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.
