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.

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.

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.

(1) Commuter or other short-haul railroad passenger service in a metropolitan or suburban area and commuter railroad service that was operated by the Consolidated Rail Corporation on January 1, 1979; and

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.
