The main focus of this update is to improve the usability and aesthetics of the user interface. The layout and colours may still be changed in future updates.

The user interface is now scaled to remain roughly at the same size regardless of display resolution. You can change the size at any time (except in editors) by pressing the shortcut keys CTRL & Numpad+/-. If you prefer the unscaled interface of the earlier versions, you can enable it by ticking the "constant pixel size" checkbox from the settings.

The old keys for changing cabs ("change vehicle" and "change panel") have been replaced with simpler "move to next panel in front/rear" keys. The keys are insert and delete by default.

HUD helpers are now enabled and disabled from the HUD itself, rather than from the "Tutorials" button in the old version. Press Esc during the simulation to open the pause menu and click on the checkboxes to show or hide each helper (see image below).

Runs saved with the earlier version are incompatible with this one, so you may get an "error loading saved run" message when trying to continue your last run.

Detailed list of changes below:

User interface

• Restored old target speed calculation
• Added station stop waiting time helper
• Fixed camera drift in free train camera mode

• Fixed "continue last run" to restore camera in the right cab if it's not in the first or last cab in the train when saving
• Fixed key helper to not spam with keys that have no effect
• Fixed taking control of an AI train where the driver is not in the first or last vehicle of the formation
• Added "Saving scenery" text to top-right corner when scenery is being processed (frame rate might be erratic while scenery is processing)
• Fixed tooltips going vertically off screen

• Fixed brakes getting stuck on Class 37 when changing cabs before brake pressures have normalised
• Fixed AI to change panels correctly in some situations
• Fixed AI sometimes trying to accelerate in wrong gear or fiddle with the shifter while waiting for brakes to release

• Added separate checkbox to template properties in timetable editor to enable the downhill-aware AI target speed only for services where it's useful
• Added max speed to template properties in timetable editor, for limiting the speed even further from what the vehicles are restricted to
• Added node/section heading angle to route editor

The next update will be the second part of the user interface updates, adding support for translating the game to different languages.
