B&O/C&O Operating Rules 1969 - Interlocking Rules
Interlocking Rules
605. At locations designated by special instructions,
interlocking signals govern the use of the blocks
and routes of an interlocking, and as to movements within interlocking
limits, their indications supersede the superiority of trains.
605-A. Trains or engines must not enter or foul
the main track or other signalled track where these rules are in effect
nor cross over from one such track to another, except as governed by
signal idication or on permission of the Train Dispatcher, obtained by
the Conductor or Engineer.
Permission of the Train Dispatcher to hand-operate
a switch to enter main track, or other signalled track, does not
relieve employe of compliance with Rule 505 unless interlocking signal
is provided to govern movement.
Switching movements against the current of traffic
beyond interlocking limits must not be made without permission of the
Train Dispatcher and then only under flag protection or train order.
