FRA means the Federal Railroad Administration.
FRA Associate Administrator means the Associate Administrator for Railroad Safety and Chief Safety Officer, Federal Railroad Administration, or the Associate Administrator's delegate.
Fully implemented means that all elements of an RRP as described in the RRP plan are established and applied to the safety management of the railroad.
Hazard means any real or potential condition that can cause injury, illness, or death; damage to or loss of a system, equipment, or property; or damage to the environment.
Inadequate safety performance means safety performance that FRA has determined to be inadequate based on the criteria described in § 271.13 .
Mitigation strategy means an action or program intended to reduce or eliminate the risk associated with a hazard.
Person means an entity of any type covered under 49 U.S.C. 21301 , including, but not limited to, the following: A railroad; a manager, supervisor, official, or other employee or agent of a railroad; any owner, manufacturer, lessor, or lessee of railroad equipment, track, or facilities; any independent contractor or subcontractor providing goods or services to a railroad; any employee of such owner, manufacturer, lessor, lessee, or independent contractor or subcontractor.
Pilot project means a limited scope project used to determine whether quantitative evaluation and analysis suggests that a particular system or mitigation strategy has potential to succeed on a full-scale basis.
Plant railroad means a plant or installation that owns or leases a locomotive, uses that locomotive to switch cars throughout the plant or installation, and is moving goods solely for use in the facility's own industrial processes. The plant or installation could include track immediately adjacent to the plant or installation if the plant railroad leases the track from the general system railroad and the lease provides for (and actual practice entails) the exclusive use of that trackage by the plant railroad and the general system railroad for purposes of moving only cars shipped to or from the plant. A plant or installation that operates a locomotive to switch or move cars for other entities, even if solely within the confines of the plant or installation, rather than for its own purposes or industrial processes, is not considered a plant railroad because the performance of such activity makes the operation part of the general railroad system of transportation.
Positive train control system means a system designed to prevent train-to-train collisions, overspeed derailments, incursions into established work zone limits, and the movement of a train through a switch left in the wrong position, as described in subpart I of part 236 of this chapter.
