CALTRAIN EXTENSION TO MONTEREY COUNTYALTERNATIVES ANALYSISSalinas Layover FacilityAn overnight storage and light maintenance facility will be required to accommodate the Caltrainextension to Salinas. UPRR has determined that their existing, adjacent yard will not be available tomeet this requirement. In general, the Salinas layover facility will include the following elements:• Construction of yard track and turnouts to initially accommodate up to four Caltrain consists• Construction of maintenance roads• Perimeter fencing and security lighting• Drip pans for the fueling positions and spill containment• Standby power and potable water pedestals• A small building for housing brake shoes, tools, and supplies• A crew base building.Storage for up to four train sets is envisioned for the Caltrain Extension Alternative, similar to theexisting Caltrain layover facility at Gilroy. The conceptual plan illustrated as Figure 3-6 will allow forthe expansion of this facility to accommodate up to six Caltrain consists. The estimated capital cost ofthis yard is $11.7 million expressed in FY 2007 dollars, and $12.3 million expressed in year ofexpenditure dollars.Gilroy Yard ImprovementsExtension of Caltrain service south of Gilroy will require a new track connection at the south end ofthe station track to permit passenger train flow-through while maintaining passenger boarding fromthe existing station platform. The track extension will include demolition, track, ties, ballast, one newturnout, modifying railroad signal interlocking, and modifying motorist warning devices at 10th Street,immediately adjacent to the Gilroy station and at Luchessa Street. Figure 3-7 provides a conceptualplan that shows the improvements needed at Gilroy. These improvements are estimated to cost $4.1million expressed in FY 2007 dollars and $4.4 million expressed in year of expenditure dollars.UPRR Coast Main Line ImprovementsThe Caltrain Extension Alternative will include railway improvements to the existing UPRR Coastmain line, passing tracks, yard tracks, and branch line connections to allow Caltrain to extend servicefrom Gilroy in Santa Clara County, through San Benito County to Salinas in Monterey County. Allrailway improvements noted below will occur within the UPRR right-of-way. Milepost (MP) locationsare approximate.Gilroy• Install new second main track from 10th Street to East Luchessa Avenue (MP 77.65 toMP 78.52)• Tenth Street (MP 77.70).
