Vienna EcoTram
Vienna public transport operator 4203 Wiener Linien is testing an energy saving tram, the EcoTram, using it in daily operation until May 2014. The tram is part of a bigger project to make public transport vehicles more energy efficient.

A 189 Siemens ultra low floor tram has been equipped with intelligent control units that predict whether cooling or heating will be required. If the tram enters a tunnel where the ambient temperature is cooler, the air-conditioning will be turned down. The units control three air-conditioning units with heat pumps, a variable-frequency compressor and CO2 sensors. According to Siemens, the tram could offer annual savings of up to 3,000 MWh for tram operator Wiener Linien.

The EcoTram project has been running since 2009, supported by the Climate and Energy Fund of the Austrian Research Promotion Agency as part of its New Energies 2020 programme.

Other project partners include the Automation and Control Institute at Technische Universität Wien, which has developed the control software; Rail Tec Arsenal, which has manufactured the measuring technology; and Vossloh Kiepe, which has supplied the heating and air-conditioning units. Consulting firm SCHIG mbH is the project manager.

Market experts believe that rapidly falling battery costs – which make up about one third of the costs of an electric car – and growing

    When Atlanta’s streetcar project had some issues, Siemens helped to solve them – but started out by just listening, says Chris Maynard, the company’s head of rail services. It’s funny how often niggling problems can be a warning sign that there are bigger issues requiring attention – and not so funny how things can escalate if you don’t pay attention to them. With that in mind, Siemens was hired as service provider for the Atlanta Streetcar system - four vehicles operating on a two-mile loop in downtown

This gave David Arminas a chance to assess how fast Motor City is moving down the road to recovery. Motor City, as Detroit is still called, was on its financial knees only five short years ago. The future looked bleak as the city and greater urban area bled jobs and population. It was on 18 July 2013 that Motown, as Detroit is also known, filed for Chapter 9 bankruptcy protection, the

    Grand plans have been announced for transport investment in India aimed at boosting city economies. India’s Government Secretary for Urban Development Sudhir Krishna explains all to Jason Barnes. There are many reasons for developed countries’ high levels of urbanisation, not least of which is that the types of employment to be found in towns and cities tend to generate relatively greater wealth and so make greater contributions to a country’s economy. That creates the imperative for developing nations to f
