Sec. 201.16  Standard for locomotive load cell test stands.

    (a) Effective January 15, 1984, no carrier subject to this reguation 
shall operate locomotive load cell test stands that exceed an A-weighted 
sound level of 78 dB when measured with slow meter response in 
accordance with Subpart C of this part excluding Sec. 201.23 (b) and 
(c), at a point 30 meters (100 feet) from the geometric center of the 
locomotive undergoing test, along a line that is both perpendicular to 
the centerline of the track and originates at the locomotive geometric 
center, and in the direction most nearly towards the closest receiving 
property measurement location. All locomotive load cell test stands in a 
particular railroad facility are in compliance with this standard if the 
A-weighted sound level from the load cell does not exceed 65 dB at any 
receiving property measurement location near that particular railyard 
facility and when measured with fast meter response in accordance with 
Subpart C of this regulation.
    (b) If the conditions of any part of Sec. 201.23(a) cannot be met at 
a specific load cell test stand site, then the A-weighted sound level 
from that specific load cell test stand must not exceed 65 dB when 
measured with fast meter response at a receiving property measurement 
location more than 120 meters (400 feet) from the geometric center of 
the locomotive being tested and in accordance with Subpart C of this 
regulation.
