Strømmens Værksted
Strømmens Værksted A/S was an industrial company based in Skedsmo, Norway, specialising in the production of rolling stock. Founded in 1873, it remains as a part of Bombardier Transportation. The plant is located just off Hovedbanen west of Strømmen Station. History The company was established as a mechanical workshop and an iron works in 1873 by engineer Wincentz Thurmann Ihlen, with the name W. Ihlen, Strømmen. The main product was railway cars, with the first being produced in 1874. The Ihlen family retained ownership of the company, with Nils Claus Ihlen taking over the works in 1883, changing the name to ''Strømmens Værksted'', and his sons Joakim and Alf Ihlen in 1908, who transformed it to a limited company.

Buffer (rail Transport)
A buffer is a part of the buffers-and-chain coupling system used on the railway systems of many countries, among them most of those in Europe, for attaching railway vehicles to one another. Description Fitted at the ends of the vehicle frames on the buffer beam, one at each corner, the buffers are projecting, shock-absorbing pads which, when vehicles are coupled, are brought into contact with those on the next vehicle. The buffer itself comprises the buffer plates which take the impact. The draw chain used between each pair of vehicles includes a screw which is tightened after coupling to shorten the chain and keep the buffers pressed together. Such is known as a 'screw coupling'. Historically, coupling chains were no more than that, a short length of heavy chain (typically three links long) with no adjustment. These would result in a 'loose-coupled train' in which the buffers of adjacent vehicles would only touch when the coupling chain was fully slack, such as when being pus ...

Railway Tires
The steel wheel of a steam locomotive and other older types of rolling stock were usually fitted with a steel tire (American English) or tyre (in British English, Australian English and others) to provide a replaceable wearing element on a costly wheel. Installation Replacing a whole wheel because of a worn contact surface was expensive, so older types of railway wheels were fitted with a replaceable steel tire. The tire is a hoop of steel that is fitted around the steel wheel centre. The tire is machined with a shoulder on its outer face to locate it on the wheel centre, and a groove on the inside diameter of the flange face. The inside diameter of the tire is machined to be slightly less than the diameter of the wheel centre on which it is mounted, to give an interference fit. The tire is fitted by heating to a controlled temperature, avoiding overheating. This causes the tire to expand. The wheel centre, usually already mounted on the axle, is lowered into the tire which i ...

Stavanger
Stavanger (, , American English, US usually , ) is a city and municipalities of Norway, municipality in Norway. It is the fourth largest city and third largest metropolitan area in Norway (through conurbation with neighboring Sandnes) and the administrative center of Rogaland county. The municipality is the fourth most populous in Norway. Located on the Stavanger Peninsula in southwest Norway, Stavanger counts its official founding year as 1125, the year the Stavanger Cathedral was completed. Stavanger's core is to a large degree 18th- and 19th-century wooden houses that are protected and considered part of the city's cultural heritage. This has caused the town center and inner city to retain a small-town character with an unusually high ratio of detached houses, and has contributed significantly to spreading the city's population growth to outlying parts of Greater Stavanger. The city's population rapidly grew in the late 20th century due to its oil industry. Stavanger is known ...

Oslo
Oslo ( , , or ; sma, Oslove) is the capital and most populous city of Norway. It constitutes both a county and a municipality. The municipality of Oslo had a population of in 2022, while the city's greater urban area had a population of in 2019, and the metropolitan area had an estimated population of in 2021. During the Viking Age the area was part of Viken. Oslo was founded as a city at the end of the Viking Age in 1040 under the name Ánslo, and established as a ''kaupstad'' or trading place in 1048 by Harald Hardrada. The city was elevated to a bishopric in 1070 and a capital under Haakon V of Norway around 1300. Personal unions with Denmark from 1397 to 1523 and again from 1536 to 1814 reduced its influence. After being destroyed by a fire in 1624, during the reign of King Christian IV, a new city was built closer to Akershus Fortress and named Christiania in honour of the king. It became a municipality ('' formannskapsdistrikt'') on 1 January 1838. The city fu ...

Nationalization
Nationalization (nationalisation in British English) is the process of transforming privately-owned assets into public assets by bringing them under the public ownership of a national government or state. Nationalization usually refers to private assets or to assets owned by lower levels of government (such as municipalities) being transferred to the state. Nationalization contrasts with privatization and with demutualization. When previously nationalized assets are privatized and subsequently returned to public ownership at a later stage, they are said to have undergone renationalization. Industries often subject to nationalization include the commanding heights of the economy – telecommunications, electric power, fossil fuels, railways, airlines, iron ore, media, postal services, banks, and water – though, in many jurisdictions, many such entities have no history of private ownership. Nationalization may occur with or without financial compensation to the former owners. ...

Gullfisk
Class B and Class E, normally referred to as ''Gullfisk'' (Norwegian for "goldfish"), were a class of 46 trams built by Strømmens Værksted and Skabo Jernbanevognfabrikk for Oslo Sporveier and Bærumsbanen of Oslo, Norway, in 1937 and 1939. They were the first aluminium trams to operate on the Oslo Tramway and the first bogie trams to operate on street lines. They had contemporary modern electronic equipment, a streamlined shape, and comfortable accommodation. Until 1964, they were also faster than any other Norwegian tramcar or suburban railcar. Six prototype trams were delivered by Strømmen in 1937, with four different motor solutions, from AEG, Siemens, Vickers and Norsk Elektrisk & Brown Boveri (NEBB). None of these were particularly successful, and the 40 serial production trams used conventional motors from ELIN. These were delivered in 1939, with 20 (class E) being used by Oslo Sporveier mainly on the Kjelsås Line, but also on other services. The remaining 20 trams (clas ...

Folding Seat
A folding seat is a seat that folds away so as to occupy less space. When installed on a transit bus, it makes room for a wheelchair or two. When installed on a passenger car, it provides extra seating. In churches, it may have a projection called a misericord, which offers some support to a person standing in front when the seat is folded. Folding seats may also be found in stadiums, arenas, theaters and auditoriums to facilitate entry and exit. Some folding seats in rapid transit may fold-down rather than fold up.

Seating Capacity
Seating capacity is the number of people who can be seated in a specific space, in terms of both the physical space available, and limitations set by law. Seating capacity can be used in the description of anything ranging from an automobile that seats two to a stadium that seats hundreds of thousands of people. The largest sporting venue in the world, the Indianapolis Motor Speedway, has a permanent seating capacity for more than 235,000 people and infield seating that raises capacity to an approximate 400,000. In transport In venues Safety is a primary concern in determining the seating capacity of a venue: "Seating capacity, seating layouts and densities are largely dictated by legal requirements for the safe evacuation of the occupants in the event of fire". The International Building Code specifies, "In places of assembly, the seats shall be securely fastened to the floor" but provides exceptions if the total number of seats is fewer than 100, if there is a substantial amo ...
