CategoryGame Files
File Format Description

Resource file used by the Transport Tycoon (TT) and Transport Tycoon Deluxe (TTD) railroad business simulation games; contains a collection of sprites, which store the 2D graphics for game objects; used for displaying and animating railroad vehicles, scenery, and other game objects.

The original version of GRF files supported simple sprites. However, the new open source variants of Transport Tycoon, including OpenTTD and TTDPatch, support new graphics data in GRF files. OpenTTD's new format, called NewGRF, can include data for vehicles, cargo, buildings, railroad types, and industries.

OpenTTD provides GRF game packages, which are downloadable NewGRF files that can be applied to the game to display custom graphics and to alter game properties.
