British Rail Class 93 (Stadler)
The British Rail Class 93 is a tri-mode locomotive being built by Stadler Rail in Valencia. They will be an evolution of the Class 88 bi-mode locomotives which were built by Stadler for Direct Rail Services. Three different power sources will be used to power the locomotive – 25kVAC overhead electric power, or a diesel engine supplemented by a battery – allowing the locomotive to be used on both electrified and non-electrified lines. Rail Operations Group have ordered 30 locomotives, with the first deliveries scheduled for 2023. Development Background Historically, the vast majority of freight trains on Britain's railways have used diesel propulsion since the 1960s. During the late 2010s, as part of wider efforts to pursue carbon neutral operations, the Department for Transport (DfT) stated its long term goal of eliminating diesel-only traction from Britain's railways by 2040, despite only 46.5 per cent of all lines being electrified. However, due to a lack of governm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rendering (computer Graphics)
Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. The resulting image is referred to as the render. Multiple models can be defined in a ''scene file'' containing objects in a strictly defined language or data structure. The scene file contains geometry, viewpoint, texture, lighting, and shading information describing the virtual scene. The data contained in the scene file is then passed to a rendering program to be processed and output to a digital image or raster graphics image file. The term "rendering" is analogous to the concept of an artist's impression of a scene. The term "rendering" is also used to describe the process of calculating effects in a video editing program to produce the final video output. Rendering is one of the major sub-topics of 3D computer graphics, and in practice it is always connected to the others. It is the last major step in the gr ...

Carbon Neutral
Carbon neutrality is a state of net-zero carbon dioxide emissions. This can be achieved by balancing emissions of carbon dioxide with its removal (often through carbon offsetting) or by eliminating emissions from society (the transition to the "post-carbon economy"). The term is used in the context of carbon dioxide-releasing processes associated with transportation, energy production, agriculture, and industry. Although the term "carbon neutral" is used, a carbon footprint also includes other greenhouse gases, measured in terms of their carbon dioxide equivalence. The term climate-neutral reflects the broader inclusiveness of other greenhouse gases in climate change, even if CO2 is the most abundant. The term "net zero" is increasingly used to describe a broader and more comprehensive commitment to decarbonization and climate action, moving beyond carbon neutrality by including more activities under the scope of indirect emissions, and often including a science-based target on ...

Regenerative Braking
Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy into a form that can be either used immediately or stored until needed. In this mechanism, the electric traction motor uses the vehicle's momentum to recover energy that would otherwise be lost to the brake discs as heat. This method contrasts with conventional braking systems. In those systems, the excess kinetic energy is converted to unwanted and wasted heat due to friction in the brakes, or with rheostatic brakes, where the energy is recovered by using electric motors as generators but is immediately dissipated as heat in resistors. In addition to improving the overall efficiency of the vehicle, regeneration can significantly extend the life of the braking system as the mechanical parts will not wear out quickly. General principle The most common form of regenerative brake involves an electric motor functioning as an electric generator. In elect ...

Lithium-titanate Battery
The lithium-titanate or lithium-titanium-oxide (LTO) battery is a type of rechargeable battery which has the advantage of being faster to charge than other lithium-ion batteries but the disadvantage of having a much lower energy density. Uses Titanate batteries are used in certain Japanese-only versions of Mitsubishi's i-MiEV electric vehicle as well as Honda's EV-neo electric bike and Fit EV. They are also used in the Tosa concept electric bus. Because of the battery's high level of safety and recharge capabilities, LTO batteries are used in car audio applications as well as mobile medical devices. An LTO battery is also used in the S-Pen that comes with the Samsung Galaxy Note 20 Ultra 5G. According to a Weatherflow Co. article, the Tempest weather-station device contains a 1300mAh LTO battery, charged via four solar panels, requiring "at least 4 hours of adequate sunlight every two weeks." Chemistry A lithium-titanate battery is a modified lithium-ion battery that uses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Emission Standards
The European emission standards are vehicle emission standards for pollution from the use of new land surface vehicles sold in the European Union and EEA member states and the UK, and ships in EU waters. The standards are defined in a series of European Union directives staging the progressive introduction of increasingly stringent standards. , the standards do not include non-exhaust emissions such as particulates from tyres and brakes. Details of Euro 7 have been postponed to 12 October 2022. Background In the European Union, emissions of nitrogen oxides (), total hydrocarbon (THC), non-methane hydrocarbons (NMHC), carbon monoxide (CO) and particulate matter (PM) are regulated for most vehicle types, including cars, trucks (lorries), locomotives, tractors and similar machinery, barges, but excluding seagoing ships and aeroplanes. For each vehicle type, different standards apply. Compliance is determined by running the engine at a standardised test cycle. Non-co ...

Turbocharged
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to produce more power for a given engine displacement, displacement. The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gasses, whereas a supercharger is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. History Prior to the invention of the turbocharger, forced induction was only possible using mechanically-powered superchargers. Use of superchargers began in 1878, when sev ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Last Mile (transportation)
Last mile in supply chain management and transportation planning is the last leg of a journey comprising the movement of people and goods from a transportation hub to a final destination. "Last mile" was adopted from the telecommunications industry which faced difficulty connecting individual homes to the main telecommunications network. Similarly, in supply chain management last-mile describes the difficult last part in the transportation of people and packages from hubs to final destinations. Last-mile delivery is an increasingly studied field as the number of business-to-consumer (b2c) deliveries grow especially from e-commerce companies in freight transportation, and ride-sharing companies in personal transportation. Some challenges of last-mile delivery include minimizing cost, ensuring transparency, increasing efficiency, and improving infrastructure. History "Last mile" was originally used in the telecommunications industry to describe the difficulty of connecting end u ...

British Rail Class 68
The Class 68 is a type of mainline mixed traffic diesel-electric locomotive manufactured by Stadler Rail (and previously by Vossloh España) for Direct Rail Services (DRS) in the United Kingdom. The design is derived from the Stadler Eurolight, and Stadler's product name for this variant is the ''UKLight''. On 5 January 2012, DRS announced the placement of an order for fifteen Class 68 locomotives, the first of which arriving in the UK during January 2014. DRS testing determined the type to have satisfied its specification and to be suitable for operations. The first batch of Class 68s was quickly followed by a second batch, also intended for DRS and the first to be built by Stadler; the delivery of these units was completed during April 2016. A third batch of Class 68s was also ordered, deliveries of which were completed during July 2017. The Class 68 has since been followed by two closely-associated locomotives, the Class 88 and Class 93. Since its introduction in 2014, t ...

British Rail Class 66
The Class 66 is a type of six-axle diesel-electric freight locomotive developed in part from the , for use on the railways of the UK. Since its introduction the class has been successful and has been sold to British and other European railway companies. In Continental Europe it is marketed as the EMD Class 66 (JT42CWR). History Background On the privatisation of British Rail's freight operations in 1996, Wisconsin Central Transportation Systems under the control of Ed Burkhardt bought a number of the newly privatised rail freight companies: Transrail Freight, Mainline Freight, Loadhaul, and later, Railfreight Distribution and Rail Express Systems; thus controlling 93% of UK rail freight. After a public relations exercise involving the input of the general public, the company was named English Welsh & Scottish Railway (EWS). EWS inherited a fleet of 1,600, mainly diesel, locomotives, with an average age of over 30 years; 300 had been cannibalised for spares. Typical of the fle ...
