49 CFR 219.403 - Requirements for reasonable cause testing.
Each railroad's decision process regarding whether reasonable cause testing is authorized must be completed before the reasonable cause testing is performed and documented according to the requirements of § 219.405. The following circumstances constitute reasonable cause for the administration of alcohol and/or drug tests under the authority of this subpart.
(a)Train accident or train incident. A regulated employee has been involved in a train accident or train incident (as defined in § 219.5) reportable under part 225 of this chapter, and a responsible railroad supervisor (as defined in § 219.5) has a reasonable belief, based on specific, articulable f acts, that the individual employee's acts or omissions contributed to the occurrence or severity of the accident; or
(1) Noncompliance with a train order, track warrant, track bulletin, track permit, stop and flag order, timetable, signal indication, special instruction or other directive with respect to movement of railroad on-track equipment that involves -
(i) Occupancy of a block or other segment of track to which entry was not authorized;
(ii) Failure to clear a track to permit opposing or following movements to pass;
(iii) Moving across a railroad crossing at grade without authorization; or
(iv) Passing an absolute restrictive signal or passing a restrictive signal without stopping (if required);
(2) Failure to protect on-track equipment, including leaving on-track equipment fouling an adjacent track;
(3) Operation of a train or other speedometer-equipped on-track equipment at a speed that exceeds the maximum authorized speed by at least 10 miles per hour or by 50% of such maximum authorized speed, whichever is less;
(4) Alignment of a switch in violation of a railroad rule, failure to align a switch as required for movement, operation of a switch under on-track equipment, or unauthorized running through a switch;
(5) Failure to restore and secure a main track switch as required;
(6) Failure to apply brakes or stop short of a derail as required;
(7) Failure to secure a hand brake or failure to secure sufficient hand brakes, as required;
(8) Entering a crossover before both switches are lined for movement or restoring either switch to normal position before the crossover movement is completed;
(9) Failure to provide point protection by visually determining that the track is clear and giving the signals or instructions necessary to control the movement of on-track equipment when engaged in a shoving or pushing movement;
(10) In the case of a person performing a dispatching function or block operator function, issuance of a mandatory directive or establishment of a route that fails to provide proper protection for on-track equipment;
(11) Interference with the normal functioning of any grade crossing signal system or any signal or train control device without first taking measures to provide for the safety of highway traffic or train operations which depend on the normal functioning of such a device. Such interference includes, but is not limited to, failure to provide alternative methods of maintaining safety for highway traffic or train operations while testing or performing work on the devices or on track and other railroad systems or structures which may affect the integrity of the system;
(12) Failure to perform stop-and-flag duties necessary as a result of a malfunction of a grade crossing signal system;
(13) Failure of a machine operator that results in a collision between a roadway maintenance machine and on-track equipment or a regulated employee;
(14) Failure of a roadway worker-in-charge to notify all affected employees when releasing working limits;
(16) Failure to ascertain that provision was made for on-track safety before fouling a track;
(17) Improper use of individual train detection in a manual interlocking or control point; or
(18) Failure to apply three point protection (fully apply the locomotive and train brakes, center the reverser, and place the generator field switch in the off position) that results in a reportable injury to a regulated employee.
