One wonders whether there is a point where Amtrak might consider expanded MN operations thru the Hellgate to NYP a competition issue. I doubt that a New Rochelle local would bother them at all (aside from logistics/scheduling hassles), but what about a limited stop train between New Haven and NYP?
Would Amtrak even like to have some of their customers from NH, Bridgeport, Stamford etc siphoned off to free up more thru slots, or would they resent MN cherry picking some of their customers with better prices, even if that meant experiencing more station stops.
As commuter lines from various places reach out and meet each other in the middle, an opportunity for a lower class of service between major cities is approaching feasibility, if not yet convenience or desirability. How low can they go?
