- First, the nit. If it's "private right of way" there are no crossings
- so what is the problem?
-
- Second, to address the issue. Light rail (like the SF or SJ trolleys)
- (a) is already planning to stop at the crossing to pick up passengers,
- (b) is travelling much slower, and (c) weighs MUCH less than heavy
- rail. A car travelling at 60 takes one heck of a lot longer to stop
- than one travelling at 30. A heavy car takes longer to stop at 30
- than a light one. Combine them.

- Where you have a crossing, you have a safety problem. How many
- deaths are acceptable? For how much money? Comparing crossings
- with auto intersections is a bit of a red herring (at least, until
- you have as many trains through the intersection as you have cars.)

- Um. There are other people in the county. And, just as I am
- subsidizing the auto junkies, they are subsidizing the train
- junkies.
