Sec. 201.12  Standard for locomotive operation under moving conditions.

    (a) Commencing December 31, 1976, no carrier subject to this 
regulation may operate any locomotive or combination of locomotives to 
which this regulation is applicable, and of which manufacture is 
completed on or before December 31, 1979, which produces A-weighted 
sound levels in excess of 96 dB when moving at any time or under any 
condition of grade, load, acceleration, or deceleration, when measured 
in accordance with the criteria specified in Subpart C of this 
regulation with fast meter response at 30 meters (100 feet) from the 
centerline of any section of

track having less than a two (2) degree curve (or a radius of curvature 
greater than 873 meters (2865 feet)).
    (b) No carrier subject to this regulation may operate any locomotive 
or combination of locomotives to which this regulation is applicable, 
and of which manufacture is completed after December 31, 1979, which 
produce A-weighted sound levels in excess of 90 dB when moving at any 
time or under any condition of grade, load, acceleration, or 
deceleration, when measured in accordance with the criteria specified in 
Subpart C of this part with fast meter response at 30 meters (100 feet) 
from the centerline of any section of track having less than a two (2) 
degree curve (or a radius of curvature greater than 873 meters (2,865 
feet)).
    (c) Commencing January 15, 1984, no carrier subject to this 
regulation may operate any switcher locomotive or a combination of 
switcher locomotives to which this regulation is applicable, and of 
which manufacture is completed on or before December 31, 1979 which 
produce A-weighted sound levels in excess of 90 dB when moving at any 
time or under any condition of grade, load, acceleration or 
deceleration, and when measured in accordance with the criteria in 
Subpart C of this part with fast meter response at 30 meters (100 feet) 
from the centerline of any section of track having less than a two (2) 
degree curve (or a radius of curvature greater than 873 meters (2,865 
feet)). All switcher locomotives that operate in a particular railroad 
facility are deemed to be in compliance with this standard if the A-
weighted sound level from stationary switcher locomotives, singly or in 
combination with other stationary locomotives, does not exceed 65 dB 
when measured with fast meter response at any receiving property 
measurement location near that particular railyard facility and when 
measured in accordance with Subpart C of this regulation.
