I actually had the privilege of taking in 2 Fremo events while I was over in Germany. The first one we went to was a smaller affair in a very pretty town called Petersburg.
There we met up with a few fellows engaging in Fremo operations, and again some really stunning modules with very nice scenery.
Walburg is actually copied from a prototype with little or no compression and features a functioning hump yard.
If I hadn't seen it, I wouldn't have believed it.
