Note: Unit Cost = 0/rail. Estimate based
on 33-ft sections of 90 lb. rail, and allowance
of four defective rails/mile.
5) Rebuild Road Crossings
In road crossings that require replacement, the track often needs to be completely rebuilt. In addition,
conventional rail joints are often replaced with welded joints to eliminate the need for future joint
maintenance (which usually requires tearing out at least part of the crossing surface). Welding joints in a
crossing is especially recommended in areas with heavy truck traffic and in crossings in main running
These estimates cover crossing replacements, as listed in table D-3. Three types are specified: complete
track rebuild with timber/asphalt surface, timber/asphalt surface replacement, and timber/gravel surface
replacement.
