PART 201--NOISE EMISSION STANDARDS FOR TRANSPORTATION EQUIPMENT; INTERSTATE 
RAIL CARRIERS--Table of Contents
 
         Subpart B--Interstate Rail Carrier Operations Standards
 
Sec. 201.11  Standard for locomotive operation under stationary conditions.

    (a) Commencing December 31, 1976, no carrier subject to this 
regulation shall operate any locomotive 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 93 dB at 
any throttle setting except idle, when operated singly and when 
connected to a load cell, or in excess of 73 dB at idle when operated 
singly, and when measured in accordance with the criteria specified in 
Subpart C of this part with slow meter response at a point 30 meters 
(100 feet) from the geometric center of the locomotive along a line that 
is both perpendicular to the centerline of the track and originates at 
the locomotive geometric center.
    (b) No carrier subject to this regulation shall operate any 
locomotive to which this regulation is applicable, and of which 
manufacture is completed after December 31, 1979, which produces A-
weighted sound levels in excess of 87 dB at any throttle setting except 
idle, when operated singly and when connected to a load cell, or in 
excess of 70 dB at idle when operated singly, and when measured in 
accordance with the criteria specified in Subpart C of this part with 
slow meter response at a point 30 meters (100 feet) from the geometric 
center of the locomotive along a line that is both perpendicular to the 
centerline of the track and originates at the locomotive geometric 
center.
    (c) Commencing January 15, 1984, no carrier subject to this 
regulation may operate any switcher locomotive 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 
87 dB at any throttle setting except idle, when operated singly and when 
connected to a load cell, or in excess of 70 dB at idle, and when 
measured in accordance with the criteria specified in Subpart C of this 
part with slow meter response at a point 30 meters (100 feet) from the 
geometric center of the locomotive along a line that is both 
perpendicular to the centerline of the track and originates at the 
locomotive geometric center. 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 wtih Subpart C of this 
regulation.
