Re: Lobato Bridge Reconstruction Report

I skimmed the history part and read the trades part. I think this is a rather important account to keep, documenting both the 'was' and the 'is' of the bridge as it transitioned from it's original configuration to what it is post-repair.

The section, "Bridge Analysis and Rating" is interesting, particularly this statement: " Results of the rating analysis deter-mined that the bridge in its pre-fire condition was overstressed from 20 to 30 percent when loaded by the current trains at the bridge spans and at two of the tallest bridge bents." If you read a bit before this they describe the load conditions, two trains a day, max speed of 8mph, pulled by a K-27 or K-28. Supports the "no double-heading" restriction. What's not said in the report is how the new design affects the overstress condition of the old design...
