Yep, lots cleaner and more efficient. I've been seeing this
posted a lot lately, must be some new Cato Institute talking point. Consider
500-1,000+ people on an Electric Multiple Unit train versus 500-1,000+
cars on the road. Even with that train powered by a coal plant that
is still going to be orders of magnitude more efficient than the
passengers being in cars. And further more a railway can carry many
more people than a freeway: >The carrying
capacity of a freeway lane is roughly 1800 vehicles per hour, or 2000
people per hour given average vehicle occupancy of 1.11 passengers. A
typical six-lane freeway therefore carries up to 12,000 people per hour
in both directions. >A double-track
suburban railway, meanwhile, can easily support one train movement every
three minutes in each direction without straining its capacity. A
six-car train can carry around 1000 passengers before reaching crush
conditions. Thus the rail line can carry at least 40,000 people per hour
in both directions, and perhaps more depending on the signalling system
and vehicle design. And before anyone says HURR 4 PEOPLE IN
CAR ask yourself how often you see that as the norm? |
