 160% if it reads small on your display.

New Feature

The measure tool is on by default. Click along the map for distance and walking time.

New Feature

Controller section in Settings with a switch to turn controller input off entirely. Use it if your flight stick or wheel is fighting you for the camera.

New Feature

Monitor picker in Settings if you run more than one screen. Pick one and the game moves there.

New Feature

The version number in Settings opens the release notes, and there's a What's new button next to it.

Improvement

The globe stops spinning once you grab it.

Improvement

Crossovers don't need Advanced Mode anymore. You need them to turn trains around at a terminus, so hiding them was silly.

Improvement

Route errors say what's actually wrong. Which stations, and whether a stop needs both platforms or manual ordering.

Improvement

Finishing the tutorial drops you at city select, with one exit confirmation instead of two.

Improvement

Tutorial steps tell you why, not just which button to press.

Improvement

Station clicks while editing a route are much faster on big networks.

Bug Fix

Load in the pause menu works when the save is from a different city. It was doing nothing at all.

Bug Fix

Blueprints don't get refused with a licensing error anymore. That one could strand you halfway through the tutorial.

Bug Fix

No more stale pending save loading when you start a game without resuming.

Bug Fix

Bug Fix

Bug Fix

Hyperloop, Loop Line, and the junction achievement actually unlock now.

Bug Fix

Newspapers describe the day instead of the moment they print. Papers come out at midnight, when your trains are parked and nobody is riding, so a busy network kept getting written up as abandoned.

Bug Fix

Ridership figures in the paper are right. Passengers per day, per train, and per station were all reading far too low on a long save.

Bug Fix

Newspaper stories about crowded stations can actually run. They checked numbers that are always zero at midnight, so none of them ever printed.
