The remaining surfaces of the railroad cars <br />have active corrosion, pitting, flakes, and are brownish in color. The bottom surfaces of the lower flanges of the main girders have the <br />most pitting and the paint system has almost completely flaked off. The longitudinal girders and their web stiffeners have active <br />corrosion and pitting. The transverse beams have active corrosion on their surfaces. Section loss from active corrosion and pitting is <br />less than 1 percent on both railroad cars. <br />The following cracks have been noted in BIRs dating back to 12/03/2003 and there was work done to weld over these cracks. The <br />sizes of these cracks have not changed since they were first noted. The following notes are retained for future reference to check <br />crack propagation: <br />1. A 3.75 inch crack in the web of the main girder of the left railroad car in Bay 1 at midspan. <br />(58) 5DECK RATING = <br />(36a) Rail Code 0010 <br />304 <br />330 <br />Joint-Open Expansion <br />Railing-Metal <br />2 <br />2 <br />12 <br />34 <br />m <br />m <br /> 12 <br /> 34 <br /> 0 <br /> 0 <br /> 0 <br /> 0 <br /> 0 <br /> 0 <br />JOINT/APPROACH/RAIL ELEMENT INSPECTION RATINGS AND NOTES <br />RAIL INFORMATION <br />(36b) Transition (36c) Appr Guardrail (36d) Appr Guardrail End 25Roadway Speed MPH <br />JOINT - APPROACH - RAIL <br />(304) Joint-Open Expansion <br />(330) Railing-Metal <br />Element DescriptionElem <br />No. <br />Env Total <br />Qty <br />Units <br />CS 1 CS 2 CS 3 CS 4 <br />Qty in each Condition StateDefect/ <br />Prot Defect <br />There were no significant defects noted. <br />There were no significant defects noted.
