This seems a little complicated compared to other tagging schemes involving
intermodal crossings; seems like the two tags could be merged with some
supplemental tagging.  I do like this challenge concept, however, given
TIGER's somewhat lackluster modeling of railways, seems like a prerequisite
challenge would be to tiger-review it and get the tracks actually lining up
with reality first.
