Siemens Mobility

Siemens Mobility is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Siemens Mobility rather than just read about it. In short: Siemens Mobility GmbH is a division in Siemens of Germany that specializes in rail transport. With its global headquarters in Munich, Siemens Mobility has four core business units: Mobility Management, dedicated to rail technology and intelligent traffic systems, Railway Electrification, Rolling Stock, and Customer Services.

Key takeaways

Siemens Mobility belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Siemens Mobility to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Siemens Mobility from memory before moving on to harder problems.

Reference excerpt

Siemens Mobility GmbH is a division in Siemens of Germany that specializes in rail transport. With its global headquarters in Munich, Siemens Mobility has four core business units: Mobility Management, dedicated to rail technology and intelligent traffic systems, Railway Electrification, Rolling Stock, and Customer Services.

History Innovations from the late 19th century, such as the world's first electric train, when Siemens & Halske unveiled a train in which power was supplied through the rails, and the world's first electric tram, with the implementation of 2.5-kilometer-long electric tramway located in Berlin, built at the company's own expense, cemented the use of electric power in transportation systems. In the following years, inventions such as the first electric trolleybus, mine locomotives, and the first underground railway in continental Europe (in Budapest), set the path from trams and subways to today's high-speed trains. In 1991, Siemens acquired a 60% shareholding in Duewag. In 1999, Siemens increased its stake in KraussMaffei from 25% to 75%. Siemens, alongside ThyssenKrupp and Transrapid International, was part of the German consortium that built the Shanghai Maglev, inaugurated in 2002 by the German chancellor, Gerhard Schröder, and the Chinese premier, Zhu Rongji. It was the world's first commercial high-speed magnetic levitation train, which holds the title of the fastest commercial service, travelling up to 430 km/h. In November 2012, Siemens acquired Invensys Rail for £1.7 billion. In July 2017, Siemens confirmed it had taken over Hannover-based software company HaCon, to be managed as a separate legal entity. The financial details were not disclosed. In September 2017, Siemens announced a proposal to merge its transportation division with Alstom, with the objective of creating "a new European champion in the rail industry". The combined rail business, to be named Siemens Alstom and headquartered in Paris, would have had $18 billion U.S. in revenue and employed 62,300 people in more than 60 countries. It was seen as a measure to counter the rise of China's CRRC with support from both the French and German governments. However, in February 2019, the European Commission refused permission for the merger to proceed. During Innotrans in September 2018, Siemens Mobility unveiled the world's first driverless tram in Berlin, the result of a joint research and development project with ViP Verkehrsbetriebe Potsdam, on a six-kilometre section of the tram network in Potsdam, Germany.

Worked examples

Example 1 — a first encounter with Siemens Mobility

Start with the simplest possible case. Write down what Siemens Mobility claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Siemens Mobility before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Siemens Mobility ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Siemens Mobility

In research: Siemens Mobility appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Siemens Mobility in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Siemens Mobility is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies based in Berlin, Rail infrastructure manufacturers, Railway signalling manufacturers, so understanding it makes those chapters shorter.
In everyday life: Look for Siemens Mobility outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
