Tektronix 4010

The Tektronix 4010 series was a family of text and graphics computer terminals based on the company's storage tube technology. There were several members of the family introduced through the 1970s, the best known being the 11-inch 4010 and 19-inch 4014. They were widely used in the CAD market in the 1970s and early 1980s.

The 4000 series were much less expensive than earlier graphics terminals, such as the IBM 2250, because no additional electronics were needed to maintain the display on the screen. They remained popular until the introduction of inexpensive graphics workstations in the 1980s. The new graphics workstations used raster displays and dedicated screen buffers that became more affordable as solid state memory chips became cheaper.

History

The Tektronix direct-view storage tube was first used in the Tektronix 564 oscilloscope in 1963, and was first used for non-oscilloscope applications in the 601 monitor in 1968. A number of graphics terminals based on this tube and others from the 600-series were developed, including the Advanced Remote Display Station from MIT's Project MAC, and the KV8I (later, KV8E) from Digital Equipment Corporation using the later 11-inch diagonal 611. These consisted of just the tube and related basic electronics, it was up to software on the host computer to produce a display by driving the controls directly.

Union Pacific Railroad

The Union Pacific Railroad (reporting mark UP) is a Class I line haul freight railroad that operates nearly 8,500 locomotives over 32,000 route-miles in 23 states west of Chicago, Illinois and New Orleans, Louisiana. The Union Pacific Railroad network is the largest in the United States and is serviced by more than 47,000 employees.

Union Pacific Railroad is the principal operating company of Union Pacific Corporation (NYSE: UNP); both are headquartered in Omaha, Nebraska. Over the years Union Pacific Corporation has grown by acquiring other railroads, notably the Missouri Pacific, Chicago & North Western, Western Pacific, Missouri-Kansas-Texas, and the Southern Pacific (including the Denver & Rio Grande Western).

Union Pacific Corporation's main competitor is the BNSF Railway, the nation's second largest freight railroad, which also primarily services the Continental U.S. west of the Mississippi River. Together, the two railroads have a duopoly on all transcontinental freight rail lines in the U.S.

Union Pacific Big Boy

Big Boy is the popular name of the American Locomotive Company 4000-class 4-8-8-4 articulated, coal-fired, steam locomotives manufactured between 1941 and 1944 and operated by the Union Pacific Railroad until 1959.

The Big Boy fleet of twenty five locomotives were used primarily in the Wyoming Division to haul freight over the Wasatch mountains between Green River, Wyoming and Ogden, Utah. They were the only locomotives to use a 4-8-8-4 wheel arrangement consisting of a four-wheel leading truck for stability entering curves, two sets of eight driving wheels and a four-wheel trailing truck to support the large firebox.

According to Union Pacific senior manager of Heritage Operations Ed Dickens Jr., the 4-8-8-4 series originally was to have been called "Wasatch". One day while one of the engines was being built an unknown worker scrawled "Big Boy" in chalk on its front. With that, the legendary name was born and has stuck ever since.

Design

Union Pacific introduced the Challenger-type (4-6-6-4) locomotives in 1936 on its main line over the Wasatch Range between Green River, Wyoming and Ogden, Utah. For most of the route, the maximum grade is 0.82% in either direction, but the climb eastward from Ogden, Utah into the Wasatch Range reached 1.14%. Hauling a 3,600-short-ton (3,300 t; 3,200-long-ton) freight train demanded doubleheading and helper operations, and adding and removing helper engines slowed operations.

Union Pacific 4014

Union Pacific 4014, or UP 4014, is a four-cylinder articulated 4-8-8-4 Big Boy-type steam locomotive owned by Union Pacific Railroad. 4014 was retired from service on July 21, 1959 and donated to the Railway & Locomotive Historical Society in Pomona on December 1961. The locomotive reached its destination in January 1962 and was displayed in Fairplex until November 2013. Union Pacific 4014 is currently in Union Pacific's Steam Shop in Cheyenne, Wyoming, awaiting extensive restoration work which is intended to return the engine to operational status. When 4014 officially returns to service, it will displace UP 3985 as the largest, heaviest and most powerful operational steam locomotive in the world.

History

UP 4014 was one of 25 4-8-8-4 class locomotives developed by Union Pacific and Alco to overcome issues with the preceding 4-6-6-4 Challenger class locomotives. It was determined that the goals that Union Pacific had set for its new class of locomotive could be achieved by making several changes to the existing Challenger design, including enlarging the firebox to approximately 235 by 96 inches (5.97 m × 2.44 m) (about 155 sq ft or 14.4 m²), lengthening the boiler, adding four driving wheels and reducing the size of the driving wheels from 69 to 68 in (1,753 to 1,727 mm).
