Ok I'll bite.  How does the railroad control the crossing gates?  Here in
Illinois, Chicago and NorthWestern changed over the technology at the
crossings about 2 years ago and have had major problems ever since.  Gates
come down and stay down without a coming locomotive.  Once I watch the gates
come down when the train (albeit moving about 3mpg) was about 25 feet from the
intersection.  

I've also noticed that commuter trains will cause the about 5 gates to come
down ahead, but a freighter will only bring down 3 ahead.  Anybody will
any knowledge they would like to share???
