track, operations may continue at Class 1 speeds for a period of not 
more than 30 days without bringing the track into compliance, under the 
authority of a person designated under Sec. 213.7(a), who has at least 
one year of supervisory experience in railroad track maintenance, after 
that person determines that operations may safely continue and subject 
to any limiting conditions specified by such person.
