81. Cab aprons.(a) General provisions.Cab aprons shall be of proper length and width to ensure safety. Cab aprons shall be securelyhinged, maintained in a safe and suitable condition for service, and roughened, or otherprovision made, to afford secure footing.(b) Width of apron.The cab apron shall be of a sufficient width to prevent, when the drawbar is disconnected andthe safety chains or the safety bars are taut, the apron from dropping between the steamlocomotive and tender.82. Fire doors.(a) General provisions.Each steam locomotive shall have a fire door which shall latch securely when closed andwhich shall be maintained in a safe and suitable condition for service. Fire doors on all oilburninglocomotives shall be latched securely with a pin or key.(b) Mechanically operated fire doors.Mechanically operated fire doors shall be so constructed and maintained that they may beoperated by pressure of the foot on a pedal, or other suitable appliance, located on the floor ofthe cab or tender at a suitable distance from the fire door, so that they may be convenientlyoperated by the person firing the steam locomotive.(c) Hand-operated doors.Hand operated fire doors shall be so constructed and maintained that they may beconveniently operated by the person firing the steam locomotive.83. Cylinder cocks.Each steam locomotive shall be equipped with cylinder cocks which can be operated from the cabof the steam locomotive. All cylinder cocks shall be maintained in a safe and suitable condition forservice.84. Reset safety controlsEach steam locomotive will be equipped with a rest safety control system of a design that is similarto that used on traditional locomotives.Records shall be maintained on the design and installation of such a system and will be madeavailable to affected railway companies and government agencies upon reasonable request.Operation of the reset safety control system will be made part of the training for qualifiedoperators.
85. Audible warning device.(a) General provisions.Each steam locomotive shall be equipped with an audible warning device that produces a minimumsound level of 96db(A) at 100 feet in front of the steam locomotive in its direction of travel. Thedevice shall be arranged so that it may conveniently be operated by the engineer from his or hernormal position in the cab.(b) Method of measurement.Measurement of the sound level shall be made using a sound level meter conforming, at aminimum, to the requirements of ANSI S1.4-1971, Type 2, and set to an A-weighted slowresponse. While the steam locomotive is on level, tangent track, the microphone shall bepositioned 4 feet above the ground at the center line of the track and shall be oriented with respectto the sound source in accordance with the microphone manufacturer's recommendations.86. Required illumination.(a) General provisions.Each steam locomotive used between sunset and sunrise shall be equipped with an operableheadlight that provides illumination sufficient for a steam locomotive engineer in the cab to see, ina clear atmosphere, a dark object as large as a man of average size standing at least 800 feet aheadand in front of such headlight. If a steam locomotive is regularly required to run backward for anyportion of its trip other than to pick up a detached portion of its train or to make terminalmovements, it shall also be equipped on its rear end with an operable headlight that is capable ofproviding the illumination described in this paragraph (a).(b) Dimming device.Such headlights shall be provided with a device whereby the light from same may be diminished inyards and at stations or when meeting trains.(c) Ditch lights.Each steam locomotive used in a lead position and operated at more than 25 mph over public gradecrossings will be equipped with 2 ditch lights of similar intensity and mounted so as to be facing inthe normal direction of travel and at locations similar to those used on traditional locomotives.(i) Where multiple locomotives utilized.When two or more locomotives are used in the same train, the leading locomotive only will berequired to display a headlight and ditch lights.87. Cab lights.Each steam locomotive shall have cab lights that sufficiently illuminate the control instruments,meters and gauges to allow the engine crew to make accurate readings from their usual and properpositions in the cab. These lights shall be so located and constructed that the light will shine onlyon those parts requiring illumination and does not interfere with the engine crew's vision of thetrack and signals. Each steam locomotive shall also have a conveniently located additional lamp
