Vienna tests energy saving tram

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.

    ASFINAG has developed a mobile traffic monitoring and guidance system through a pre-commercial procurement project. Drivers have become accustomed to roadside and gantry-mounted traffic guidance and control systems along the major roads and main motorway sections. But there are occasions when intense monitoring is required on a temporary basis along motorway sections without traffic guidance and control systems and on federal and national roads too. Examples include the monitoring of the traffic flow during

    New analysis by plug-in vehicle campaign Go Ultra Low suggests that British motorists could no longer have to rely on the conventional petrol station. More than 90 per cent of electric vehicle (EV) charging takes place at home while total charging volumes have almost tripled since 2014, according to new usage data from leading infrastructure provider Chargemaster. Coupled with bumper uptake of plug-in vehicles – more than 14,500 were registered in the first half of 2015 – the new findings point to the po
