Richmond Union Passenger Railway
The Richmond Union Passenger Railway, in Richmond, Virginia, was the first practical electric Tram, trolley (tram) system, and set the pattern for most subsequent electric trolley systems around the world. It is an Institute of Electrical and Electronics Engineers, IEEE milestone in engineering. The Richmond system was not the first attempt to operate an electric trolley. According to the IEEE, there were at least 74 earlier attempts to provide electric trolley service in over 60 communities in North America, the United Kingdom, and continental Europe. However, these earlier attempts were not reliable enough to replace the existing animal-hauled street railways. The Richmond system was designed by Frank Julian Sprague. After trials in late 1887, it began regular operation on February 2, 1888, with 10 streetcars. Electric power was supplied through overhead trolley wires (450 volts) for two motors on each car. Large cars weighed , provided 40 seats, and carried up to 100 passen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GRTC Pulse
The GRTC Pulse (often abbreviated as The Pulse) is a bus rapid transit line in Richmond, Virginia, United States. The line runs along U.S. Route 250, Broad Street and U.S. Route 33, Main Street in central Richmond, between The Shops at Willow Lawn and Rockett's Landing. It opened on June 24, 2018, and is the third bus rapid transit service to be constructed in Virginia. The Pulse is the first regional rapid transit system to serve Richmond since 1949. The Institute for Transportation and Development Policy (ITDP), under its BRT Standard, has given the Pulse corridor a Bronze ranking. History Before the bus rapid transit system, the city was served by conventional buses operated by the Greater Richmond Transit Company. Bus service in the city began on February 1, 1923, and replaced the city's streetcar system when it ceased operations in 1949. From 1888 until 1949, the city was also served by streetcars via the Richmond Union Passenger Railway. Original plans for rapid tra ...

Theatrical District, Richmond, Virginia, 1923
Theatre or theater is a collaborative form of performing art that uses live performers, usually actors or actresses, to present the experience of a real or imagined event before a live audience in a specific place, often a stage. The performers may communicate this experience to the audience through combinations of gesture, speech, song, music, and dance. Elements of art, such as painted scenery and stagecraft such as lighting are used to enhance the physicality, presence and immediacy of the experience. The specific place of the performance is also named by the word "theatre" as derived from the Ancient Greek θέατρον (théatron, "a place for viewing"), itself from θεάομαι (theáomai, "to see", "to watch", "to observe"). Modern Western theatre comes, in large measure, from the theatre of ancient Greece, from which it borrows technical terminology, classification into genres, and many of its themes, stock characters, and plot elements.

Minimum Railway Curve Radius
The minimum railway curve radius is the shortest allowable design radius for the centerline of railway tracks under a particular set of conditions. It has an important bearing on construction costs and operating costs and, in combination with superelevation (difference in elevation of the two rails) in the case of train tracks, determines the maximum safe speed of a curve. The minimum radius of a curve is one parameter in the design of railway vehicles as well as trams; monorails and automated guideways are also subject to a minimum radius. History The first proper railway was the Liverpool and Manchester Railway, which opened in 1830. Like the tram roads that had preceded it over a hundred years, the L&M had gentle curves and gradients. Reasons for these gentle curves include the lack of strength of the track, which might have overturned if the curves were too sharp causing derailments. The gentler the curves, the greater the visibility, thus boosting safety via increased ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transportation In Richmond, Virginia
Transportation in Richmond, Virginia and its immediate surroundings include land, sea and air modes. This article includes the independent city and portions of the contiguous counties of Henrico and Chesterfield. While almost all of Henrico County would be considered part of the Richmond area, southern and eastern portions of Chesterfield adjoin the three smaller independent cities of Petersburg, Hopewell, and Colonial Heights, collectively commonly called the Tri-Cities area. A largely rural section of southwestern Chesterfield may be considered not a portion of either suburban area. Richmond-Petersburg metropolitan area is considered by many criteria to include the Tri-Cities area and many more surrounding counties, incorporated towns, and unincorporated communities. (For information on this larger area, see Richmond-Petersburg MSA). Transportation history Antebellum Richmond's transportation history dates to the early 17th century. The Virginia Colony, established at Jam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Companies Disestablished In 1949
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facilit ...

Light Rail In Virginia
Light or visible light is electromagnetic radiation that can be perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarization. Its speed in a vacuum, 299 792 458 metres a second (m/s), is one of the fundamental constants of nature. Like all types of electromagnetic radiation, visible light propagates by massless elementary particles called photons that represents the quanta of electromagnetic field, and can be analyzed as both waves and particle ...

West End Street Railway
The West End Street Railway was a streetcar company that operated in Boston, Massachusetts and several surrounding communities in the late nineteenth century. Originally an offshoot of a land development venture, the West End rose to prominence when it merged several independent streetcar companies into a single organization, and over the next decade it was the primary operator of public street transit within the Boston area. During this time, the company maintained one of the largest street railway systems in the world, the first unified streetcar system in the United States, and first electrified system in a major US city. The West End remained in independent operation until 1897, when it leased its entire line to the Boston Elevated Railway. It was formally consolidated into the Boston Elevated in 1922. History Foundation The original purpose of the West End was to provide service to a speculative land venture in western Boston and Brookline. In the mid-1880s a syndicate of ...

Degree Of Curvature
Degree of curve or degree of curvature is a measure of curvature of a circular arc used in civil engineering for its easy use in layout surveying. Definition The degree of curvature is defined as the central angle to the ends of an agreed length of either an arc or a chord; various lengths are commonly used in different areas of practice. This angle is also the change in forward direction as that portion of the curve is traveled. In an ''n''-degree curve, the forward bearing changes by ''n'' degrees over the standard length of arc or chord. Usage Curvature is usually measured in radius of curvature. A small circle can be easily laid out by just using radius of curvature, but degree of curvature is more convenient for calculating and laying out the curve if the radius is large as a kilometer or a mile, as it needed for large scale works like roads and railroads. By using degrees of curvature, curve setting can be easily done with the help of a transit or theodolite and a chai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
