I was never really happy with the level crossing on Die Keinnamebahn. The plastic roadway was designed to fit HO/00 gauge track and did not fit the Peco mainline narrow gauge track. The original crossing did not have infill in the tracks.
Today I replaced the plastic roadway with one made of wooden coffee stirrers. I used Games Workshops tints Earth Agraxx and Nuln Oil to stain the wood.
