OpenTTD

OpenTTD is an open-source transport and logistics simulation inspired by Chris Sawyer's 1995 classic Transport Tycoon Deluxe, continuously developed by a global volunteer community since March 2004 with over 22 years of active releases.

Connect growing towns and multi-stage industry chains across procedural islands and continents from 1950 into the future. Lay intricate double-track railway mainlines with path and block signalling, construct multi-platform terminus and ro-ro stations, route road vehicle fleets, dig canal locks and shipping lanes, and upgrade regional airfields into intercontinental hub airports.

Key Features

• Four transport modes: rail (steam, diesel, electric, monorail, maglev), road (buses, trucks, trams), water (ships, ferries, canal locks, aqueducts), and air (planes, jets, helicopters).
• Path-based railway signalling (PBS), bridges, tunnels, terraforming, and shared vehicle orders with timetable automation.
• Dynamic town growth, passenger/mail demand, and interconnected supply chains.
• Bundled with OpenGFX 8.0 graphics, OpenSFX 1.0.3 sound effects, and OpenMSX 0.4.2 MIDI music.

Controls & Devices

• Desktop (Full) & Tablet (Playable) in landscape; Mouse required, Keyboard & Touch supported.
• Left-click: select tools, place track/stations, open windows. Right-click + drag (or Arrow keys): pan map. Scroll wheel: zoom. Space: dismiss news. F1: pause. Del: close windows.
