I know that Amtrak would like to be the most efficient train system possible. The only thing that could make it more efficient would be to eliminate the passengers! They are such a bother. I believe the train from DC to New Orleans would always arrive exactly on time if we didn't have to stop for all those pesky passengers. They are always wanting to put baggage on the train.
You know, there are trains in Canada that will stop at a river crossing and drop you off, unloading your CANOE from the baggage car. We can't even deal with a bicycle.
