Here's a little tidbit about Tower 55 in the DFW area that is a huge bottleneck for rail transportation and will only get worse unless changes are made. This is a portion of the Texas transportation problem and is being looked at as port of the TTC concept.
Tower 55Some reports say that Tower 55 has as many as 120 trains a day on it's busiest days and on average is occupied 70% of the time.

The outlying freight rail corridor could help relieve congestion at Tower 55, a rail hub on the southeast edge of downtown Fort Worth where the north-south Burlington Northern Santa Fe and east-west Union Pacific tracks meet at grade to form one of the worst train choke points in the nation. ("At grade" means that the tracks intersect on the same level rather than one passing over the other.)
The congestion at Tower 55 is akin to the nightmarish auto and truck gridlock that would occur if there were a traffic stoplight at Interstates 35W and 30 in downtown Fort Worth, said Mike Sims, a COG senior program manager for transportation.
"Most rail people say [Tower 55] is the busiest rail intersection at grade west of the Mississippi," Sims said
I know there is talk about having all the containers from LB trucked or railed into a out of the way location.That would be the port of entry and containers would be inspected and unloaded there.
There is a massive bottleneck there and all over America. I would like the President to step up to the soapbox and tell us IF something is being done and what that something is.
