Seriously, thank you. The only use I had for the railroad before was Graal City to Snowtown, though it really wasn't even faster than the pathway anyway.
Concerning this image, would it be possible to add some sort of support/bridge/structure graphic over the gap to give it a bit more realism? I'm no graphic artist, otherwise I would volunteer a sample.

It does sound realistic, but it would block the pathway to get to swamp.
