c(d) Certification. The characters “FRA-224”, constituting the manufacturer’s certification that the retroreflective sheeting conforms to the requirements of paragraphs (a) through (c) of this section, shall appear at least once on the exposed surface of each piece of sheeting in the final application. The characters shall be a minimum of three millimeters high, and shall be permanently stamped, etched, molded, or printed within the product and each certification shall be spaced no more than four inches apart.
(e) Different standards Under 224.15, a railroad or owner of freight rolling stock may petition the Associate Administrator to approve a different safety-enhancing technology. Any such petition must include enough data and analysis to show that the technology will be visible and last at least as long as the sheeting described in paragraphs (a) through (c) applied in accordance with this part. It will also show that the technology will present a recognizable visual target that is in line with freight rolling stock with retroreflective sheeting that meets the technical requirements of this part to give motorists the intended warning.
§224.105 Sheeting dimensions and quantity.
Retroreflective sheeting shall be applied along the length of each railroad freight car and locomotive side as described in §224.106. Unless otherwise specified, retroreflective sheeting applied under this part shall be applied in strips 4 inches wide and 18 or 36 inches long, as practicable. The amount of retroreflective sheeting to be applied to each car or locomotive subject to this part is dependent on the length of the car or locomotive and the color of the sheeting. For purposes of this part, the length of a railroad freight car or locomotive is measured from endsill to endsill, exclusive of the coupler and draft gear. Each side of a railroad freight car subject to this part, including each unit of multi-unit cars, and each side of a locomotive subject to this part must be equipped with at least the minimum amount of retroreflective sheeting specified in Table 2 of this subpart.
1Freight cars or locomotives over 100 ft. in length must be equipped with an additional one-half a square foot of sheeting on each side for every additional 10 feet of length.
§224.106 Location of retroreflective sheeting.
(A) Freight trains on railroads. The Associate Administrator has approved a uniform industry standard that calls for the distribution of material along the length of each car and as near as reasonably possible to 42 inches above the top of rail to be used to apply the retroreflective sheeting along the length of each railroad freight car side. The standards outlined in this subpart must be followed if such a standard is not proposed by business or adopted by the Associate Administrator. The retroreflective sheeting used in accordance with this item must be placed away from any fixtures and equipment, such as pipes, ladders, and other safety appliances, that could obstruct its sight. Bolts, rivets, door hinges, and other discontinuous surfaces that might prevent the retroreflective sheeting from sticking to the car sides are not required to have discontinuous surfaces covered with retroreflective sheeting. Additionally, car stencils and markings that are already present or necessary need not be covered with retroreflective sheeting. 4×18 and 4×36 inch strips of retroreflective material may be cut into 4×9 inch strips and applied on either side of the appurtenance, discontinuous surface, or existing or required car markings or stencils, as is practical, if it is necessary to avoid appurtenances, discontinuous surfaces, or existing or required car markings or stencils. Retroreflective sheeting must be installed along the sides of freight rolling stock, unless otherwise specified, as practically as possible, at intervals not to exceed every 12 feet. Due to existing stencils, adornments, or discontinuous surfaces, it may not be practical to apply retroreflective sheeting every 12 feet. In this case, the sheeting must be applied at the minimum feasible spacing.
(1) General rule. On railroad freight cars other than flat cars and tank cars, retroreflective sheeting shall be applied in either a vertical or horizontal pattern along the length of the car sides, with the bottom edge of the sheeting as close as practicable to 42 inches above the top of rail. Retroreflective sheeting shall not be applied below the side sill.
(i) Vertical application. If retroreflective sheeting is applied in a vertical pattern, at least one 4×36 inch strip or two 4×18 inch strips, one above the other, shall be applied as close to each end of the car as practicable. Between these two vertical end strips, a minimum of one 4×18 inch strip shall be applied at least every 12 feet, as practicable. See Figures 1, 2 and 3.
(ii) Horizontal application. If retroreflective sheeting is applied in a horizontal pattern, at least one 4×36 inch strip, or two 4×18 inch strips, one above or next to the other, shall be applied as close to each end of the car as practicable. Between these end strips, a minimum of one 4×18 inch strip shall be applied at least every 12 feet, as practicable. See Figures 4, 5, and 6.
(2) Tank cars. On tank cars, retroreflective sheeting shall be applied vertically to each car side and centered on the horizontal centerline of the tank, or as near as practicable. If it is not practicable to safely apply the sheeting centered vertically about the horizontal centerline of the tank, the sheeting may be applied vertically with its top edge no lower than the horizontal centerline of the tank. A minimum of either one 4×36 inch strip or two 4×18 inch strips, one above the other, shall be applied as close to each end of the car as practicable. Between these two end strips, a minimum of one 4×18 inch strip shall be applied at least every 12 feet, as practicable. Retroreflective sheeting applied under this part shall not be located in the spillage area directly beneath the manway used to load and unload the tank. See Figures 7 and 8.
(3) Flat cars. On flat cars, retroreflective sheeting shall be applied in a horizontal pattern along the length of the side sill with the bottom edge of the sheeting no lower than the bottom of the side sill and the top edge of the sheeting no higher than the top of the car deck or floor. At least two 4×18 inch strips, one above the other, shall be applied as close to each end of the car as practicable. If the side sill is less than 8 inches wide, one 4×36 inch strip, or two 4×18 inch strips may be applied one next to the other, dividing the strips into nine inch segments as necessary in accordance with paragraph (a) of this section. Between the two end strips, a minimum of one 4×18 inch strip shall be applied at least every 12 feet, as practicable. See Figure 9. If a car has a separate rack structure, retroreflective sheeting may be applied to the flat car portion only in accordance with the requirements of this section. For cars without continuous side sills, retroreflective sheeting may be applied to other surfaces inboard of the sides, such as the center sill, provided that the sheeting is not obscured by other components.
(4) Cars of special construction. This paragraph applies to any car the design of which is not compatible with the patterns of application otherwise provided in this section. Retroreflective sheeting shall conform as closely as practicable to the requirements of paragraphs (a)(1) through (a)(3) of this section and shall have the minimum amount of sheeting described in §224.105 distributed along the length of each car side.
(b) Locomotives. Locomotives subject to this part shall be equipped with at least the minimum amounts of retroreflective sheeting required by §224.105 either in strips four inches wide and 18 or 36 inches long and spaced as uniformly as practicable along the length of the locomotive sides, or in one continuous strip, at least four inches wide, along the length of the locomotive. Retroreflective sheeting applied to locomotive sides shall be applied as close as practicable to 42 inches from the top of the rail.
