the conductor with the most seniority takes charge). All persons employed
on the train must obey the con- ductor's instructions, unless the
instructions endanger the train's safety or violate the rules. If any doubts
arise concerning the authority for proceeding or safety, the conductor must
consult with the engineer who will be equally responsible for the safety
and proper handling of the train.

any restriction placed on equipment being handled.
3. The conductor must remind the engineer that the train is
approaching an area restricted by:
• Limits of authority.

The conductor must inform the engineer after the train passes the last
station, but at least 2 miles from the restriction.

the instruc- tions of the engineer concerning rules, safety, and
protection of the train.
