As used in this section qualified person means either a designated supervisor of locomotive engineers or a certified train service engineer determined by the controlling railroad to have the necessary knowledge concerning the controlling railroad's operating rules and to have the necessary operating skills including familiarity with its physical characteristics concerning the joint operations territory.(f) A railroad that is responsible for controlling the conduct of joint operations with another railroad may permit a certified locomotive engineer to operate a locomotive in any class of train or engine service without determining that the person has been certified as a qualified locomotive engineer for the purposes of joint operations when a minimal joint operation is involved. For the purposes of this section a minimal joint operation exists when a locomotive or train belonging to one railroad is being operated on the same track on which operations are conducted by the railroad controlling operations, under the following conditions: (1) The maximum authorized speed for operations on the track does not exceed 20 miles per hour;(2) The track is other than a main track;(3) Operations are conducted under operating rules that require every locomotive and train to proceed at a speed that permits stopping within one half the range of vision of the locomotive engineer; and(4) The maximum distance for joint operations on the track does not exceed one mile.56 FR 28254, June 19, 1991, as amended at 58 FR 19003, Apr. 9, 1993; 64 FR 60993, Nov. 8, 1999
