Answer: Move in either direction between MP 50 and MP 60.

A train is operating within Yard Limits. What is the primary method of authorizing movement on the main track within these limits?
Answer: The presence of a 'Yard Limit' sign itself serves as authority.
GCOR Rule 6.13, 'Yard Limits,' states that within yard limits, trains or engines are authorized to use the main track not protecting against other trains or engines. The rule itself, indicated by timetable and signs, provides the authority, with the key stipulation that all movements must be made at restricted speed.
A train crew is instructed by a Track Bulletin Form B to protect against men and equipment between MP 10 and MP 12. Upon approaching the limits, what is the first required action?

A train has been given authority to proceed on a main track where a block system is in effect. If the train stops or its speed is reduced below 10 MPH after passing a proceed signal, what action is required by GCOR Rule 9.9?
Answer: Proceed at restricted speed until the next signal is visible and displays a proceed indication.
GCOR Rule 9.9, 'Train Delayed Within a Block,' specifies that if a train that entered a block on a proceed indication stops or slows below 10 MPH, it must then proceed at restricted speed until the next signal is visible and that signal displays a proceed indication.
