a. Train Operational Methods.
(1) Yard Limit Rules. The Installation Commander may designate yards in their local
railroad operating directive. Examples are classification yards, commercial-government
interchange yards (bullpen), and holding yards. The following yard rules shall apply to all trains
operating within a rail yard.
Yard shall be marked, for example, upon entering the yard, a sign stating "yard
rules apply" and upon exiting, a sign stating "main line rules apply."
While operating within yard limits, trains or locomotives shall not exceed a
speed which will enable the train or locomotive to stop short of another train
or locomotive, obstruction, or switch not properly lined. Trains or
locomotives operating within yards shall not exceed 10 MPH or a lesser speed
as designated by a local SOP.
(2) Main Track Rules. Main track shall only exist where access is controlled by
means of a railroad dispatcher.
Operations shall follow the guidelines of only one train in each absolute block. The railroad
dispatcher shall not allow any train or locomotive to occupy a block previously occupied by
another train or locomotive until the dispatcher has positive confirmation from the conductor or
engineer that the original train or locomotive is no longer in the block.
Trains shall only be allowed to enter the same block if controlled by train order rules or positive
signal protection or both. Flagging protection is necessary.
b. Train Crew Notices. Train crew notices are necessary to provide a means of alerting
crews to local situations that arise which are not covered by other directives. They describe
situations that may be present for any period of time. Examples of these situations include: out
of service track, slow orders, wash outs, track under repair, and inactive track These situations
often present hazards that crews need to be aware of to operate safely. Notices shall be kept
up-to-date and reviewed daily. They shall be issued on an as-needed basis.
Crew members shall sign the log sheet that accompanies the train crew notice before every shift
and they shall note the highest notice number present. See Appendix B for samples (Form 2,
TRAIN CREW NOTICE and Form 3, TRAIN CREW NOTICE ACKNOWLEDGEMENT
One system for maintaining train crew notices is to use an electronic print board. Key safety
related information is entered on the print board as required. Railroad personnel at the beginning
of their shift acknowledge they have done so with their signatures on the board. When all have
read and signed, the rail supervisor prints the board. The copy provides a record of key
information and the signature of the personnel who have read the information.
Train crew notices should be numbered consecutively beginning with January 1st of each year and
issued and canceled by the transportation supervisor or other designated officer.
