Siemens ACS-64
The Siemens ACS-64, or Amtrak Cities Sprinter, is an electric locomotive designed by Siemens Mobility for use on the Northeast Corridor (NEC) and the Keystone Corridor in the northeastern United States. The design was based on locomotives Siemens created for use in Europe and Asia, but with changes to comply with American standards. The ACS-64 is built at the Siemens factory in Florin, California, located outside of Sacramento. The first 70 locomotives were built for Amtrak to replace the railroad's fleet of aging AEM-7 and unreliable HHP-8 locomotives. The first ACS-64 entered service in February 2014 and deliveries continued until August 2016. The Southeastern Pennsylvania Transportation Authority (SEPTA), in Southeastern Pennsylvania, operates a fleet of 15 ACS-64s since August 2018, on the agency's Regional Rail Lines. Design The design is based on the EuroSprinter and the Vectron platforms, which Siemens sells in Europe and Asia. Significant structural changes to t ...

Crescent (train)
The ''Crescent'' is a daily long-distance passenger train operated by Amtrak between New York City and New Orleans (the "Crescent City"). The route connects the Northeast to the Gulf Coast via the Appalachian Piedmont, with major stops in Charlotte, North Carolina; Atlanta, Georgia; and Birmingham, Alabama. Most of the route of the ''Crescent'' is on the Norfolk Southern Railway. It is the successor of the ''Southern Crescent'', introduced in 1970 by Norfolk Southern's predecessor, the Southern Railway. History ''Southerner'' Today's ''Crescent'' is a direct descendant of the '' Southerner'', a streamlined passenger train operated by the Southern Railway from 1941 to 1970. The daily train followed essentially the same route as the modern ''Crescent'', providing sleeper service between New York and New Orleans via Washington, Atlanta, and Birmingham. ''Southern Crescent'' Since its inception, the sister train of the ''Southerner'' was a second New York–New Orleans sl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a Battery (electricity), battery or a supercapacitor. Locomotives with on-board fuelled prime mover (locomotive), prime movers, such as diesel engines or gas turbines, are classed as Diesel–electric powertrain, diesel–electric or turbine–electric powertrain, gas turbine–electric and not as electric locomotives, because the electric generator/motor combination serves only as a Transmission (mechanics), power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric loco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monocoque
Monocoque ( ), also called structural skin, is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word ''monocoque'' is a French term for "single shell". First used for boats, a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames. By contrast, a semi-monocoque is a hybrid combining a tensile stressed skin and a compressive structure made up of longerons and ribs or frames. Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies, which tend to be composites, and inflatable shells or balloon tanks, both of whi ...

Crashworthiness
Crashworthiness is the ability of a structure to protect its occupants during an impact. This is commonly tested when investigating the safety of aircraft and vehicles. Different criteria are used to figure out how safe a structure is in a crash, depending on the type of impact and the vehicle involved. Crashworthiness may be assessed either prospectively, using computer models (e.g., RADIOSS, LS-DYNA, PAM-CRASH, MSC Dytran, MADYMO) or experiments, or retrospectively, by analyzing crash outcomes. Several criteria are used to assess crashworthiness prospectively, including the deformation patterns of the vehicle structure, the acceleration experienced by the vehicle during an impact, and the probability of injury predicted by human body models. Injury probability is defined using criteria, which are mechanical parameters (e.g., force, acceleration, or deformation) that correlate with injury risk. A common injury criterion is the head impact criterion (HIC). Crashworthiness is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vectron (locomotive)
The Vectron is a locomotive series made by Siemens Mobility, introduced at the 2010 InnoTrans trade fair in four prototype versions: diesel, multi-system, and both AC and DC electric power. The diesel version has been replaced in 2018 by a dual mode locomotive which is powered by electricity on electrified sections of the track and can be switched to diesel mode on non-electrified sections. The Vectron series is reconfigurable and modular, with a Bo'Bo' wheel arrangement, and is intended as the successor to the EuroSprinter family of locomotives. It can be configured to use any or all of the four electric power systems commonly used in Europe. A more affordable, basic version called Smartron was introduced in 2018. Background and design Around the end of the 20th century and the beginning of the 21st century Siemens successfully produced freight and passenger/universal versions of its EuroSprinter locomotive platform; initially made as single voltage machines for European stat ...

EuroSprinter
The EuroSprinter family of electric locomotives is a modular concept of locomotives for the European market built by Siemens Mobility. The internal Siemens product name is ES 64, with ES for EuroSprinter and the number 64 indicating the 6,400 kW power at rail. Additional information is given in the name on the usage (U as universal, P as prototype and F as freight) and on the number of electric power systems supported (e. g. 2 as two types, 4 as all four systems commonly used in Europe). Development The first prototype ES 64 P was built in 1992, as Deutsche Bahn AG was expected to issue a large order of locomotives as a replacement for the ageing Einheits-Elektrolokomotiven. The external appearance was similar to the earlier Siemens/Krauss-Maffei made dual voltage Spanish RENFE Class 252, delivered in 1991, which in turn used three phase asynchronous drive technology introduced with the DB Class 120. The prototype was used for extensive tests in some countries in Europe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bombardier–Alstom HHP-8
The Bombardier–Alstom HHP-8 (''High Horse Power 8000'') is a twin-cab electric locomotive built for Amtrak and MARC by a consortium of Bombardier and Alstom. Its electrical system was based on Alstom's BB 36000 locomotive. Due to a limited number of locomotives produced and reliability issues leading to high maintenance costs, Amtrak retired all its HHP-8s after only 10 years of service. MARC initially planned to follow suit but ultimately chose to refurbish their HHP-8 fleet between 2017 and 2018. Background Amtrak assumed control of almost all private sector intercity passenger rail service in the United States on May 1, 1971. The centerpiece of Amtrak's system was the Northeast Corridor, a line between Washington, D.C., and Boston, Massachusetts, via New York City. The line was electrified from Washington through New York to New Haven, Connecticut; diesel locomotives handled trains over the remaining between New Haven and Boston. In the 1990s Amtrak rebuilt and electri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD AEM-7
The EMD AEM-7 is a twin-cab four-axle AAR wheel arrangement#B-B, B-B electric locomotive manufactured by Electro-Motive Diesel, Electro-Motive Division (EMD) and ASEA between 1978 and 1988. The locomotive is a derivative of the Swedish SJ Rc4 designed for passenger service in the United States. The primary customer was Amtrak, which bought 54 for use on the Northeast Corridor and Keystone Corridor. Two commuter operators, MARC Train, MARC and SEPTA, also purchased locomotives, for a total of 65. Amtrak ordered the AEM-7 after the failure of the GE E60 locomotive. The first locomotives entered service in 1980 and were an immediate success, ending a decade of uncertainty on the Northeast Corridor. In the late 1990s, Amtrak rebuilt 29 of its locomotives from DC to AC traction. The locomotives continued operating through the arrival of the final Siemens ACS-64 in June 2016. MARC retired its fleet in April 2017 in favor of Siemens Chargers, and SEPTA retired all seven of its AEM-7s i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
