EMD SD40-2
The EMD SD40-2 is a C-C diesel-electric locomotive built by EMD from 1972 to 1989. The SD40-2 was introduced in January 1972 as part of EMD's '' Dash 2'' series, competing against the GE U30C and the ALCO Century 630. Although higher-horsepower locomotives were available, including EMD's own SD45-2, the reliability and versatility of the SD40-2 made it one of the best-selling models in EMD's history, edged only by the GP9, and the standard of the industry for several decades after its introduction. The SD40-2 was an improvement over the SD40, with modular electronic control systems similar to those of the experimental DDA40X. Peak production of the SD40-2 was in the mid-1970s. Sales of the SD40-2 began to diminish after 1981 due to the oil crisis, increased competition from GE's Dash-7 series and the introduction of the EMD SD50, which was available concurrently to late SD40-2 production. The last SD40-2 delivered to a United States railroad was built in July 1984, wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD GP38-2
The EMD GP38-2 is an American four-axle diesel-electric locomotive built by General Motors, Electro-Motive Division. Part of the EMD Dash 2 line, the GP38-2 was an upgraded version of the earlier GP38. Power is provided by an EMD 645E 16-cylinder engine, which generates 2,000 horsepower (1.5 MW). GP38-2W The GP38-2W is a Canadian variant of the GP38-2. It is easily distinguished by its wide-nose Canadian comfort cab. 51 of these locomotives were produced for the Canadian National Railway during 1973–1974. Although a W is commonly suffixed to the name, it is actually an addition by enthusiasts to help specify the presence of a CN-spec comfort cab. No locomotives built using CN's design of comfort cab ever featured a W in their designation, as the presence of the cab did not mechanically alter the locomotive. This is reflected by the lack of the "W" in the model designation on the builders' plates of these units. There are snow shields above the inertial-filter centra ...

EMD GP40-2
The EMD GP40-2 is a 4-axle diesel locomotive built by General Motors Electro-Motive Division as part of its Dash 2 line between April 1972 and December 1986. The locomotive's power is provided by an EMD 645E3 16-cylinder engine which generates . Production Standard GP40-2 production totaled 861 units, with 817 built for U.S. railroads, and 44 for Mexican railroads. In addition, three GP40P-2s, passenger versions of the GP40-2, were built in 1974 and 279 were built by General Motors Diesel (GMD) between 1974 and 1976. Total production of the GP40-2 and its variations totaled 1,143 units. Performance With the 62:15 gearing (65-70 mph maximum) EMD rated the GP40-2 at 55,400 lb continuous tractive effort. Some had PF21 module that reduced the output below 23 mph, lowering continuous speed down to 11 mph.

Grumman AF Guardian
The Grumman AF Guardian was the first purpose-built anti-submarine warfare (ASW) carrier-based aircraft to enter service with the United States Navy.Kowalski 1991, p. 3. It consisted of two airframe variants, one for detection gear, the other for weapons. The Guardian remained in service until August 1955, when it was replaced by the twin-engined Grumman S-2 Tracker. The Guardian was the largest single-engine piston-powered carrier aircraft ever to see service. Design and development The original design concept for the aircraft that would become the Guardian, the XTB2F of 1944, was for a twin-engined aircraft with a warload and a range of 3,700 mi (5,950 km).Kowalski 1991, pp. 2–3. This was considered to be too large for practical use from an , and was cancelled in 1945, replaced by a modified Grumman F7F Tigercat, the XTSF-1. However, this too was considered impractical, and another alternative, the internally developed Grumman Model G-70, was selected instead, ...

Vandenberg AFB Space Launch Complex 2
Space Launch Complex 2 (SLC-2) is an active rocket launch site at Vandenberg Space Force Base, in California, USA. It consists of two launch pads. The East pad (SLC-2E, originally LC 75-1-1) was used for Delta, Thor-Agena and Thorad launches between 1966 and 1972 and has been demolished. The West pad (SLC-2W, originally LC 75-1-2) was used for Delta, Thor-Agena and Delta II launches from 1966 until 2018, when the Delta II performed its last flight. SLC-2W has been repurposed to launch Firefly Alpha for Firefly Aerospace and on October 15, 2020 the Delta II mobile service tower suffered a fire during demolition. The maiden flight of Firefly Alpha took place on September 3, 2021 and resulted in a flight failure. The second flight on 1 October 2022 was successful in reaching orbit. Space Launch Complex 2 was originally part of Launch Complex 75 (LC 75) and was known by designation LC 75-1 or just 75-1 (and the launch pads were designated LC 75-1-1 and LC 75-1-2).

BBC 2W
BBC 2W was a digital television channel run by the BBC in Wales until January 2009. It replaced the standard BBC Two broadcast on digital services in Wales — running on weekdays from 8.30pm to 10pm. Launched on 5 November 2001, it had an initial reach of 1.1 million viewers. History It served as a replacement for BBC Choice Wales, which had been shut down on 30 March 2001. 2W broadcast in English and was aimed at the English-speaking population, unlike S4C, which broadcasts primarily in Welsh. The digital-only service was replaced with a single BBC Two for Wales on 2 January 2009. BBC 2W was designed to offer "a unique experience unavailable anywhere else with the watchwords of topicality and style, intelligence with an occasional touch of irreverence, shining through" for Welsh audiences. The channel name on the Electronic Programme Guide was BBC 2W although outside its broadcast hours the channel was referred to onscreen as ''BBC Two Wales'', using the BBC Two logo. The ...

Telecommunications Circuit
A telecommunication circuit is a path in a telecommunications network used to transmit information. Circuits have evolved over time from generally being built on physical connections between individual hardware cables, as in an analog phone switch, to virtual circuits established over packet switching networks. Definitions A telecommunication circuit may be defined as follows: * The complete path between two terminals over which one-way or two-way communications may be provided. * An electronic path between two or more points, capable of providing a single or multiple communication channels. * An electronic closed-loop path among two or more points used for signal transfer. In operational terms, a telecommunication circuit may be capable of transmitting information in only one direction (''simplex'' circuit), or it may be bi-directional (''duplex'' circuit). Bi-directional circuits may support half- duplex operation, when only one end of the channel transmits at any one tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhoon Isa (1997)
Typhoon Isa was the first of a record eleven super typhoons to occur during the 1997 Pacific typhoon season. The second tropical cyclone of the season, Isa developed from a disturbance in the monsoon trough near the Caroline Islands on April 12. It moved erratically at first, though after attaining tropical storm status it curved westward due to the subtropical ridge to its north. Isa very gradually intensified, and on April 20 the typhoon reached peak 1-min winds of 270 km/h (165 mph), as reported by the Joint Typhoon Warning Center; Japan Meteorological Agency reported maximum 10-min winds of 155 km/h (100 mph). After turning northward, it accelerated to the northeast, and merged with a larger extratropical cyclone on April 24. Early in its duration, Isa caused light rainfall and moderate winds on Pohnpei. Later, a stationary rainband from the typhoon dropped heavy precipitation on Guam during its dry season. Damage in the Guam National Weather Service area ...
