Last Friday, I visited the Innotrans, which is one of the world's largest railroad trade fairs held every second year in Berlin, Germany. On the stand of yard operator RLC, which is a subsidiary of the HVLE Railroad, there was a small, pizza style H0 model railroad layout:

Part of it was a small limestone plant decorated as Fels Werke, which is a mining company running several limestone mines in the Harz Mountains. The logo was obviously taken from the Fels Werke homepage. However, I'm a little suspicious, this idea might be stolen from a diorama, I built several years ago:

Of course, I will not complain since adopting nice ideas from other modelers is also one of my favorite practices.
