create graphics add to the Simutrans with Transport Tycoon.

[paulo.27]

Hello, recently I am creating addons for Simutrans, and observed the work of a graphic complement Chris Sawyer's Locomotion much like used in Simutrans.
Does anyone know where I can find 8 sprites (images with 8 different directions) of these trucks to try to make the graphics? and if this is possible ??
