Blue signals (3) can take several forms. Many engine terminals
have blue electric lights permanently installed along tracks
where engines are serviced. Depending on the era, it can also
be a blue lantern hung on the equipment, or a cloth flag or
metal panel.
When a blue signal is placed to protect workers and equipment
not on a main track, it continues, “switches providing direct
access must be lined against movement to that track, secured by
an effective locking device and a blue signal must be placed at
or near such switch. Facing point crossover switch must be lined
against a crossover movement and secured by an effective lock-
ing device.”
Sub-sections set out rules for positioning derail devices, and for
securing remote control switches.
Lettering on flags and panels can vary according to the situ-
ation. Most have some variation on “STOP: Men at Work,”
but they might also have a plain “STOP,” “STOP – Tank Car
Connected,” “Occupied Camp Car” or something else. The
rules are the same for all.
