[John Swindler]

And the day may not be too far off when the cars could (not would) be 
equipped with GPS tracking, and then let a satellite and computers control 
safety on single track.

There's good line of sight on stretch past County Home siding, but there is 
a somewhat blind "S" curve between Yanovich and Fair grounds.  And the 
Nachod signals are not totally reliable.
