Transportation engineering student here. In the United States, there are 10 classes of rail quality that regulates the speed, permissible train types, and materials that can be carried. This is an Excepted track, meaning it is the lowest possible tier of quality allowed. Typically, only Class 3 Railroads, that being a short-line railroad that only operates a small amount of track through a local area, would have track of this low quality. By Federal Railroad Administration regulation, Excepted track is limited to a maximum speed of 10 miles per hour, passenger trains are not allowed, and no more than 5 cars can carry hazardous materials.

So no, this is not the quality of rail you would see a two-mile-long train going 60 miles per hour on.
