The transport portal
Transport is the movement of people and goods from one place to another. The term is derived from the Latin trans ("across") and portare ("to carry"). Industries which have the business of providing transport equipment, transport services or transport are important in most national economies, and are referred to as transport industries. The field can be divided into infrastructure, vehicles, and operations. Infrastructure consists of the fixed installations necessary for transport, and may be roads, railways, airways, waterways, canals and pipelines or terminals such as airports, railway stations, bus stations and seaports. Vehicles traveling on the network include automobiles, bicycles, buses, trains, people and aircraft. Operations deal with the way the vehicles are operated, and the procedures set for this purpose including the financing, legalities and policies.
The London congestion charge is a fee charged on most motor vehicles operating within the Congestion Charge Zone (CCZ) in central London between 07:00 and 18:00 (Monday-Friday only). The charge, which was introduced on 17 February 2003, remains one of the largest congestion charge zones in the world despite the cancellation of the Western Extension which operated between February 2007 and January 2011. The charge aims to reduce congestion, and to raise investment funds for London's transport system.
The standard charge is £10 for each day, for each non-exempt vehicle that travels within the zone with a penalty of between £60 and £187 levied for non-payment. Enforcement is primarily based on automatic number plate recognition (ANPR). Transport for London (TfL) is responsible for the charge which has been operated by IBM since 1 November 2009.
A roundhouse is a building used by railroads for servicing locomotives. Roundhouses are large, circular or semicircular structures that were traditionally located surrounding or adjacent to turntables. The defining feature of the traditional roundhouse was the turntable, which facilitates access when the building is used for repair facilities or for storage of steam locomotives. Early steam locomotives normally travelled forwards only; although reverse operations capabilities were soon built into locomotive mechanisms, the controls were normally optimized for forward travel, and the locomotives often could not operate as well in reverse. Some passenger cars, such as observation cars, were also designed as late as the 1960s for operations in a particular direction. A turntable allowed a locomotive or other rolling stock to be turned around for the return journey.
