Have you ever wondered how railroad tracks are maintained and upgraded?In "Laying Welded Rail, you'll see a railroad transformed from a 25 mph line with jointed rail to a 50mph line with smooth, welded rail. You'll see the entire process including:
• Dropping off the rail
• Undercutting
• Tamping
• Tie inserting
• Welding the rail together
• Surfacing

A great look at the rebuilding of a railroad line from the ground up.
