thumb.jpg - The thumbnail image for this asset. A 240x180 jpeg.
driveto.texture.txt - The texture.txt file. See the section on Texture.txt files for more information.
driveto.tga - The texture file for the drivercommand icon.
shows image and alpha channel for 64x64 pixel TGA.
drivetocommand.gs - The trainz script file referenced in the config.txt.
