    In this section, before clause (1), the text of 49 App.:26(c) (words 
before 2d proviso) is omitted as executed. The words ``The Secretary of 
Transportation may amend . . . change'' are substituted for ``and 
approved by the Secretary of Transportation'' and ``the Secretary may . 
. . revise, amend, or modify'' for clarity and to eliminate unnecessary 
words. The words ``regulation or . . . a requirement applicable to a 
railroad carrier for installing, maintaining, inspecting, or repairing a 
signal system under this chapter'' are substituted for ``rules, 
standards, and instructions herein provided for'' and ``rules, 
standards, and instructions prescribed by him under this subsection'' 
for clarity, for consistency in the revised title, and because of the 
restatement. Clause (1) is substituted for ``such railroad may from time 
to time change . . . but such change shall not take effect and the new 
rules, standards, and instructions be enforced until they shall have 
been filed with'' for clarity and to eliminate unnecessary words. The 
words ``and as revised, amended, or modified they shall be obligatory 
upon the railroad after a copy thereof shall have been served as above 
provided'' are omitted as being superseded by 5:ch. 5, subch. II.
