Abstract:This handbook is an update, restructuring and expansion of the 1982 document “Handbook for the Measurement,
Analysis, and Abatement of Railroad Noise” originally developed by Wyle Laboratories.
The handbook is intended as guidance for those conducting sound level measurements for railroad regulatory
compliance under 40CFR Part 201 and 49CFR Parts 210, 222, 227, 228, and 229. Specifically, it addresses 1)
noise generated by locomotives and rail-cars during line haul operations, 2) noise generated by yard
operations from stationary locomotives, locomotive switching, car-coupling impacts, retarders, and load cell
test stands, 3) locomotive horn sound levels, 4) noise levels inside locomotive cabs, 5) noise levels
inside employee sleeping quarters, and 6) train employee occupational noise exposure. It contains a history
of these regulations, a general procedure for conducting a noise measurement or noise exposure monitoring
program and regulation-specific measurement and data analysis procedures and guidance for each type of
compliance, including planning recommendations and measurement equipment. It also contains example forms
and log sheets to help facilitate the documentation of each measurement. These general procedures can be
easily adapted to effectively measure most types of railroad-generated noise.
