While I'm all for new routes, this whole thread was about Vancouver, WA - Maricopa, AZ. It's interesting that in this amongst all threads, no one seems to want to restore passenger service to Phoenix, AZ( where I'm sure the OP was actually headed). It's only the 5th largest city in the country. The Rodney Dangerfield of cities.
Yes, it's the fifth largest city in the country if you're going to split hairs and count the number of people who happen to share a common mayor. But if you look at the
primary census areas, it's only the 13th largest. When you can easily walk from Cambridge, MA to BON, it strikes me that there's some value to using a metric that acknowleges that there being a political border between nearby municipalities doesn't necessarily prevent people from getting from one municipality to another easily.
Restoring rail passenger service to Phoenix would require getting it to have a passenger station again. It would also require one of the following:
1) Restoring the tracks to the west of Phoenix that were previously used pretty much exclusively for passenger trains. Maintaining several tens of miles of tracks for six trains a week isn't terribly cost effective.
2) Building new high speed track that would get a lot more people out of airplanes and onto trains (possibly going so far as to make Phoenix to Los Angeles flights obsolete), justifying more frequent service and thus helping to cover maintenance costs; and while I think this is a good long term plan, it requires a very large capital investment.
3) Having all of the Sunset Limited passengers who aren't going to Phoenix experience the added travel time of taking the existing spur into Phoenix from the east, and then backtracking (is that going to lead to even more connection that don't work on one end of the route or the other?)
4) Running a shuttle train between downtown Phoenix and the point where the Phoenix spur meets the mainline, in which case you also need a platform where the meet happens, and possibly extra sidings so that freight doesn't get blocked on the mainline while passengers transfer. However, the equipment for the shuttle train could probably be something like a P42, an Amfleet coach, and a cabbage, which Amtrak could probably come up with with little difficulty.
Or maybe there's yet another option I've missed.
