Berkeley Hills Tunnel
The Berkeley Hills Tunnel is a tunnel which carries Bay Area Rapid Transit (BART) through the Berkeley Hills between Rockridge station and Orinda station. Design While the tracks run in the median of California State Route 24 on both sides of the tunnel, the Berkeley Hills Tunnel allows the tracks to take a straighter alignment offset to the north of the Caldecott Tunnel. The tunnel bores through the Berkeley Hills east of Berkeley and Oakland a distance of through a variety of rock strata, most of which are soft and porous. The earthquake-active Hayward Fault bisects the tunnel about inside the west portal (Oakland side). There are 2 bores, each in diameter, spaced apart. Pedestrian cross-tunnels are spaced every for emergency evacuation in case of fire, etc. There is a ventilation structure at the east portal with roll-down doors that can close off the tunnel end to allow air to be sucked out or blown in. By 2017, cumulative minor damage from fault creep had significantl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tunnel
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railroad Tunnels In California
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antioch–SFO+Millbrae Line
The Antioch–SFO + Millbrae line is a Bay Area Rapid Transit (BART) line in the San Francisco Bay Area that runs from Antioch station to San Francisco International Airport station (SFO), with some trains originating and terminating at Millbrae station. The line is colored yellow on maps, and BART sometimes calls it the Yellow Line. It serves 28 stations in Antioch, Pittsburg, Bay Point, Concord, Pleasant Hill, Walnut Creek, Lafayette, Orinda, Oakland, San Francisco, Daly City, Colma, South San Francisco, San Bruno, and Millbrae. It is the most-used BART line, and the only line with short turn trains to provide additional service. The line is split into two segments. The majority of the line uses the same electric multiple unit trains as the rest of BART, and shares tracks with the four other mainline services. The section from Antioch to near Pittsburg/Bay Point station, known as eBART, uses diesel multiple units. A cross-platform transfer between the two modes is made ...

Smoke Inhalation
Smoke inhalation is the breathing in of harmful fumes (produced as by-products of combusting substances) through the respiratory tract. This can cause smoke inhalation injury (subtype of acute inhalation injury) which is damage to the respiratory tract caused by chemical and/or heat exposure as well as possible systemic toxicity after smoke inhalation. Smoke inhalation can occur from fires of various sources such as residential, vehicle, and wildfires. Morbidity and mortality rates in fire victims with burns are increased in those with smoke inhalation injury. Victims of smoke inhalation injury can present with cough, difficulty breathing, low oxygen saturation, smoke debris and/or burns on the face. Smoke inhalation injury can affect the upper respiratory tract (above the larynx), usually due to heat exposure, or the lower respiratory tract (below the larynx), usually due to exposure to toxic fumes. Initial treatment includes taking the victim away from the fire and smoke, give 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Of Oakland
The Port of Oakland is a major container ship facility located in Oakland, California, in the San Francisco Bay. It was the first major port on the Pacific Coast of the United States to build terminals for container ships. As of 2011 it was the fifth busiest container port in the United States, behind Long Beach, Los Angeles, Newark, and Savannah. Development of an intermodal container handling system in 2002 after over a decade of planning and construction positions the Port of Oakland for further expansion of the West Coast freight market share. In 2019 it ranked 8th in the United States in the category of containers. Early history In 1852, the year of Oakland's incorporation as a town by the California State Legislature, large shipping wharves were constructed along the Oakland Estuary, which was dredged to create a viable shipping channel. 22 years later, in 1874, the previously dredged shipping channel was deepened to make Oakland a deep water port. In the late 19th cent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caldecott Tunnel
