why do you not make your own background? It is easy with my "do-it-yourself-background/backdrop" (when you have some experience with digital pictures and trainz-folders on your hard disk) - click down "my content" for the download! The included "ReadMe"-file explains how to do it.
Be aware that SPLINES dissappear within a short viewing distance. I experimented with background-splines and dropped the idea: even on a single board they jump in and out depending from the distance - not usable for backgrounds.
