Real timetables for public transport in Cities: Skylines II — fixed departures, auto-sized fleets, and terminus timing points. Works for buses, trams, metros, trains, ferries and aircraft.

Turn any line into a scheduled service:

• Set a first departure time and peak / off-peak / night intervals.
• The mod derives how many vehicles the line needs and raises the game's vehicle-count ceiling so the fleet isn't clamped.
• Vehicles are held at each stop until that stop's scheduled departure, then leave — proper timetabled service instead of bunching.
• Surplus vehicles retire at the terminus after finishing their loop, never mid-route.

No timetable set = the line runs exactly like vanilla. Includes an in-game departures board.

• Pure ECS — no Harmony patches. It writes PublicTransport.m_DepartureFrame to hold vehicles to their scheduled minute, drives the game's own vehicle-count policy for fleet sizing, and manages retirement via the vehicle's own route flags.
• No network access at all — nothing leaves your machine.
• Filesystem: writes only its own settings file and a log (TransitTimetables.Mod.log). Nothing else.
• UI: ships an in-game panel (React module, .mjs). It's UI only — it reads/writes the mod's own settings, no external calls.
• Dependencies: none beyond the base game.
