One of the guys on a German NA Railroad forum asked me for suggestions. The space was given, the theme was given and the scale was given. The result - not quite finished - looks like this
Some of the scenery will still need to be finished in AnyRail, the rest in Corel PhotoPaint. Oh yes, the track level at the lakeside is assumed as “0”, up at Mine #2 the level is +240mm. the max. grade is 4.4%. Tightest radius is 400mm (in a portion of the big loop) other than that it’s 460mm (18").
