Update v1.6 is live! This release adds the new Takanawa map, full coupling/uncoupling mechanics, and a new Diagram View.

🚉 New Map: Takanawa
・The biggest terminal map yet
・Three scenarios: Morning Rush (★5), DayTime (★3), Evening Rush (★4)
・Dense schedules using sidings, double crossovers, and multiple platforms

🔗 Coupling and Uncoupling
・Trains can now couple together, split apart, and park side-by-side in sidings
・Dedicated coupling signals and shunting departure levers added
・Stopped trains awaiting a scheduled uncouple now show a "Uncoupling Soon" state; departure signals are rejected until the automatic uncouple fires
・Coupling routes only open when the target train is on the approach track, preventing accidental blocking of other movements

📊 Diagram View
・Open and close with the F1 key or the on-screen "Diagram" button
・Drag the header to move; resize from the bottom-right corner
・Horizontal scroll and mouse-wheel zoom on the time axis; the minimap shows current time at a glance
・Inter-station travel times are calculated physically from per-section speed limits, acceleration, and braking patterns
・Stringlines cover coupling, uncoupling, and turnaround moves. Hover any line for a train info tooltip

🎨 UX Improvements
・Tooltips with keyboard shortcuts on the time controls (pause / 1x / 2x / 4x), map button, and diagram button

Thank you for playing! We are continuing development toward v1.7 (Approach locking and settings screen, targeting mid-June).
