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, pursuant to the training program submitted by the employer, training organization, or learning institution, an adequate knowledge of the subject matter under instruction and, where applicable, has the necessary experience to effectively provide formal training of the subject matter.
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 1 U.S.C. 1 , 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.

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).
