Tualatin Quiet Zone

January 11, 2011, train operations in residential areas in the Tualatin area got a lot quieter. RSS/MJG and GE Transportation Systems worked with TriMet and their stakeholders to design, furnish and install/commission crossing improvements within the Washington County Commuter Rail (WCCR) corridor. Tualatin, OR has residential areas along WCCR’s Westside Express Service (WES) tracks. Cross streets in these areas had railroad crossings where sounding of locomotive horns was required by the Federal Railroad Authority. The train horn noise was the source of many complaints from residents in the Tualatin area. By implementation of a quiet zone, the quality of life for the community has improved. The RSS/MJG team completed commissioning the train horn noise reduction system ahead of schedule in mid-December, 2010.

During construction, the RSS/MJG team maintained the existing signal system for on-going Portland & Western Railroad and TriMet WES operations in the area. RSS was responsible for this design-build effort which included seven public railroad crossings. Four crossings required the installation of automated wayside horns which is a simulated train horn localized at the crossing. The three other crossings required installation of four-quadrant gates with an exit gate management system including automobile vehicle presence detection.
