Train movements will not be stopped during blackouts, but when blackout signals are heard, or blackouts are indicated by extinguished street or other lights, trains will proceed at maximum speed of 15 MPH, dimming headlights. Where rules or special instructions require a lower speed than 15 MPH, the lower speed will be observed. When engine is provided with storm curtains same will be drawn, all cab lights extinguished, and enginemen will, as far as possible, endeavor to prevent flashes from fire box.

              Passenger trainmen will see that all shades are pulled down. in passenger cars during night hours whether blackout is in effect or not, but during blackout periods, the lights in passenger equipment will be dimmed or turned out, as far as possible, leaving only sufficient light to permit trainmen and passengers to move through cars without injury.

              Rear end marker lights and flagman's lanterns must be kept lighted at all times on both passenger and freight trains. Flagman's lanterns must be shielded while running to prevent being seen. On both passenger and freight trains, in observing requirements of Rule 99, flagman must carry full flagging equipment, shielding lights as much as possible from unnecessary exposure.

              In yards when blackout signals are heard, or blackout is indicated by extinguished street or other lights, engines will, as promptly as possible, clear main track and extinguish headlight and all other engine cab lights, and if engines are equiped with storm curtains same will be drawn. Enginemen will hold spot fire in engine and avoid any flashes of fire. When in clear, trainmen will extinguish hand lanterns and go on spot until "all clear'' signal is sounded, at which time normal operations will be resumed.

              Warning signal will be fluctuating or warbling signal of two minutes duration and the "all clear" signal will be a continuous signal at a steady pitch for a similar period.
