Ballastless Track
A ballastless track or slab track is a type of railway track infrastructure in which the traditional elastic combination of sleepers and ballast is replaced by a rigid construction of concrete or asphalt. It is considered the standard for high-speed and heavy haul railway lines. It is also commonly used for urban tramways. Characteristics In ballastless tracks, the rails are either discretely supported or continuously supported. Discretely supported rails sit on elastomeric pads and are rigidly fastened to special types of concrete sleepers. These sleepers are themselves set directly in concrete or in rubber 'boots' and both are then set in concrete. Continuously supported rails are generally fixed in slots in the concrete slab and called Embedded Rail Track. The rails, which can be either traditional Vignole Rails with a head, web and foot, or block rails with no web, are either cast into the slots by an elastic compound or surrounded by a close-fitting boot before being fix ...

Feste Fahrbahn FFBögl
Feste is a fictional character in William Shakespeare's comedy ''Twelfth Night''. He is a fool (royal jester) attached to the household of the Countess Olivia. He has apparently been there for some time, as he was a "fool that the Lady Olivia's father took much delight in" (2.4). Although Olivia's father has died within the last year, it is possible that Feste approaches or has reached middle age, though he still has the wit to carry off good 'fooling' when he needs to, and the voice to sing lustily or mournfully as the occasion demands. He is referred to by name only once during the play, in answer to an inquiry by Orsino of who sang a song that he heard the previous evening. Curio responds "Feste, the jester, my lord; a fool that the lady Olivia's father took much delight in. He is about the house" (2.4). Throughout the rest of the play, he is addressed only as "Fool," while in the stage directions he is mentioned as "Clown." Feste seems to leave Olivia's house and return at ...

Drainage
Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess water. The internal drainage of most agricultural soils can prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need artificial drainage to improve production or to manage water supplies. History Early history The Indus Valley Civilization had sewerage and drainage systems. All houses in the major cities of Harappa and Mohenjo-daro had access to water and drainage facilities. Waste water was directed to covered gravity sewers, which lined the major streets. 18th and 19th century The invention of hollow-pipe drainage is credited to Sir Hugh Dalrymple, who died in 1753. Current practices Simple infrastructure such as open drains, pipes, and berms are still common. In modern times, more complex structures involving substantial earthworks and new technologies have been common as well. Geotextiles New storm water drainag ...

Rheda-Wiedenbrück Station
Rheda-Wiedenbrück station is a passenger station in the Westphalian town of Rheda-Wiedenbrück in the German state of North Rhine-Westphalia. It lies on the Hamm–Minden railway, one of the most heavily trafficked lines in Germany. The Warendorf Railway branches off to the west to Münster. The section of the Warendorf Railway running east to Lippstadt is now closed. The station is located north of central Rheda. History As part of the construction of its trunk line from Cologne via the Ruhr valley to Minden, the Cologne-Minden Railway Company (German, old spelling: ''Cöln-Mindener Eisenbahn-Gesellschaft'', CME) opened the Hamm–Minden line on 15 October 1847, including the Rheda-Wiedenbrück station, originally called ''Rheda in Westfalen''. After the nationalisation of the nominally private railway companies, the section from Warendorf via Rheda to Lippstadt of the Warendorf Railway was completed on 25 June 1887, originally crossing the railway station and the existing l ...

Green Track
Green track (also grassed track or lawn track) is a type of railway track in which the track bed and surrounding area are planted with sod, grass turf or other vegetation as ground cover. It is a popular way of making railways more visually appealing, particularly for trams and light rail, and providing additional urban green space. Aside from the visual improvement, the vegetation provides a number of positive effects, such as noise control, noise reduction, less air pollution, Surface runoff, rainwater runoff mitigation, and reduced urban heat island, urban heat island effect. History The first green tracks were installed in 1905 along in Berlin. Due to the technical challenges they posed, many green tracks were phased out in the following decades, but beginning in the mid-1980s, green tracks have seen a resurgence. Impact Green tracks have a number of positive impacts on the urban environment. Green tracks reduce surface runoff by retaining an estimated 50-70% of precipitati ...

