SAR Class 5M2
The Class 5M2 and Class 5M2A are electric multiple units that are used to provide commuter rail services by Metrorail in the major cities of South Africa. The original Class 5M2 trainsets were built for the South African Railways by Metro-Cammell between 1958 and 1960. Most of those in use today, however, are of Class 5M2A, built to the same design by Union Carriage & Wagon (UCW) from 1962 to 1985; a total of 4,447 coaches were built by UCW. Although most of Metrorail's services are still operated by 5M2As, they are being progressively rebuilt into the new Class 10M3, 10M4 and 10M5. Class 5M2A coaches are stripped down to the underframe, which is then used as the base for the Class 10Ms. Specifications The Class 5M2s operate on the track that is standard throughout Southern Africa. The motor coaches draw 3,000 volt direct current from an overhead pantograph; they have a power output of and produce of tractive effort. The maximum speed of a 5M2 trainset is .

Metrorail Western Cape
Metrorail Western Cape is a network of commuter and suburban rail services in the City of Cape Town Metropolitan Municipality (metropolitan area of Cape Town) and in the surrounding towns of Malmesbury, Paarl, Stellenbosch and Wellington in the Western Cape province of South Africa. It is operated by Metrorail, which operates commuter rail services in the major cities of South Africa. The network is fairly comprehensive, however some key areas have no service, notably the Atlantic Seaboard, Western Seaboard and Durbanville. There are 85 operational trainsets, made up of 1094 coaches. There are 671 scheduled trains per weekday, operating over of track to 122 stations and 4 halts. In 2018 there were around 500,000 daily users of the service. The services are divided into three areas, each of which has various branches. All services either commence or terminate at the main Cape Town station in the centre of the city, which has 24 platforms. All services are by electric multi ...

South African Railways
Transnet Freight Rail is a South African rail transport company, formerly known as Spoornet. It was part of the South African Railways and Harbours Administration, a state-controlled organisation that employed hundreds of thousands of people for decades from the first half of the 20th century and was widely referred to by the initials SAR&H (SAS&H in Afrikaans). Customer complaints about serious problems with Transnet Freight Rail's service were reported in 2010. Its head office is in Inyanda House in Parktown, Johannesburg. History Railways were first developed in the area surrounding Cape Town and later in Durban around the 1840s. The first line opened in Durban on 27 June 1850. The initial network was created to serve the agricultural production area between Cape Town and Wellington. The news that there were gold deposits in the Transvaal Republic moved the Cape Colony Government (supported by British Government) to link Kimberley as soon as possible by rail to Cape Town ...

Electric Multiple Units Of South Africa
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...

Tare Weight
Tare weight , sometimes called unladen weight, is the weight of an empty vehicle or container. By subtracting tare weight from gross weight ( laden weight), one can determine the weight of the goods carried or contained (the net weight). Etymology The word '' tare'' originates from the Middle French word 'wastage in goods, deficiency, imperfection' (15th ), from Italian , from Arabic , lit. 'thing deducted or rejected', from 'to reject'. Usage This can be useful in computing the cost of the goods carried for purposes of taxation or for tolls related to barge, rail, road, or other traffic, especially where the toll will vary with the value of the goods carried (''e.g.'', tolls on the Erie Canal). Tare weight is often published upon the sides of railway cars and transport vehicles to facilitate the computation of the load carried. Tare weight is also used in body composition assessment when doing underwater weighing.hydrostatic_weighing/ref> Tare_weight_is_accounted_for_in_ ...

Standing Passenger
In urban public transport, provision is made for standing passengers, often called straphangers or standees, to rationalize operation and to provide extra capacity during rush hour. Occurrence On crowded rapid transit urban lines, while most travelers may be seated during off-peak services, only a limited proportion will be seated during the peak services. The longer the journey, the less willing passengers are to stand. On intercity rail or coach services, the willingness among passengers to stand is often low, or it may even be prohibited, with reserved seating to ensure that all passengers can be seated. In aviation, safety measures require all passengers and crew to be seated during take-off and landing, so airlines do not allow passengers to travel without a seat. However, in 2010, Ryanair, a low-cost airline proposed a "vertical seat" design for use by standing passengers on its aircraft.The Telegraph (London)"Ryanair to sell £5 tickets for standing-room only flights" La ...

Tractive Effort
As used in mechanical engineering, the term tractive force can either refer to the total traction a vehicle exerts on a surface, or the amount of the total traction that is parallel to the direction of motion. In railway engineering, the term tractive effort is often used synonymously with tractive force to describe the pulling or pushing capability of a locomotive. In automotive engineering, the terms are distinctive: tractive effort is generally higher than tractive force by the amount of rolling resistance present, and both terms are higher than the amount of drawbar pull by the total resistance present (including air resistance and grade). The published tractive force value for any vehicle may be theoretical—that is, calculated from known or implied mechanical properties—or obtained via testing under controlled conditions. The discussion herein covers the term's usage in mechanical applications in which the final stage of the power transmission system is one ...

Pantograph (rail)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. By contrast, battery electric buses and trains are charged at charging stations. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad The familiar diamond-shaped roller pantograph was devised and patented b ...

Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...
