Since there are something in the neighborhood of 60 share-a-ride vans that come in from the Valley, it wouldn't seem to be too difficult to re-position a number of them at the railroad depot in Anchorage to help facilitate cross-town traffic.  Palmer already has a station at the fairgrounds, and Wasilla has already been looking to move the train stop there to the corner of Palmer-Wasilla Hwy and the Parks; so instead of meeting the van at the park and ride lot, Valley commuters could go to the train.  It would cut the number of miles the vans travel, and gas, oil, maintenance, and replacement costs.  It would also be a good way to avoid the long delays for winter ditch divers and other accidents, and should be a lot less expensive than adding additional lanes of pavement to accommodate increased passenger car traffic.  Good coffee and wi-fi on a self-propelled car could be pretty popular.  Let's look at transportation as a whole, not one mode at a time.
