SunLine Transit Agency
SunLine Transit Agency, a transit operator in Riverside County, California (with over 3.5 million passengers a year), is a transit agency providing bus service in the Coachella Valley area and Riverside–Downtown Area during Peak Hours Only. History and description. SunLine Transit Agency (STA) was established under a Joint Powers Agreement, initially between Riverside County and Coachella Valley cities (Coachella, Desert Hot Springs, Indio, Palm Desert, and Palm Springs) on July 1, 1977. Cathedral City, Indian Wells, La Quinta, and Rancho Mirage were added later. Each of the nine member cities selects one member of the SunLine  Board of Directors, with the tenth provided by Riverside County. The service area covers , bounded approximately by the San Gorgonio Pass on the west and the Salton Sea on the southeast. In addition to its transit operations, SunLine regulates local taxi services (as the SunLine Regulatory Administration, a division of the SunLine Services Group) and sells CNG and hydrogen to the public from dispensers at its Thousand Palms and Indio operations facilities, under the brand SunFuels. Routes. STA classified its routes as either trunk or local. The three trunk routes (14, 30, 111) connected major communities, while local routes (15 , 20, 21, 24, 32, 54, 70, 80, 81, 90, 91, and 95) circulated within local communities and served to feed trunk routes. In addition, STA operates paratransit services, branded SunDial. Destinations. Destinations served include: Fares. Up to three kids under 5 ride for free with fare-paying rider. Facilities and fleet. The initial fleet included 22 buses in 1977. SunDial paratransit operations started in 1991. The SunLine Board of Directors adopted a resolution in 1992 to convert their fleet to alternative fuel, and became the first transit agency in the United States to do so in 1994, using compressed natural  gas (CNG) buses. Starting in 2000, SunLine began limited operations with hydrogen fuel cell buses, installing a hydrogen fuel station using a Stuart Energy electrolyzer to supply the XCELLSiS ZEbus for a 13-month trial. The first revenue operations were conducted with the Thor/ISE ThunderPower fuel cell bus, using an ElDorado National EZ-Rider II chassis, between November 2002 to February 2003. By that time, SunLine also had installed a HyRadix methane reformer to generate hydrogen. SunLine tested a hydrogen hybrid internal combustion engine (HHICE) bus in early 2005; the bus was subsequently sent to Winnipeg Transit for cold  weather testing. STA plans to convert their fleet to zero-emission buses (ZEB) by 2035, with only ZEBs purchased starting in 2021. Due to the relatively long fixed routes, the final mix of ZEBs is expected to be mostly hydrogen fuel-cell buses. SunLine has two operations and maintenance facilities: one (including the administrative offices) in Thousand Palms, and another in Indio. , on-site refueling and charging capabilities include an electrolyzer that can produce of hydrogen at Thousand Palms, which came online in 2019, and six 80 kW AC/DC battery-electric bus chargers, three each at both Thousand Palms  and Indio. Hydrogen dispensers (using delivered liquid ) and additional chargers are planned for both facilities. Hydrogen production started in November 2000. Two electrolyzers and a natural gas reformer were part of the initial installation. One electrolyzer, supplied by Teledyne Brown, generated per hour using 7.5 kW of electricity, supplied by solar panels; the other electrolyzer, supplied by Stuart Energy, produced per hour. The reformer produced per hour. The HyRadix Adéo reformer was installed at the end of 2003.
