Background
Caltrain, in cooperation with the City of San Mateo, will raise the tracks and slightly lower the road (grade separate) at E. 25th Avenue in San Mateo. This will improve safety for both motorists and pedestrians, and it will reduce local traffic congestion in San Mateo. In addition, the project will create new east-west street connections at 28th and 31st Avenues; and as part of the project improvements, Caltrain will build a new elevated Hillsdale Station with updated amenities between E. 28th and E. 31st Avenues.
In order to maintain regular train service, some activities will be conducted during nights and weekends, outside of normal train service hours. Neighbors may experience construction noise and light during these times. The overall project construction is expected to be complete in fall 2021.
How to Stay Informed
For more information on the 25th Avenue Grade Separation Project, please visit www.Caltrain.com/25thgs. For questions about the project, please call the Caltrain Customer Service at 1.800.660.4287 or email SMgradesep@Caltrain.com.
Caltrain Electrification
Caltrain Electrification is a key component of the Caltrain Modernization program which will electrify the Caltrain Corridor from San Francisco's 4th and King Caltrain Station to approximately the Tamien Caltrain Station.
The primary purpose of Caltrain Electrification is to improve Caltrain system performance, reduce long-term environmental impact by reducing noise, improving regional air quality and reducing greenhouse gas emissions. An electrified Caltrain system would better address Peninsula commuters' vision of increased service and improved travel times in an environmentally friendly and reliable way. This also is expected to help accommodate increase system ridership through improved system operations.
For information on upcoming community construction update meetings, please visit the Caltrain Electrification Project events page at www.CalMod.org/Events.

Caltrain Grade Crossing Improvements Project in San Mateo and Menlo Park
Caltrain, in cooperation with our city partners, are working to improve the safety at 5 at-grade crossings (intersections where train tracks cross a street) in San Mateo and Menlo Park. These improvements will increase the safety for vehicles, pedestrians and cyclists. Improvements include more clearly-marked pedestrian crossings with new paint striping and lettering, and pavement markers. The improvement plan also calls for the installation of a fixed median with flexible bollards. The median is designed to prevent motorists from driving around lowered crossing gates.
Menlo Park Update
Work to relocate the median at the intersection of Glenwood Avenue and Garwood Way in Menlo Park has been completed. We are now working with the city to approve the final median placement. We appreciate the community's patience and cooperation as we've worked to improve the safety of this crossing.
