CHAPTER 2: PROJECT DESCRIPTION CHAPTER 2: PROJECT DESCRIPTION The proposed project is the electrification of the entire Caltrain line from the current northern terminus at Fourth and King streets in the City of San Francisco to the southern terminus at the Gilroy station in downtown Gilroy, a distance of approximately 80 miles. The project location is shown in Figure 2-1; a project vicinity map showing each of the stations on the line is provided in Figure 1.2-1. 2.1 LOCATION AND LIMITS The Peninsula Joint Powers Board (JPB) owns and operates approximately 50 miles of primarily two-track mainline railroad right-of-way between the Fourth and King Station in San Francisco and the Tamien Station just south of San Jose in Santa Clara County. JPB purchased this right-of-way from the Southern Pacific Transportation Company in 1992. Between Tamien Station and the Gilroy Station in downtown Gilroy, the mainly single-track right-of-way is owned by the Union Pacific Railroad (UPRR). Caltrain has trackage rights under agreement with the UPRR to provide commuter service in this approximately 30-mile segment of UPRR’s right-of-way. Caltrain trains consist of diesel-hauled, bi-level “gallery” cars and currently provide approximately 15- to 30-minute peak period service in both northbound and southbound directions between San Jose and San Francisco, and 30-minute service during the middle of the day. A total of 76 daily trains currently operate over the JPB-owned, northern portion of the route between San Jose and San Francisco. Caltrain adjusted its peak-hour service and reduced the number of trains from 80 daily trains in August 2002 in response to declining ridership and a tightly constrained budget, due to declining Bay Area economic conditions beginning in 2001 and continuing through this writing. Included in the current 76-train total, Caltrain presently operates four trains for the northbound morning commute, and four trains for the southbound evening commute over the southern portion owned by UPRR and operated by Caltrain through a “commuter rail Trackage Rights Agreement.” These trains travel northward from Gilroy to San Francisco at roughly 30-minute intervals between 5:18 and 7:01 a.m. and southward from San Francisco to Gilroy at roughly 50-minute intervals between 3:07 and 5:25 p.m. In addition, between Santa Clara and San Francisco, UPRR operates approximately six daily freight trains through a “freight Trackage Rights Agreement” with Caltrain. From Santa Clara to San Jose, on a joint use corridor, UPRR operates approximately 12 to 20 daily freight trains. Passenger trains also operate in the joint use corridor from Santa Clara to San Jose, including the Capitol Corridor (12 daily trains), the Altamont Commuter Express (six daily trains) and the Amtrak Inter-city (two daily trains). Caltrain Electrification Program EA/EIR 2-1 SAN FRANCISCO San Mateo County PROJECT LOCATION Alameda County Santa Cruz County SAN JOSE Santa Clara County GILROY Figure 2-1 PROJECT LOCATION CALTRAIN ELECTRIFICATION PROGRAM CHAPTER 2: PROJECT DESCRIPTION Substantial service increases to 98 daily trains in the San Francisco to San Jose segment and eight daily trains in the San Jose to Gilroy segment are planned to be implemented within the next six years, and daily operations of 132 trains in the San Francisco to San Jose segment and 20 daily trains in the San Jose to Gilroy segment are planned by 2020. Additional track, signal, station and terminal capacity improvements will be necessary to provide for the increased levels of service. These facilities are not included in the scope of the environmental review within the present document. They are being addressed in separate environmental documents in accordance with the requirements of applicable environmental regulations and guidance and as such, are included within the No-Project Alternative in this environmental document. The facilities included in the Electrification Program Alternative will be designed and located to take into consideration future track, signal, station, bridge and other improvements and to preclude or minimize to the extent possible future modification or relocation of constructed electrification facilities. Modifications and relocations of constructed electrification facilities are, however, very likely to occur, given the extent of programmed changes to the infrastructure within Caltrain’s rail corridor over the next 20 years. 