Hanscotte Centre-rail System
The Hanscotte system was a design for railway locomotives and track using, in addition to the conventional load-bearing driving wheels, pairs of horizontal driving wheels mounted underneath the locomotive and pressing inwards upon a central rail, to improve adhesion and Traction (engineering), traction. The engineer developed the system while working for Société de construction des Batignolles (SCB), Paris, in about 1904. SCB intended to use the system for braking very heavy trains, but the most notable deployment was on the Chemin de Fer du Puy-de-Dôme, a tourist light railway between Clermont Ferrand and the summit of the Puy de Dôme, Puy-de-Dôme, in 1906. Development In 1898 Hanscotte was working for the engineering company Société de Construction des Batignolles (SCB) (successor to Ernest Goüin et Cie., the company contracted to build Fell mountain railway system, Fell system centre-rail locomotives for the Mont Cenis Pass Railway in 1867). In 1904 he started work on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adhesion
Adhesion is the tendency of dissimilar particles or interface (matter), surfaces to cling to one another. (Cohesion (chemistry), Cohesion refers to the tendency of similar or identical particles and surfaces to cling to one another.) The forces that cause adhesion and cohesion can be divided into several types. The intermolecular forces responsible for the function of various kinds of stickers and sticky tape fall into the categories of chemical adhesion, dispersive adhesion, and diffusive adhesion. In addition to the cumulative magnitudes of these intermolecular forces, there are also certain emergent mechanical effects. Surface energy Surface energy is conventionally defined as the work (physics), work that is required to build an area of a particular surface. Another way to view the surface energy is to relate it to the work required to cleave a bulk sample, creating two surfaces. If the new surfaces are identical, the surface energy γ of each surface is equal to h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Mountain Railways
A mountain railway is a railway that operates in a mountain range, mountainous region. It may operate through the mountains by following mountain valleys and tunneling beneath mountain passes, or it may climb a mountain to provide transport to and from the summit. Mountain railways often use narrow gauge railways, narrow gauge tracks to allow for tight curves in the track and reduce tunnel size and structure gauge, and hence construction cost and effort. Where mountain railways need to climb steep gradients, they may use steep grade railway technology, or even operate as funicular railways.

History Of Tram Transport
History is the systematic study of the past, focusing primarily on the human past. As an academic discipline, it analyses and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a more general sense, the term ''history'' refers not to an academic field but to the past itself, times in the past, or to individual texts about the past. Historical research relies on primary and secondary sources to reconstruct past events and validate interpretations. Source criticism is used to evaluate these sources, assessing their authenticity, content, and reliability. Historians strive to integrate the perspectives of several sources to develop a ...
