Video from July 2015

This in Fostoria, Ohio at the Iron Triangle where the NS tracks cut across a CSX junction at an angle, forming a triangle.

The train in this video is called a RoadRailer. A truck (a set of train wheels) is put under the rear end of each trailer and the trailers are connected together with a metal bar.

The train was waiting down the track for a while because the junction was busy. You can see it start up and head across one of the three diamonds that make up the corners of the Iron Triangle. The two other corners of the triangle are shown at 3:14 and 5:01.