2.2 BACKGROUND In 1999, the JPB adopted the Caltrain Rapid Rail Plan. This plan envisioned a program of facility rehabilitation and enhancement and systemwide electrification improvements to enable increased frequency, capacity and reliability of Caltrain service and to reduce travel times. The Rapid Rail Plan also called for completion of the environmental studies to extend Caltrain from its current San Francisco terminus at Fourth and King streets into downtown San Francisco. A Draft Environmental Impact Statement/Environmental Impact Report (Draft EIS/EIR) for the Caltrain Downtown Extension, including electrification of the line from downtown San Francisco to Gilroy, was circulated for public review and comment in March of 1997, but the Final EIS/EIR was never completed. This project reinitiated environmental studies in February 2001, and an EIS/EIR for the Transbay Terminal/Caltrain Downtown Extension/Redevelopment Area is being prepared by the Federal Transit Administration (FTA), JPB, the City and County of San Francisco, and the San Francisco Redevelopment Agency (see Section 1.3, Related Projects). Many of the other facility rehabilitation and enhancement improvements envisioned in the Rapid Rail Plan are already in place or underway, and they are included here in the No-Project Alternative. The present environmental document focuses on the facilities and improvements required to achieve electrification of the entire Caltrain line from the San Francisco Fourth and King Station to the Gilroy Station in downtown Gilroy. Electrification of the portion of the line from Fourth and King streets northward into downtown San Francisco is being addressed in the environmental document for the Transbay Terminal/Caltrain Downtown Extension/ Redevelopment Area project. Previous studies include the October 1992 Feasibility Study: Electrifying the Caltrain/PCS Railroad; the March 1997 Draft Environmental Impact Statement/Draft Caltrain Electrification Program EA/EIR 2-3 CHAPTER 2: PROJECT DESCRIPTION Environmental Impact Report for the Caltrain Downtown San Francisco Extension; and the October 1998 Caltrain Rapid Rail Study. 2.3 ALTERNATIVES A range of different propulsion options was considered to meet the project purpose and need. Four alternatives were ultimately withdrawn from further consideration based on low cost- effectiveness, environmental effects, potential project delays, or other factors. These alternatives and the reasons why they were withdrawn are presented in Section 2.4, Alternatives Considered and Withdrawn. Alternatives evaluated in this EA/EIR consist of a No-Electrification (or No-Project) Alternative and the Electrification Program Alternative. The Electrification Program Alternative includes alternative rolling stock types. 2.3.1 THE NO-ELECTRIFICATION (NO-PROJECT) ALTERNATIVE The No-Electrification Alternative constitutes the No-Project Alternative for the purposes of the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA). The No-Electrification (or No-Project) Alternative incorporates a series of rehabilitation improvements, enhancements and additions to the existing system, not including electrification, that would provide an improved level of service. These improvements will generally be carried out within the existing JPB or UPRR owned railroad rights-of-way and environmental and other issues will be addressed separately in accordance with applicable environmental requirements. The No-Electrification Alternative assumes that the following Caltrain facilities will exist at the completion of the Caltrain Express (CTX) project (formerly known as the “Bonanza” and “Baby Bullet” projects), consistent with the Rapid Rail Program adopted by the JPB in 1999: • Rehabilitation of the Existing System – long-term repairs, reconstruction and modernization of the existing tracks, signals, bridges, stations, rolling stock and other systems. • Enhancements and Capacity Improvements – additions and betterments to the rail system including additional main and passing tracks to facilitate train meets and passes; enhanced signal and communications systems (centralized train control [CTC] that can accommodate an up-grade to automatic train control [ATC], and fiber optics); modernized stations; a new centralized equipment maintenance and operations facility (CEMOF) comprising shop, buildings and support facilities at the Lenzen site in San Jose; vehicular and pedestrian grade separations; and additional rolling stock. Also included in this category are grade crossing and station closures and consolidations. • New CTX service consisting of 10 express trains per day with projected 57-minute travel times between San Francisco and San Jose by early 2004. • A variety of passenger station improvements to permit simpler ticketing arrangements and create improved station amenities. 2-4 Caltrain Electrification Program EA/EIR CHAPTER 2: PROJECT DESCRIPTION Additional proposed increases in Caltrain's service level to provide 98 daily trains in the San Francisco to San Jose segment (including eight daily trains in the
