§ 243.5 Definitions.
As used in this part—
Administrator means the Administrator of the Federal Railroad Administration or the Administrator's delegate.
Associate Administrator means the Associate Administrator for Railroad Safety and Chief Safety Officer of the Federal Railroad Administration or that person's delegate as designated in writing.
Calendar year means the period of time beginning on January 1 and ending on December 31 of each year.
Contractor means a person under contract with a railroad, including, but not limited to, a prime contractor or a subcontractor.
Designated instructor means a person designated as such by an employer, training organization, or learning institution, who has demonstrated an adequate knowledge of the subject matter under instruction and, where applicable, has the necessary experience to effectively provide formal training on the subject matter. The designated instructor is not required to be an employee of the employer. Employers are required to ensure that employees and non-employees used as designated instructors have the necessary knowledge, skills, and abilities to provide sound coaching, mentoring, and guidance to new learners.
Employer means a railroad or a contractor of a railroad that employs at least one safety-related railroad employee.
Formal training means training that has a structured and defined curriculum, and which provides an opportunity for training participants to have questions timely answered during the training or at a later date. In the context of this part, formal training may include, but is not limited to, classroom, computer-based, correspondence, on-the-job, simulator, or laboratory training.
Knowledge-based training is a type of formal training that is not task-based and is intended to convey information required for a safety-related railroad employee to comply with Federal railroad safety laws, regulations, and orders, as well as any relevant railroad rules and procedures promulgated to implement those Federal railroad safety laws, regulations, and orders.
On-the-job training (OJT) means job training that occurs in the workplace, i.e., the employee learns the job while doing the job.
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 providing goods or services to a railroad; and any employee of such owner, manufacturer, lessor, lessee, or independent contractor.
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, will not be considered a plant railroad because the performance of such activity makes the operation part of the general railroad system of transportation.
Qualified means that a person has successfully completed all instruction, training, and examination programs required by both the employer and this part, and that the person, therefore, may reasonably be expected to proficiently perform his or her duties in compliance with all Federal railroad safety laws, regulations, and orders.
Refresher training means periodic retraining required for each safety-related railroad employee that is designed to maintain, improve, and update the skills and knowledge of existing employees to ensure they are sufficiently acquainted with any changed standards, or any relevant problematic issues or new skills, methods, and processes, and to ensure no important skills or knowledge have been lost due to lack of use. Similar training programs or plans required elsewhere in this chapter but identified by a term other than refresher training such as “recurrent training,” “re-training,” “periodic training,” “training that occurs periodically,” or “training that is required within defined intervals,” are considered refresher training for purposes of this part although they need not be submitted for review pursuant to § 243.103(b).
Safety-related duty means either a safety-related task or a knowledge-based prohibition that a person meeting the definition of a safety-related railroad employee is required to comply with, when such duty is covered by any Federal railroad safety law, regulation, or order.
Safety-related railroad employee means an individual who is engaged or compensated by an employer to:
(1) Perform work covered under the hours of service laws found at 49 U.S.C. 21101, et seq.;
(2) Perform work as an operating railroad employee who is not subject to the hours of service laws found at 49 U.S.C. 21101, et seq.;
(3) In the application of parts 213 and 214 of this chapter, inspect, install, repair, or maintain track, roadbed, and signal and communication systems, including a roadway worker or railroad bridge worker as defined in § 214.7 of this chapter;
(4) Inspect, repair, or maintain locomotives, passenger cars or freight cars;
(5) Inspect, repair, or maintain other railroad on-track equipment when such equipment is in a service that constitutes a train movement under part 232 of this chapter;
(6) Determine that an on-track roadway maintenance machine or hi-rail vehicle may be used in accordance with part 214, subpart D of this chapter, without repair of a non-complying condition;
(7) Directly instruct, mentor, inspect, or test, as a primary duty, any person while that other person is engaged in a safety-related task; or
(8) Directly supervise the performance of safety-related duties in connection with periodic oversight in accordance with § 243.205.
Safety-related task means a task that a person meeting the definition of a safety-related railroad employee performs, when such task is covered by any Federal railroad safety law, regulation, or order.
Task-based training means a type of formal training with a primary focus on teaching the skills necessary to perform specific tasks that require some degree of neuromuscular coordination.
Tourist, scenic, historic, or excursion operations that are not part of the general railroad system of transportation means a tourist, scenic, historic, or excursion operation conducted only on track used exclusively for that purpose (i.e., there is no freight, intercity passenger, or commuter passenger railroad operation on the track).
Training organizations or learning institutions mean entities that provide training services for people who are safety-related railroad employees or independent students who will rely on the training services provided to qualify to become safety-related railroad employees, but not employees of the entities providing the training. Training organizations and learning institutions include businesses that provide formal training, and colleges and universities that provide rail safety courses, necessary for a person to qualify as a safety-related railroad employee. Training organizations and learning institutions also include entities that do not maintain fixed facilities (i.e., do not have a physical location), as they may rent or lease meeting space to deliver formal training, deliver formal training at an employer's facility, or deliver computer-based training virtually. A railroad that trains its own employees and also trains safety-related railroad employees of other employers is not a training organization or learning institution.
