PRR I1s
The Pennsylvania Railroad (PRR) class I1s steam locomotives were the largest class of 2-10-0 "Decapods" in the United States. From 1916 to 1923, 598 locomotives were produced (123 at the railroad’s Altoona Works and 475 at Baldwin Locomotive Works). They were the dominant freight locomotive on the system until World War II and remained in service until 1957. Nicknames for the type included ''Decs'' and ''Hippos'', the latter due to their large boiler. The I1s design was much larger than the 2-10-0 design that preceded it, taking advantage of the PRR's heavy trackage and high allowed axle load, with a wide, free-steaming boiler. Large cylinders enabled the I1s to apply that power to the rails. However, the large boiler limited the size of the driving wheels, which made it impossible to mount counterweights large enough to balance the piston thrusts. As a result, they were hard riding at anything but low speeds, prone to slipping, and unpopular with crews. The locomotives were know ...

Dock (maritime)
The word dock () in American English refers to one or a group of human-made structures that are involved in the handling of boats or ships (usually on or near a shore). In British English, the term is not used the same way as in American English; it is used to mean the area of water that is next to or around a wharf or quay. The exact meaning varies among different variants of the English language. "Dock" may also refer to a dockyard (also known as a shipyard) where the loading, unloading, building, or repairing of ships occurs. History The earliest known docks were those discovered in Wadi al-Jarf, an ancient Egyptian harbor, of Pharaoh Khufu#Wadi al-Jarf, Khufu, dating from c.2500 BC located on the Red Sea coast. Archaeologists also discovered anchors and storage jars near the site. A dock from Lothal in India dates from 2400 BC and was located away from the main current (water), current to avoid deposition of silt. Modern oceanographers have observed that the ancient Indu ...

Drag Freight
A drag freight is a long, slow, high-tonnage Rail transport, railroad train, often carrying commodities such as coal or ore. Compared to "fast freight" trains, drag freight trains have a very low power-to-weight ratio, making them somewhat unpredictable on steep grades or hilly routes. This causes many dispatchers to be extremely conservative with how they handle drag freights, especially when they share lines with higher priority fast freights and passenger trains. Power Before and during World War I, WWI and into the 1920s, large locomotives such as the 2-8-2 Mikado or mainly larger types like Articulated locomotives, articulated locomotives or larger rigid-frame wheel arrangements such as the 2-10-4 Texas were typically used for drag freight operations. After the railroads dieselized, heavy duty diesel locomotives (typically six-axle units, to improve adhesion) were used for the drag freights. Multiple unit operations allowed one person to control multiple locomotives. As ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asbestos
Asbestos ( ) is a group of naturally occurring, Toxicity, toxic, carcinogenic and fibrous silicate minerals. There are six types, all of which are composed of long and thin fibrous Crystal habit, crystals, each fibre (particulate with length substantially greater than width) being composed of many microscopic "fibrils" that can be released into the atmosphere by Abrasion (mechanical), abrasion and other processes. Inhalation of asbestos fibres can lead to various dangerous lung conditions, including mesothelioma, asbestosis, and lung cancer. As a result of these health effects, asbestos is considered a serious Health hazard, health and safety hazard. Archaeological studies have found evidence of asbestos being used as far back as the Stone Age to strengthen ceramic pots, but large-scale mining began at the end of the 19th century when manufacturers and builders began using asbestos for its desirable physical properties. Asbestos is an excellent Thermal insulation, thermal and In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Air Brake
A railway air brake is a railway brake power braking system with compressed air as the operating medium. Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's invention. In various forms, it has been nearly universally adopted. The Westinghouse system uses air pressure to charge air reservoirs (tanks) on each car. Full air pressure causes each car to release the brakes. A subsequent reduction or loss of air pressure causes each car to apply its brakes, using the compressed air stored in its reservoirs. Overview Straight air brake In the air brake's simplest form, referred to as a ''straight air system'', compressed air is directed to a ''brake cylinder'', causing its piston to apply force to mechanical linkage, which linkage is conventionally referred to as the ''brake rigging'' (see illu ...

Wilmerding, Pennsylvania
Wilmerding is a borough in Allegheny County, Pennsylvania, United States. The population was 1,781 at the 2020 census. It is located southeast of Pittsburgh. At the start of the twentieth century, it had extensive foundries and machine shops of the Westinghouse Air Brake Company. Wilmerding is adjacent to the borough of Turtle Creek, which takes its name from a small stream that flows past both places.

Westinghouse Air Brake Company
The Westinghouse Air Brake Technologies Corporation (WABCO) was an American company founded on September 28, 1869 by George Westinghouse in Pittsburgh, Pennsylvania. Earlier in the year he had invented the railway air brake in New York state. After having manufactured equipment in Pittsburgh for a number of years, he began to construct facilities and plants east of the city where homes for his employees were built. In 1889, the air brake manufacturing facility was moved to Wilmerding, Pennsylvania, and the company's general office building was built there in 1890. In 1921 the company began manufacturing a modified air brake system for installation in trucks and heavy vehicles. In 1953 WABCO entered the heavy equipment marketplace, buying the assets of leading equipment designer R.G LeTourneau. An entity known as "LeTourneau-Westinghouse" sold a range of innovative products, including scrapers, cranes and bulldozers until 1967, when it shortened its name to "Wabco". In 196 ...
