either direction on the main line. Engineers shall also dim lights when approaching motor vehicles
operating along parallel roadways.
(5) End of Train Markers. The lead car in the direction of travel shall be properly
protected by the train crew. For all train movements made between sunset and sunrise or during
low-visibility conditions such as rain, snow or fog, a battery-powered flashing light should be
placed on the lead or trailing coupler of the last car. Short yard switching type movements do not
require the use of the end of train light.
(6) Highway Crossings (Grade crossing). For crossings with approach activated lights
and gates, the crew shall confirm that the lights are flashing and the gates are down before
proceeding across the crossing. For crossings with approach activated lights only, the crew shall
confirm that the lights are flashing (and have done so for at least 20 seconds) before proceeding
across the crossing. Horn and bell procedures shall be followed. Sound the horn 20 seconds
before the train will occupy the crossing, which translates to the following distances for the
5 MPH.......... 150 feet
20 MPH........ 600 feet
10 MPH.......... 300 feet
25 MPH........ 750 feet
15 MPH.......... 450 feet
30 MPH........ 900 feet
Any lights that are observed as not flashing shall be reported immediately to the railroad
When a train in a switching movement has been delayed or has stopped within 200 feet of a public
crossing protected by automatic crossing signals, the crossing shall not be occupied by either a
forward or reverse movement unless crossing signals have been operating for 20 seconds to
The Installation Commander will designate crossings which must be flagged and shall be included
in the local railroad operating directive. When flagging is not used, horn and bell procedures shall
When cars are shoved in a switching movement over a highway crossing, a member of the crew
shall flag the crossing per Section 3.3.f.
When visibility is restricted at a highway crossing by cars on an adjacent track, the crossing shall
be flagged per Section 3.3.f.
(7) Blue Signals (Flags and Lights). Blue signals are important in maintaining a safe
railroad operation. Blue signals indicate that someone is working in, on, under, between or
around the equipment and no movement of that equipment shall be made. Violation of the blue
signal rule can put one or more workers at risk of death or serious injury.
