Feedback from Burlingame
• Study range of alternatives: tunnel, trench and cut & cover
• Study and mitigate impacts to the Community
• Connected small town -- avoid visual and physical barrier
• Residential neighborhoods or businesses
• Downtown Burlingame and Broadway –Future Mixed-Use Housing
• Two Historic Stations and Eucalyptus Grove
• Noise and vibration
• Construction and utilities
• Property impacts and property values
• Caltrain service & restore service to Broadway Station & electrification
• Grade separations, Broadway and Highway 101 interchange
• Millbrae High Speed Train Station
• Traffic, parking, California Avenue, Rollins Road and security
• Coordinated and transparent public process

Planning Assumptions
• Stay within existing Caltrain Right of Way to the extent
feasible
• Four track, grade separated system
• High-speed train up to 125 MPH; Caltrain up to 110 MPH
• Opportunity for joint operations
![Page 5: New Preliminary Alternatives AnalysisRail+Program/PrelimAA... · 2010. 5. 12. · 1. Prelim. Alternatives Analysis -- Spring 2010 2. Stations -- Spring/Summer 2010 3. 15% Engineering](https://reader033.fdocuments.us/reader033/viewer/2022051922/600f82b176cfe32d6a2fbff8/html5/thumbnails/5.jpg)
Planning Assumptions (continued)
• Improve Caltrain Service
• Shared High Speed & Caltrain Stations
• San Francisco, Millbrae (SFO), San Jose
• Potential high-speed train stop:
–Redwood City
–Palo Alto
–Mountain View
![Page 6: New Preliminary Alternatives AnalysisRail+Program/PrelimAA... · 2010. 5. 12. · 1. Prelim. Alternatives Analysis -- Spring 2010 2. Stations -- Spring/Summer 2010 3. 15% Engineering](https://reader033.fdocuments.us/reader033/viewer/2022051922/600f82b176cfe32d6a2fbff8/html5/thumbnails/6.jpg)
Corridor Findings
• Caltrain corridor is preferred alignment
• San Francisco joint terminal solution: Transbay
Transit Center and 4th and King
• Limit use of high berms and retaining walls
• Tunnel options added
• Ending High Speed Train service in San Jose
would negatively impact Caltrain and its riders, and
does not meet Prop. 1A requirements.
