11245Re: [carfree_cities] "Biden rolls out $1.3 billion for Amtrak"
- Mar 13, 2009You need dedicated track for 100+mph operation. And to maintain the
kind of service that was normal in the old days--"You can set your
watch by the express"--you need separate tracks for passenger and
freight service, except for some local passenger service possibly.
With the slower speed of freight service these days (in the days of
steam there were a couple of 100mph passenger expresses) the
railroad cos. can allow trackage to deteriorate somewhat without
commercial penalty.If a container shows up a few hours late it's not
a big deal. If 800 passengers show up a few hours late you have 800
complaints. (The Coast Starlight is routinely two hours late into
LA. In fact, Gina and I were so shocked that we arrived in San Jose
on time that we broke out in hysterical laughter.)
Passenger routes should be double tracked whenever possible, and
freight should run on separate tracks. A freight train can pull onto
a siding and wait for another freight to pass. A box of dog food
headed to a warehouse doesn't have the same temporal necessity as,
say, the bride's parents en route to the wedding.
