Trailer-on-flatcar

Have you ever seen a really big truck carrying lots of smaller cars? Well, a trailer-on-flatcar is kind of like that, but with trains instead of trucks!

A trailer-on-flatcar, or TOFC for short, is a way of transporting freight using trains. First, a big train car called a flatcar is loaded onto the train tracks. This flatcar is like a big, flat platform that doesn't move on its own.

Next, a big trailer is loaded onto the flatcar. This trailer is like a really big box on wheels that can hold lots of stuff. The trailer is then secured to the flatcar so that it doesn't move around during the train ride.

Finally, the train starts moving and the flatcar with the trailer on top is pulled along the tracks. This way, the big trailer can be transported across long distances without needing its own engine or driver.

Why is this helpful? Well, it's much more efficient and cost-effective than having each trailer have to drive itself to its destination. Plus, trains can carry a lot more weight than trucks, which means more stuff can be transported at once.

So, in short, a trailer-on-flatcar is a way of moving big trailers on top of a flat train car so they can travel long distances efficiently and cost-effectively.
