Build 26028845

A major update to the most innovative and hated train game of 2025! Patch 18 brings new content, important bug fixes, optimizations and quality-of-life improvements.

New map

The new seventh map may look familiar to some people:

It's based on coarse real-world digital elevation map data, downscaled to dimensions of roughly 7x3 miles. This is the largest map in the game and may take over 50 hours of game time to complete. If you'd like to skip the other maps and jump straight into this one, see the Steam community guides for cheat codes.

Goodbye AI sky

The old Gen-AI skybox of Map 4 has been replaced with a similar one based on a real photo:

Map 2 also has a new sunset skybox:

All skyboxes are now double the resolution. All but two maps have a new fog effect to highlight the distances between faraway terrain features. (On maps 3 and 5 it would look bad against the skybox.)

Improvements to the behaviour of AI trains

The AI pathfinding algorithm has received numerous fixes to make it more reliable, reducing the number of "path not found" popups. You may still see those popups occasionally but they're usually short-lived and the train will start soon afterwards. If it doesn't, check that your track is intact and has no adverse wrong-way signs.

The driving and braking style of AI trains has been improved for more accurate braking. They no longer exceed the speed limit as often or get confused when the train is meant to reverse direction.

AI trains and the AI signaller no longer throw switches under player trains.

Existing AI trains in games saved with the old version may run worse than before until they respawn once or twice.

Gameplay and quality-of-life improvements

Height marker labels are now visible on the HUD. The label shows the height and, more importantly, the target grade required to reach that height from your current viewpoint. Previously this information was shown only when highlighting the marker on the minimap. The label is shown a quarter of a mile or 400m away which makes the markers easier to spot from afar.

Remember that you can remove all markers in one go from the bottom HUD menu, from the third menu row, if the view gets too cluttered.

The front and back signs on AI trains now show the speed limit of the train in addition to the current speed. This makes it easier to tell if a train is moving slowly because it doesn't have enough power or if it's because your speed limit signs are missing or wrong.

New laser spots along nearby tracks make parallel track laying easier. Previously you'd have to use the telephone poles as a guide.

Other QoL changes:

• Minimap now shows player trains in hard mode to make it easier to find your runaway trains
• Changed the automatic gearbox on the track laying unit to not shift up on an uphill grade if speed cannot be sustained in the higher gear
• Added camera transitions when entering cab and changing between interior and exterior views
• Reduced reflections on slow loco windows to make them easier to see through

Physics improvements

• Fixed track laying train getting stuck from the rear in the gate of an industrial plant
• Fixed brakes getting stuck in some cases even when the brake gauge shows they're fully released
• Fixed incorrect distance between cars after coupling two trains
• Fixed inaccuracies in some physics calculations that might have lead to trains suddenly derailing for no reason
• Added back and forth headbob in the cab view for trains of max 5 cars

Other fixes and optimizations

• Fixed a possible crash when placing a wrong way sign
• Fixed track layer sometimes turning 180 degrees and derailing when connecting to an existing track
• Fixed long stretches of ghost track sometimes appearing after removing track
• Fixed a bug causing one loco to remain inoperable after splitting a pair of locomotives
• Fixed train cars sometimes briefly appearing in the wrong place when they come into view
• Fixed signals and signs sometimes being held the wrong way around in hand
• Reduced lagging when using time acceleration in some cases
• Added operating system name and number of processors to error reports
