Route Performance

We know that on-time performance is an important ingredient in fulfilling
Amtrak's quest for providing quality customer service. As many of you know,
the tracks Amtrak trains travel outside of the Northeast Corridor are owned
by various host freight and commuter railroads. We offer this information as
an opportunity for you to follow along as we work with those railroads on the
path to improvement and to assist you in planning your trip.
