Aarhus Light Rail
The Aarhus Letbane (Aarhus light rail) is a light rail system in the city of Aarhus, Denmark. It is operated by the company Midttrafik. The first line opened in December 2017, but the system is under continuous development and expansion. Service on the intercity section Odder to Lisbjergskolen opened on August 25, 2018. A third intercity line to Grenå opened on 30 April 2019. More lines are being planned. On 8 May 2012, the Danish Parliament approved the construction of the first line; work to build Phase 1 commenced during September 2013. It was originally planned to open in August 2016, but this was delayed, in part due to legislative issues in relation to railway safety. Two types of rolling stock have been operated over the first line, conventional trams which are slower and restricted to only running along some parts of the route and hybrid tram-trains that can be operated on the conventional heavy rail network, the latter being used for the long-distance services.

Odense Letbane
The Odense Letbane (English: Odense Tramway) is a tram system in Odense, Denmark. The first phase opened on 28 May 2022. The tramway starts in Tarup, in the north-western part of Odense, and travels via the central train station, University of Southern Denmark, and the new hospital before reaching its final destination in Hjallese, in the southernmost part of the city. The first line consists of of tracks and has 26 stations. Expected number of passengers is 34,000 daily. The total budget is 3.3 billion Danish krone (2017 numbers). The tramway is financed by the Odense Municipality, the Danish State, and the Region of Southern Denmark. The planned second line consists of of tracks with a budget of 1.9 billion Danish krone. The city council has decided to work towards establishing a second line. However, there is no construction regulation or co-financing from the Danish state . History The political process The tramway in Odense was suggested for the first time in 200 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lloyd's Register
Lloyd's Register Group Limited (LR) is a technical and professional services organisation and a maritime classification society, wholly owned by the Lloyd’s Register Foundation, a UK charity dedicated to research and education in science and engineering. The organisation dates to 1760. Its stated aims are to enhance the safety of life, property, and the environment, by helping its clients (including by validation, certification, and accreditation) to improve the safety and performance of complex projects, supply chains and critical infrastructure. In July 2012, the organisation converted from an industrial and provident society to a company limited by shares, named Lloyd’s Register Group Limited, with the new Lloyd’s Register Foundation as the sole shareholder. At the same time the organisation gave to the Foundation a substantial bond and equity portfolio to assist it with its charitable purposes. It will benefit from continued funding from the group’s operating arm, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verordnung über Den Bau Und Betrieb Der Straßenbahnen
The ("Ordinance on the Construction and Operation of Street Railways" / light railway regulations), abbreviated as BOStrab, is a German law regulation governing the field of tramway, metro and light rail operations. The orders are enacted by the Federal Ministry of Transport based on enabling act through the General Railway Law ("", first issued on 29. March 1951). The supervisory authority is delegated to the Federal Railway Authority of Germany. The BOStrab regulations are not as strict as the EBO main railway regulations; for example the BOStrab does not specify a strict loading gauge to follow. A third law ESBO () covers narrow-gauge railway regulations. The distinctions for these light rail systems are slightly different from in the UK Tramways Act 1870 / Light Railways Act 1896. Some Stadtbahn systems are subject to both BOStrab and EBO regulations as their vehicles use both types of networks. This is common with tram-train systems - apart from a technical switch on th ...

Catenary
In physics and geometry, a catenary (, ) is the curve that an idealized hanging chain or cable assumes under its own weight when supported only at its ends in a uniform gravitational field. The catenary curve has a U-like shape, superficially similar in appearance to a parabola, which it is not. The curve appears in the design of certain types of arches and as a cross section of the catenoid—the shape assumed by a soap film bounded by two parallel circular rings. The catenary is also called the alysoid, chainette,MathWorld or, particularly in the materials sciences, funicular. Rope statics describes catenaries in a classic statics problem involving a hanging rope. Mathematically, the catenary curve is the graph of the hyperbolic cosine function. The surface of revolution of the catenary curve, the catenoid, is a minimal surface, specifically a minimal surface of revolution. A hanging chain will assume a shape of least potential energy which is a catenary. Galileo Galil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electro-diesel
An electro-diesel locomotive (also referred to as a dual-mode or bi-mode locomotive) is a type of locomotive that can be powered either from an electricity supply (like an electric locomotive) or by using the onboard diesel engine (like a diesel-electric locomotive). For the most part, these locomotives are built to serve regional, niche markets with a very specific purpose. Overview Electro-diesel locomotives are used to provide continuous journeys along routes that are only partly electrified without a change of locomotive, avoid extensive running of ''diesel under the wires'' (using a diesel locomotive where electrified lines are available), and giving solution where diesel engines are banned. They may be designed or adapted mainly for electric use, mainly for diesel use or to work well as either electric or diesel. Note that, as well as the electric multiple unit (EMU) and diesel multiple unit (DMU), where no discrete locomotive is present, an electro-diesel (bi-mode) ...

Electrification
Electrification is the process of powering by electricity and, in many contexts, the introduction of such power by changing over from an earlier power source. The broad meaning of the term, such as in the history of technology, economic history, and economic development, usually applies to a region or national economy. Broadly speaking, electrification was the build-out of the electricity generation and electric power distribution systems that occurred in Britain, the United States, and other now- developed countries from the mid-1880s until around 1950 and is still in progress in rural areas in some developing countries. This included the transition in manufacturing from line shaft and belt drive using steam engines and water power to electric motors. The electrification of particular sectors of the economy is called by terms such as ''factory electrification'', ''household electrification'', ''rural electrification'', ''aviation electrification'' or ''railway electrificati ...

Carbon Dioxide
Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

Kassel
Kassel (; in Germany, spelled Cassel until 1926) is a city on the Fulda River in northern Hesse, Germany. It is the administrative seat of the Regierungsbezirk Kassel and the district of the same name and had 201,048 inhabitants in December 2020. The former capital of the state of Hesse-Kassel has many palaces and parks, including the Bergpark Wilhelmshöhe, which is a UNESCO World Heritage Site.

History Kassel was first mentioned in 913 AD, as the place where two deeds were signed by King Conrad I. The place was called ''Chasella'' or ''Chassalla'' and was a fortification at a bridge crossing the Fulda river. There are several yet unproven assumptions of the name's origin. It could be derived from the ancient ''Castellum Cattorum'', a castle of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
