Title 49 - Transportation
Effective Date(s): August 28, 2006 2. Amend §229.5 by revising the definition of “remanufactured locomotive” and adding in alphabetical order additional definitions to read as follows: * * * * * AAR means the Association of American Railroads. Anti-climbers means the parts at the ends of adjoining rail vehicles in a train that are designed to engage when subjected to large buff loads to prevent the override of one vehicle by another. Associate Administrator for Safety means the Associate Administrator for Safety, Federal Railroad Administration, or that person's delegate as designated in writing. * * * * * Build date means the date on which the completed locomotive is shipped by the manufacturer or remanufacturer to the customer, or if the railroad manufactures or remanufactures the locomotive itself, the date on which the locomotive is released from the manufacture or remanufacture facility. * * * * * Collision posts means structural members of the end structures of a rail vehicle that extend vertically from the underframe to which they are securely attached and that provide protection to occupied compartments from an object penetrating the vehicle during a collision. Corner posts means structural members located at the intersection of the front or rear surface with the side surface of a rail vehicle and which extend vertically from the underframe to the roof. * * * * * Designated service means exclusive operation of a locomotive under the following conditions: (1) The locomotive is not used as an independent unit or the controlling unit in a consist of locomotives except when moving for the purposes of servicing or repair within a single yard area; (2) The locomotive is not occupied by operating or deadhead crews outside a single yard area; and (3) The locomotive is stenciled “Designated Service—DO NOT OCCUPY.” Design standard means a criterion adopted by an industry or voluntary consensus standards body, which addresses the design of a locomotive with respect to its crashworthiness and crashworthiness features. * * * * * FRA means the Federal Railroad Administration. Fuel tank, external means a fuel containment vessel that extends outside the car body structure of a locomotive. Fuel tank, internal means a fuel containment vessel that does not extend outside the car body structure of a locomotive. * * * * * Lateral means the horizontal direction perpendicular to the direction of travel. * * * * * Locomotive cab means the compartment or space on board a locomotive where the control stand is located and which is normally occupied by the engineer when the locomotive is operated. Longitudinal means in a direction parallel to the normal direction of travel. * * * * * Manufacture means the act of constructing a locomotive. * * * * * Monocoque design locomotive means a locomotive design where the shell or skin acts as a single unit with the supporting frame to resist and transmit the loads acting on the locomotive. * * * * * Narrow-nose locomotive means a locomotive with a short hood that spans substantially less than the full width of the locomotive. Occupied service means the operation of a locomotive when the cab is physically occupied by a person. * * * * * Permanent deformation means the undergoing of a permanent change in shape of a structural member of a rail vehicle. * * * * * Power car means a rail vehicle that propels a Tier II passenger train or is the lead vehicle in a Tier II passenger train, or both. * * * * * Remanufacture means the act of constructing a remanufactured locomotive. Remanufactured locomotive means a locomotive rebuilt or refurbished from a previously used or refurbished underframe (“deck”), containing fewer than 25% previously used components (measured by dollar value of the components). For calculation purposes, the percentage of previously used components is determined with equivalent value of new parts and is calculated using dollar values from the same year as the new parts used to remanufacture the locomotive. Roof rail means the longitudinal structural member at the intersection of the side wall and the roof sheathing. * * * * * Semi-monocoque design locomotive means a locomotive design where the skin or shell acts, to some extent, as a single unit with the supporting frame to resist and transmit the loads acting on the locomotive. Semi-permanently coupled means coupled by means of a drawbar or other coupling mechanism that requires tools to perform the uncoupling operation. * * * * * Short hood means the part of the locomotive above the underframe located between the cab and the nearest end of the locomotive. Standards body means an industry and/or professional organization or association which conducts research and develops and/or issues policies, criteria, principles, and standards related to the rail industry. * * * * * Tier II means operating at speeds exceeding 125 mph but not exceeding 150 mph. * * * * * Ultimate strength means the load at which a structural member fractures or ceases to resist any load. * * * * * Wide-nose locomotive means a locomotive with a short hood that spans the full width of the locomotive.
