With temperatures expected in the triple digits today in Portland, the Goldilocks light rail lines will be running at less than 35 mph (assuming that they run at all). That shouldn't be an issue, since nobody works on Saturdays, so the power lines that Tri-Met has that conveniently sag when it gets warm really shouldn't be a problem for anybody. Heck, it's not as though light rail has much of anything to do with transit, anyway:
"Light rail "is not worth the cost if you're just looking at transit" says top Metro growth planner John Fregonese. "It's a way to develop your community to higher densities."
They came right out and admitted it, 20 years ago. They don't care if their silly little two-car "trains" are delayed by warm weather or cold weather or whatever; the whole idea is to spend billions of dollars on rail systems so that they can spend millions of dollars to entice developers to build apartment and condo bunkers in so-called "public-private partnership" arrangements.
