I'm not sure if you already have the track (and want to see what it could make) or not, but have you considered using AnyRail (
AnyRail™ - The easiest model railroad design software) to plan your own layout? Once downloaded, you can select the LGB track library and build a track plan using the LGB track section numbers (or with the mouseover text, the description) . . .

The
free version allows you to create track plans with up to 50 track pieces (nothing to stop you creating and saving multiple 50-piece layouts). You can pay (£47) to have a version with unlimited track pieces.
Just a thought
Best wishes
