(1) Operate a locomotive or train past a signal indication, excluding a hand or a radio signal indication or a switch, that requires a complete stop before passing it;  or

(2) Operate a locomotive or train at a speed which exceeds the maximum authorized limit by at least 10 miles per hour. Where restricted speed is in effect, only those violations of the conditional clause of restricted speed rules (i.e., the clause that requires stopping within one half of the locomotive engineer's range of vision), or the operational equivalent thereof, which cause reportable accidents or incidents under part 225 of this chapter, shall be considered instances of failure to adhere to this section;  or

(3) Operate a locomotive or train without adhering to procedures for the safe use of train or engine brakes when the procedures are required for compliance with the Class I, Class IA, Class II, Class III, or transfer train brake test provisions of 49 CFR part 232 or when the procedures are required for compliance with the class 1, class 1A, class II, or running brake test provisions of 49 CFR part 238;
