Prediction: $100 billion dollars will buy maybe 200 miles of track at most and then the whole projec
A single pair of tracks phoenix regional airport car rentals is like a one lane highway forced to accommodate two lanes of traffic moving in two directions. Trains can rarely operate at full speed, and only for limited distances. They have to stop and wait at sidings while other trains, moving in the opposite direction, pass them by. If a train stops to take on passengers, trains traveling behind it also have to slow down or stop.
This is the major reason why Amtrak trains between Los Angeles and San Diego require phoenix regional airport car rentals two hours and forty minutes to travel a route just over a hundred miles long. There simply phoenix regional airport car rentals isn't room on the tracks for them to go any faster.
Indeed, why haven't California's tracks been doubled? The answer is simple: Freight doesn't need double tracks. Freight trains are very, very long, and very, very slow, and they don't run very frequently.
The second reason why California's passenger trains are so slow derives from the very nature of single track rail: It's not safe. In fact, the use of single-tracked routes for passenger traffic is a time bomb.
This is what happened in Chatsworth, north of Los Angeles, on Sept. 12, 2008. A northbound Metrolink commuter train ran smack head-on into a southbound Union Pacific freight, killing 25 people and maiming 135 more, apparently because the engineer at the controls of the Metrolink train was sending text messages. (Picture of the crash is above.)
This collision forced the feds to order a further reduction in train speed. phoenix regional airport car rentals But it also led to the Rail Safety Improvement Act of 2008 , a joint industry and government initiative. The act requires railroads to create and implement "Positive Train Control" systems phoenix regional airport car rentals that would surround trains with a GPS envelope that would automatically shut them down if they approached another train.
But had the Ventura County Line in Chatsworth north of Los Angeles been double-tracked in Sept. 2008, the disaster is unlikely phoenix regional airport car rentals to have happened at all. The two trains, approaching from opposite directions, would have simply passed one another on neighboring tracks.
It is still possible to have accidents on double tracks a train might head-butt another standing still at a siding, for example but there would be fewer collisions, and they would happen at much lower speeds.
Nevertheless, even today, four years after the accident, the Chatsworth-to-Ventura phoenix regional airport car rentals line is still single-tracked, aside for one-mile-long sections north and south of the Chatsworth station. Apparently, there are hills in the way, and new tunnels would have to be dug alongside those built, perhaps, when Andrew Johnson was president.
The alleged $100 billion dollars phoenix regional airport car rentals for the high-speed rail fills the public trough with a lot of slop. Government hogs and their pot-belly porker friends will be feasting on that money for years to come.
Prediction: $100 billion dollars will buy maybe 200 miles of track at most and then the whole project will get cancelled once all the money is gone. By that time the new flavor of the month will be electric buses, solar powered big wheels and wind powered cars!!
a child? a moron? Yikes you guys get spun up, no? Are you spun up because you disagree with the environmental position re no double tracking phoenix regional airport car rentals on the beach? If so .those epithets phoenix regional airport car rentals seem kind of silly and childish .no?
