Walt, I don't believe they are designed to be separated in the usual sense, they are used as a unit. All the load in those sections is going to the same facility were the containers are remove for another form of transportation usually truck or container ship.Posting these photos to illustrate my train question. Some of you more familiar than I am will know the answer. I saw a train that only had a single set of tandem wheels between the cars for three or four connected cars and then the normal sets of wheels between two cars,, each on the end of the car. How do they separate the two cars with only one set of wheels as in the first picture, or do they? I hope this makes sense when you see the photos.

Three or four cars connected as in the picture above and then another set of three or four are joined as the picture below.
