Here is a link to a video that shows how the concrete ties and rail are put in place.

The road bed was raised 13 inches to accommodate the new high speed rail line between St. Louis, MO and Chicago, IL.

There are only two of these track laying machines in the world, one here and one in Europe.

What would the laborers who laid the first cross country tracks think if they could see this?
