0(c E1)r_ MEMORANDUM <br /> C.) Al�— O <br /> OREGOv‘ <br /> TO: Transportation Advisory Board <br /> FROM: William R. Farley, PE—Traffic Engineer <br /> Engineering Department <br /> SUBJECT: Railroad Quiet Zones <br /> DATE: November 13, 2020 <br /> Summary <br /> Multiple requests have been received to initiate the establishment of quiet zones on the <br /> Portland and Western Railroad line through the City of Lake Oswego. To receive authorization <br /> for quiet zones,jurisdictions are required to work with the railroad that owns the track and the <br /> Federal Railroad Administration to mitigate additional risk that may result from allowing trains <br /> to abstain from the routine horn sounding. This report will go into the details of the <br /> requirements, and what it would cost the City to make improvements to meet those <br /> requirements. <br /> Rules & Regulations <br /> Federal regulations require that trains sound their horns no more than one-quarter of a mile in <br /> advance of and between 15 and 20 seconds prior to entering public highway-rail grade <br /> crossings as a universal safety precaution. While an active quiet zone will allow trains to <br /> discontinue the regular sounding their horn, trains will still be able to use horns in emergency <br /> situations or to comply with other railroad or Federal Railroad Administration (FRA) rules. Quiet <br /> zones also do not eliminate the use of locomotive bells at crossings. <br /> New quiet zones requested by a public authority must be at least one-half mile in length and <br /> contain at least one public grade crossing. Every public grade crossing in a quiet zone must be <br /> equipped at a minimum with active grade crossing warning devices consisting of flashing lights, <br /> gates, constant warning time devices, and power out indicators. Since the absence of routine <br /> horn sounding increases the risk of collisions at grade crossings, the public authority is usually <br /> required to mitigate any additional risk by funding and installing Supplementary Safety <br /> Measures. <br /> 503.675.3984 380 A Avenue PO BOX 369 Lake Oswego, OR 97034 <br />
