The series of US railway crossing challenges on MapRoulette is now
complete! Thanks to the many people who helped with this project! The
topology of the US rail-road intersection areas is now much more
accurate, since many of the crossings also required a geometric
alignment of roads and rails in the area. I'll write a diary entry
later with more details when I get time.
