Flickr user Karwick presents a wonderfully detailed Steel Buffer-Stop for use at the end of rail line spurs.
Details like this, in my opinion, are what model railroading is all about. I love to see powerful locomotives, detailed rolling stock, and well-constructed buildings, but details are really what make layouts come alive for me.
The parts usasage on this build give it a nice thin look, though it still feels massive enough to stop a run-away wagon. Karwik also presents some heavier alternative buffers in his gallery, which also contains some nice detailed town elements as well.
