There are some groups trying to revive the Chicago,
North Shore, and
Milwaukee r.o.w. as an alternative to a 3rd airport in Chicago. The idea is
to build a high speed rail link from downtown Chicago to Mitchell Field in
Milwaukee.
CSX (Chessie, PennRR, NYCentral, etc) abandoned significant local
right-of-way, which provided a local opportunity that couldn't
be passed up. Now we have a local RR company who uses the red
keystone as its logo (the line was originally PennRR). They're
doing pretty well, too...
