W-class Melbourne Tram
The W-class trams are a family of electric trams built by the Melbourne & Metropolitan Tramways Board (MMTB) between 1923 and 1956. Over the 33 years of production, 752 vehicles spanning 12 sub-classes were constructed, the majority at the MMTB's Preston Workshops. A small fleet continue to operate on the tramway network of Melbourne, Australia, where they are used on the City Circle tourist route. The W-class tram is a cultural icon to Melbourne: those that remain in the city are classified by the National Trust of Australia. As well as Melbourne, W-class trams operate on tourist and heritage systems across the world. A number of older variants have been withdrawn from service and later sent to cities such as Copenhagen, San Francisco, Savannah and Seattle, and by private enthusiasts. In 2018, 134 W-class trams were offered to the Australian public for new uses. As of December 2021, only 13 W class trams remain in service in Melbourne, all of which are W8 trams operating on ...

Victorian Railways W Class
The W class are a diesel-hydraulic shunting locomotive ordered and operated by the Victorian Railways of Australia. History In mid 1957, the Victorian Railways called for tenders for a fleet of 25 diesel-hydraulic locomotives rated at . Tulloch, based in Rhodes, New South Wales, won the contract with an offer for West German-style locomotives, using a Mercedes V12 diesel engine developing which was coupled to a Krupp 2W1D46 hydraulic transmission powering the centre axle, with the leading and trailing axles powered via connecting rods. All 25 engines entered service in the year from December 1959. Tulloch expected a repeat order for a further 25 units from the Victorian Railways, and also built a standard gauge version numbered 7101 as a demonstrator unit for the New South Wales Railways. However, the latter system rejected the design as unsuitable, so that unit was sold to the Victorian Railways and used for construction trains on the Albury to Melbourne standard gauge lin ...

WAGR W Class
The WAGR W class is a class of 4-8-2 steam locomotives operated by the Western Australian Government Railways (WAGR) between 1951 and 1972. Engineering Background The class was first proposed by Chief Mechanical Engineer Frederick Mills in 1947. However, the death of Mills in 1949 put a hold on the project, with his successor Charles Clarke, taking up the project on his appointment later that year. Mills had requested Beyer, Peacock & Co to reserve capacity for their construction when the design was first proposed, however, by the time Clarke took over, Beyer, Peacock & Co had identified a number of possible problems with the design. This led to a meeting in the United Kingdom in 1950, the outcome of which was a substantial redesign of the locomotive. The resultant locomotive included many proprietary boiler and ancillary fittings, as well as parts interchange ability. The firebox was substantially altered to take into account the properties of Collie coal. This included a com ...

Premium Economy
Premium economy class, also known as elite economy class or economy plus class, is a travel class offered on some airlines. It is usually positioned between standard economy class and business class in terms of price, comfort, and available amenities. In 1991, EVA Air was the first to introduce ''Evergreen Class'' (later renamed Elite Class, and then to Premium Economy Class), becoming the first airline to offer this class of service. It was widely acknowledged that the premium economy class has become a standard reflection of what the economy class was like several decades ago. In some countries, this class has emerged as a response from governments and companies requiring economy class for travel done by staff. Characteristics As of 2018, the term has not been standardised among airlines, and varies significantly between domestic and international flights, as well as between low-cost or regional airlines and other airlines. Premium economy is sometimes limited to expanded ...
