But unlike the airlines, that doesn't (currently) happen with Amtrak--for the same train, ALB-NYP will always be cheaper than BUF-NYP, so no one would ever book BUF-NYP when they only intend to travel ALB-NYP, and so there is no reason to have a rule that penalizes someone from changing BUF-NYP to ALB-NYP if their plans change--or, to use a more realistic example, to change SDY-NYP to ALB-NYP.
