Sec. 220.51  Radio communications and signal indications.



    (a) No information may be given by radio to a train or engine crew 

about the position or aspect displayed by a fixed signal. However, a 

radio may be used by a train crew member to communicate information 

about the position or aspect displayed by a fixed signal to other 

members of the same crew.

    (b) Except as provided in the railroad's operating rules, radio 

communication shall not be used to convey instructions which would have 

the effect of overriding the indication of a fixed signal.
