Magnetic Signal Company
The Magnetic Signal Company was an American company based in Los Angeles, California focused on railway signalling. The company was the manufacturer of the ubiquitous "Magnetic Flagman" wigwag railroad crossing (or level crossing) signal seen all over California and the western states. History The company was established sometime after 1910, and received its first patent, on May 19, 1914. Its general offices and factory were located at 3355 East Slauson Avenue in Vernon, an industrial area just south of downtown Los Angeles. This was an ideal location for a company that would eventually supply over 7,000 wig-wag signals to the country and the world, as it had great rail access for not only shipping its products out, but for bringing in the raw materials needed to manufacture its products. The Union Pacific's old Los Angeles and Salt Lake line to the harbor ran just east of that location, and the main lines of the Southern Pacific and Santa Fe ran by just north of there as well. ...

Orange Empire Railway Museum
The Southern California Railway Museum (SCRM, reporting mark OERX), formerly known as the Orange Empire Railway Museum, is a railroad museum in Perris, California, United States. It was founded in 1956 at Griffith Park in Los Angeles before moving to the former Pinacate Station as the "Orange Empire Trolley Museum" in 1958. It was renamed "Orange Empire Railway Museum" in 1975 after merging with a museum then known as the California Southern Railroad Museum, and adopted its current name in 2019. The museum also operates a heritage railroad on the museum grounds. Background The collection focuses on Southern California's railroad history. It houses the largest collection of Pacific Electric Railway rolling stock in the world, much of it rescued from scrapyards after the discontinuation of their passenger operations in 1961. Two early Los Angeles narrow gauge streetcars from the Los Angeles Railway or standard gauge streetcars from the Pacific Electric Railway run each weekend o ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pacific Electric Railway
The Pacific Electric Railway Company, nicknamed the Red Cars, was a privately owned mass transit system in Southern California consisting of electrically powered streetcars, interurban cars, and buses and was the largest electric railway system in the world in the 1920s.

Santa Fe Railroad
The Atchison, Topeka and Santa Fe Railway , often referred to as the Santa Fe or AT&SF, was one of the larger railroads in the United States. The railroad was chartered in February 1859 to serve the cities of Atchison and Topeka, Kansas, and Santa Fe, New Mexico. The railroad reached the Kansas–Colorado border in 1873 and Pueblo, Colorado, in 1876. To create a demand for its services, the railroad set up real estate offices and sold farmland from the land grants that it was awarded by Congress. Despite being chartered to serve the city, the railroad chose to bypass Santa Fe, due to the engineering challenges of the mountainous terrain. Eventually a branch line from Lamy, New Mexico, brought the Santa Fe railroad to its namesake city. The Santa Fe was a pioneer in intermodal freight transport; at various times, it operated an airline, the short-lived Santa Fe Skyway, and the fleet of Santa Fe Railroad Tugboats. Its bus line extended passenger transportation to areas not acce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Pacific Transportation Company
The Southern Pacific (or Espee from the railroad initials- SP) was an American Class I railroad network that existed from 1865 to 1996 and operated largely in the Western United States.

Electronics Industry
The electronics industry is the economic sector that produces electronic devices. It emerged in the 20th century and is today one of the largest global industries. Contemporary society uses a vast array of electronic devices built-in automated or semi-automated factories operated by the industry. Products are primarily assembled from metal-oxide-semiconductor (MOS) transistors and integrated circuits, the latter principally by photolithography and often on printed circuit boards. The industry's size, the use of toxic materials, and the difficulty of recycling have led to a series of problems with electronic waste. International regulation and environmental legislation have been developed to address the issues. The electronics industry consists of various sectors. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over as of 2018. The largest industry sector is e-commerce, which generated over in 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
