Caltrain Centralized Equipment Maintenance and Operations Facility
San Jose, CA
The Caltrain Centralized Equipment Maintenance and Operations Facility (CEMOF) is busy with train inspections, maintenance, repairs, and train washing. This 20-acre facility also houses storage tracks and the central control facility for directing and monitoring train traffic between Gilroy and San Francisco. As directed by Caltrain, we conducted long-term noise monitoring at locations around the facility to determine the noise levels of train passbys and to determine which trains and/or tracks generated wheel squeaks. Next we analyzed the wheel squeak frequency spectrum to determine the optimum track treatment to mitigate the squeaks.
