Single intermodal container car

Postby BobLI » Sun Dec 16, 2018 3:19 pm

Is there a new type of intermodal car that only carries one container? I’ve seen them mixed in with double stack wellcars and just curious if it’s a new development.

wellcars can either have a single or two containers, it's just a normal wellcar with less load

There were two-axle flatcars with reporting marks TTOX. I googled TTOX, and ended up on the Trainsmag website, which has the following:
The cars were built beginning in the 1980's to accommodate 48' trailers, which were too long for two of them to be handled on the standard 89' TTX flatcar; they proved unsatisfactory in service because the two-axle design rode very poorly, with a strong tendency to "hunt" above a certain speed. When being moved empty, any bunching of slack could lift them right off the rails. One contributor reported that the Southern Pacific had a policy of accepting them in interchange (which they were required to do) but immediately reloading the trailer on a standard TTX car and returning the TTOX to the carrier which delivered it to them. They were all scrapped by the early 1990's except for one which was rescued and is now at the National Museum of Transport at St. Louis.
