Added Advanced Mode, which can be enabled from Options in Settings. In Advanced Mode, you can create layouts such as double-track railways. Main changes: - Added support for double-track layouts. - Added curved rails with different radii. - Made it easier to place rails side by side. - When placing island-style stations, nearby parallel rails can now also be recognized as station rails. - Removed placement restrictions between ground stations and elevated stations. - Unified the behavior of station buildings and platforms. - Station buildings and platforms are now treated as one continuous stopping area, improving train stop positions. - Improved rotation and post-placement controls for station buildings and platform parts. - Added new island-style station buildings and platforms. - Improved camera behavior in driving mode. - Fixed an issue where trains could tilt outward instead of inward on curves. - Adjusted rail and girder collision detection to improve placement and stability. - Other bug fixes and improvements.
