California State Rail Plan 2007-08 to 2017-18

Chapter IX – Commuter Rail ServicesCP Carl to CP Farr Double-Track – This project would add two miles of secondtrack and a new concrete bridge to the current alignment between downtownCarlsbad and Cannon Road in Carlsbad, connecting to the double-track at Cannon.The resulting double track segment would be a total of five miles in length.The bridge would be virtually identical to the new concrete bridge at MP 230.6completed by NCTD in 2006. Amtrak has provided much of the funding for thisproject.Solana Beach Station Parking – A 500-space parking structure will beconstructed as part of a mixed-use development located at the Station.Sorrento Valley Station Platform Extension –This project will extend the twoplatforms at Sorrento Valley Station to up to 1,000 feet in length, in order toaccommodate longer trainsets. The current platforms can only accommodate fivecartrains, and ridership growth is such that six-car trains will soon be needed.Unfunded and Under-funded ProjectsSan Dieguito River Bridge Replacement and Second Main Track –This project would replace a single-track bridge with a double-track concretebridge, and add 1.1 miles of second main track to connect the existing passingtracks at Solana Beach and Del Mar. The resultant double-track will be 2.8 milesin length. The bridge has been the target of past marine borer attacks, and is underattack again at this time.San Luis Rey River Bridge and Second Track Project – This project wouldreplace the 700-foot long, 1920’s-era, troubled, single-track steel bridge at theSan Luis Rey River with a new double track concrete bridge, and connect withdouble-track segments to the north and south to create a continuous stretch ofdouble track from CP Westbrook (MP 223.6) through Oceanside Transit Centerand south to CP Escondido Junction (MP 227.2), a total length of 3.6 miles.San Mateo Creek Bridge North Approach – The current 558-foot long timbertrestle north approach to this bridge has been burned repeatedly during the lastthree decades and is in very poor condition. NCTD has expended approximately$500,000 on interim repairs in the past two years but this bridge portion must bereplaced. NCTD has undertaken preliminary design and environmental workusing its existing funding sources but no construction funding has been identifiedto date. Speed restrictions are already in place and more severe speed restrictionswill become necessary if this bridge is not replaced soon. This bridge is used byAmtrak, BNSF, and Metrolink trains, but not by Coaster trains.Replacement of other Single-Track Timber Bridges – There are seven agingtimber trestles in Sorrento Valley, in an alignment distance of only 3.8 miles.These single-track bridges date back to as early as 1911. Replacement anddouble-tracking of this segment of the alignment will require constructing the newbridges in groups to minimize environmental impact. In addition, the timber141
