Ineligible or ineligibility means that a person is legally disqualified from serving as a certified signal employee. The term covers a number of circumstances in which a person may not serve as a certified signal employee. Revocation of certification pursuant to § 246.307 and denial of certification pursuant to § 246.301 are two examples in which a person would be ineligible to serve as a certified signal employee. A period of ineligibility may end when a condition or conditions are met, such as when a person meets the conditions to serve as a certified signal employee following an alcohol or drug violation pursuant to § 246.115.
Knowingly means having actual knowledge of the facts giving rise to the violation or that a reasonable person acting in the circumstances, exercising due care, would have had such knowledge.
Medical examiner means a person licensed as a doctor of medicine or doctor of osteopathy. A medical examiner can be a qualified full-time salaried employee of a railroad, a qualified practitioner who contracts with the railroad on a fee-for-service or other basis, or a qualified practitioner designated by the railroad to perform functions in connection with medical evaluations of employees. As used in this rule, the medical examiner owes a duty to make an honest and fully informed evaluation of the condition of an individual.
Mentor means a certified signal employee who has at least one year of experience as a certified signal employee. For purposes of this part, a mentor provides direct and immediate supervision over the work of one or more signal employees.
On-the-job training 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 or subcontractor providing goods or services to a railroad; and any employee of such owner, manufacturer, lessor, lessee, or independent contractor or subcontractor.
Physical characteristics means the actual track profile of and physical location for points within a specific yard or route that affect the movement of a locomotive or train. Physical characteristics includes how signal systems and related technology are deployed within the territory, for purposes of this part.
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 a person who has successfully completed all instruction, training and examination programs required by the railroad, and the applicable parts of this chapter and that the person therefore may reasonably be expected to be proficient on all safety related tasks the person is assigned to perform.

If a railroad does not have designated employee representation, then a person employed by the railroad need not comply with paragraph (2) or (3) of this definition to be a qualified instructor.
Railroad means any form of nonhighway ground transportation that runs on rails or electromagnetic guideways and any entity providing such transportation, including:
Railroad officer means any supervisory employee of a railroad.
Serve or service, in the context of serving documents, has the meaning given in Rule 5 of the Federal Rules of Civil Procedure as amended. Similarly, the computation of time provisions in Rule 6 of the Federal Rules of Civil Procedure as amended are also applicable in this part. See also the definition of "filing" in this section.
Signal employee means, for purposes of this part, a person who is engaged in installing, troubleshooting, testing, repairing, or maintaining railroad signal systems or related technology.
Signal instructor means, for purposes of this part, a person who has demonstrated, pursuant to the railroad's written signal employee certification program, an adequate knowledge of the subject matter under instruction and has the necessary experience to effectively provide formal training of the subject matter.
Signal system, for purposes of this part, includes software and equipment for the following: block signal systems, cab signal systems, train control systems, positive train control systems, highway-rail and pathway grade crossing warning systems, unusual contingency detection devices, power-assisted switches, broken rail detection systems, switch point indicators, as well as other safety-related devices, appliances, technology, and systems installed on the railroad in signaled or non-signaled territory.
Substance abuse disorder refers to a psychological or physical dependence on alcohol or a drug, or another identifiable and treatable mental or physical disorder involving the abuse of alcohol or drugs as a primary manifestation. A substance abuse disorder is "active" within the meaning of this part if the person is currently using alcohol or other drugs, except under medical supervision consistent with the restrictions described in § 219.103 of this chapter or has failed to successfully complete primary treatment or successfully participate in aftercare as directed by a DAC or SAP.
Substance Abuse Professional (SAP) means a person who meets the qualifications of a substance abuse professional, as provided in 49 CFR part 40.
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).
Unusual contingency detection device means a device used in the detection of defective conditions on locomotives and rolling stock (e.g., high-wide load, hot or defective bearing, defective wheel detectors) or other unsafe environmental conditions (e.g., high-water, high wind, sliding or slumping soil, rock or snow slide detectors). These devices need not be connected to a signal system for this part to apply.
