\| \| \| \| \| \| \| \| \| \|
govern the approach of a train to a home signal.
\| \| \| \| \| \| \| \| \|
Division Notice (DN): - CORRECT ANSWERS ✔✔A publication

issued periodically by the designated officer, which contains
\| \| \| \| \| \| \|
instructions or information which do not affect the movement of \| \| \| \| \| \| \| \| \| \|
trains.

\| \| \| \| \| \| \| \| \| \|
unlocked only by the class, group or craft of employees that
\| \| \| \| \| \| \| \| \| \| \|
applied it. \|
Electrically Locked Switch: - CORRECT ANSWERS ✔✔A hand-
\| \| \| \| \| \| \|
operated switch equipped with an electrically controlled device
\| \| \| \| \| \| \| \|
that restricts the movement of the switch.
\| \| \| \| \| \|

\| \| \| \| \| \| \| \| \|
employee responsible for establishing protection for a roadway
\| \| \| \| \| \| \| \|
worker or roadway workgroup.
\| \| \|
Engine (Eng): - CORRECT ANSWERS ✔✔A unit or combination of
\| \| \| \| \| \| \| \| \| \|
units propelled by any form of energy and operated from a
\| \| \| \| \| \| \| \| \| \| \|
single control, used in train or yard service. The word "engine"
\| \| \| \| \| \| \| \| \| \| \|
may also be used to identify control cars.
\| \| \| \| \| \| \|
