ProCurve Glass supplied six curved laminated FRA I windshields for locomotives owned by Texas Central Business Lines. This glass has been tested at an independent laboratory according to the requirements found in 49 Code of Federal Regulations Part 223, Safety Glazing Standards—Locomotives, Passenger Cars and Cabooses. This regulation contains ballistics and large object impact tests.
The FRA I windshields supplied to Texas Central Business Lines withstood one shot from a 22-caliber long rifle lead bullet of 40 grains in weight traveling at a maximum velocity of 960 feet per second, as well as a corner impact of a 24-pound cinder block (8 inches x 8 inches x 16 inches) at a minimum velocity of 44 feet/second.
Besides FRA I windshields, ProCurve Glass has also supplied FRA Type II laminates for railcars requiring side-facing glazing. The ballistics requirements for FRA Type II glazing are similar to FRA I, however, the large object impact test from the cinder block requires a minimum velocity of 12 feet/second.
