5.4 Stationary Horns Wayside or stationary horns are a relatively new technology that has recently been approved for general installation. The wayside horn replaces the train mounted horn with a horn mounted at the crossing. The wayside horn is activated by the crossing signal system. The Road Authority is generally responsible for installation and maintenance of the system. The noise level is comparable to a train horn, but it decreases the noise impact area. The stationary horn works well in non-residential areas because the immediate area near the crossing is subjected to the full noise of the horn for 25 seconds, rather than a gradual increase as the train approaches. The wayside horn was authorized in the quiet zone regulations, but it is technically not in a quiet zone. It is considered the same risk level as a train mounted horn. Stationary horn costs range from $100,000 to $150,000, plus a monthly maintenance cost. 6.0 CROSSING ANALYSIS AND ALTERNATIVES There are 12 at grade crossings within the City. The FRA rules require that a multiple crossing quiet zone must be on same corridor and have similar characteristics to be combined into a quiet zone. The following is a detailed look at the improvements needed for each crossing. Assuming the warning devices had signal with gates and CWT, a risk index under 13,811 allows for a quiet zone without any other improvements. 6.1 North-South Rail Line 1. Terminal Road (DOT#463568P) Terminal Road in an east -west roadway in an industrial area of southwest Roseville. The roadway is 4 lanes. The warning devices consist of cantilever flashing light signals with DC circuitry. The risk index is 10,862. Improvements needed would be a conversion to gates and center medians. This could be a standalone zone or combined with the County Road C crossing. Cost range is $125,000 to $200,000. 2. County Road C (DOT #4635621) County Road C is a Ramsey County roadway that is currently being rebuilt. The new roadway section will be five lane divided section. The land use is primarily industrial. The warning devices were upgraded in2019 to cantilever signals and gates with CWT. The risk index is 21,930. Minor median work may be needed to bring the crossing into SSM compliance. 3. County Road C2 ( DOT #463563F) The County Road C2 crossing is under the City of Roseville. It is a 3 -lane roadway with short medians on each approach. The warning devices are cantilever signals with gates installed in 2019 with an island circuitry. The