Rapid Transit
Rapid transit or mass rapid transit (MRT) or heavy rail, commonly referred to as metro, is a type of high-capacity public transport that is generally built in urban areas. A grade separation, grade separated rapid transit line below ground surface through a tunnel can be regionally called a subway, tube, metro or underground. They are sometimes grade-separated on elevated railways, in which case some are referred to as el trains – short for "elevated" – or skytrains. Rapid transit systems are usually electric railway, electric railways, that unlike buses or trams operate on an exclusive right-of-way (transportation), right-of-way, which cannot be accessed by pedestrians or other vehicles. Modern services on rapid transit systems are provided on designated lines between metro station, stations typically using electric multiple units on railway tracks. Some systems use rubber-tyred metro, guided rubber tires, magnetic levitation (''maglev''), or monorail. The stations typica ...

Tram
A tram (also known as a streetcar or trolley in Canada and the United States) is an urban rail transit in which Rolling stock, vehicles, whether individual railcars or multiple-unit trains, run on tramway tracks on urban public streets; some include segments on segregated Right-of-way (property access), right-of-way. The tramlines or tram networks operated as public transport are called tramways or simply trams/streetcars. Because of their close similarities, trams are commonly included in the wider term ''light rail'', which also includes systems separated from other traffic. Tram vehicles are usually lighter and shorter than Main line (railway), main line and rapid transit trains. Most trams use electrical power, usually fed by a Pantograph (transport), pantograph sliding on an overhead line; older systems may use a trolley pole or a bow collector. In some cases, a contact shoe on a third rail is used. If necessary, they may have dual power systems—electricity in city stre ...

Light Railway
A light railway is a Rail transport, railway built at lower costs and to lower standards than typical "heavy rail": it uses lighter-weight track, and may have more Grade (slope), steep gradients and Minimum railway curve radius, tight curves to reduce civil engineering costs. These lighter standards allow lower costs of operation, at the price of lower vehicle capacity. Narrow gauge The precise meaning of the term "light railway" varies by geography and context. In countries where a single standard gauge is dominant, the term light railway does not imply a narrow gauge railway. Most narrow gauge railways operate as light railways, but not all light railways need be narrow gauge. After Charles Easton Spooner, Spooner's development of steam haulage for narrow gauge railways, the prevailing view was that the gauge should be tailored according to the traffic: "The nearer the machine is apportioned to the work it has to do the cheaper will that work be done." From the 1890s, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Life-cycle Cost
Whole-life cost is the total cost of ownership over the life of an asset. The concept is also known as life-cycle cost (LCC) or lifetime cost, and is commonly referred to as "cradle to grave" or "womb to tomb" costs. Costs considered include the financial cost which is relatively simple to calculate and also the environmental and social costs which are more difficult to quantify and assign numerical values. Typical areas of expenditure which are included in calculating the whole-life cost include planning, design, construction and acquisition, operations, maintenance, renewal and rehabilitation, depreciation and cost of finance and replacement or disposal. Financial Whole-life cost analysis is often used for option evaluation when procuring new assets and for decision-making to minimize whole-life costs throughout the life of an asset. It is also applied to comparisons of actual costs for similar asset types and as feedback into future design and acquisition decisions. The prim ...

Tire
A tire (North American English) or tyre (Commonwealth English) is a ring-shaped component that surrounds a Rim (wheel), wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide Traction (engineering), traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, providing a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tires provide a footprint, called a contact patch, designed to match the vehicle's weight and the bearing on the surface that it rolls over by exerting a pressure that will avoid deforming the surface. The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric, and wire, along with carbon black and other chemical compounds. They consist of a tire tread, tread and a body. The tread provides Traction (engineering), traction while the body provides containment for a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bus Lane
A bus lane or bus-only lane is a lane restricted to buses, generally to speed up public transport that would be otherwise held up by traffic congestion. The related term busway describes a roadway completely dedicated for use by buses, whilst bus gate describes a short bus lane often used as a short cut for public transport. Bus lanes are a key component of a high-quality bus corridor (QBC) and bus rapid transit (BRT) network, improving bus travel speeds and reliability by reducing delay caused by other traffic. A dedicated bus lane may occupy only part of a roadway which also has lanes serving general automotive traffic; in contrast to a transit mall which is a pedestrianized roadway also served by transit. History The first bus lane is often erroneously attributed to Chicago, where in 1939 Sheridan Road was installed with reversible lanes north of Foster Avenue. The setup consisted of three-lanes towards the peak direction (south in the morning; north in the evening), and on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
