"The product of the railways is the successful arrival of passengers at their chosen destination." Clearly, this was not written in the USA. With a few exceptions (NE corridor, Wolverine route), Amtrak is forced to share rails with host freight (goods) railroads who could give a hoot about the expedient delivery of passengers. The Big 4 (BNSF, UP, CSX, NS) would rather just let their freight have priority and pay a minimal fine. Sadly, this will continue to be the case where Amtrak does not have their own right of way (NE Corridor, Wolverine).
The US is very much the exception, not the rule.
