Linz Linien, the transportation company of the City of Linz, and Bombardier Transportation have been cooperation partners since 1999. As from that time, a total of 60 tram trains had been ordered, and most of them have already been delivered. In recent years, the cooperation has been supplemented by the conclusion of a tram vehicle maintenance contract. Source

We present an approach to high-resolution rail surface analysis combining 2D image texture classification and 2 1/2 D analysis of surface disruptions. Detailed analysis of images of rail surfaces is used to observe the condition of rails and, as a precaution, to avoid rail breaks and further damage. Single rails are observed by a color line scan camera at high resolution of approximately 0.2 millimeters and under special illumination in order to enable 2 1/2 D image analysis. Gabor filter banks are used for 2D texture description and classes are modeled by Gaussian mixtures. A Bayesian classifier, which also incorporates background knowledge, is used to differentiate between surface texture classes. Classes which can be related to surface disruptions are derived from the analysis of the anti-correlation properties between two color channels. Images are illuminated by two light sources mounted at different position and operating at different wavelengths. Results for data gathered in the Vienna metro system are presented. © 2010 Springer-Verlag. Source

The Security Commission is conducting a survey among its members on security policy, measures and motivation in their networks. Despite the wide variety in geographical locations, size and nature of the participating networks, some valuable conclusions can be drawn from the results. Source

The Viennese like their public transport system. 37% of all journeys in the Austrian capital are made on metro, trams and buses, putting Vienna in a top position internationally. Reliable operations, intelligent infrastructure and modern vehicles are all central to passenger satisfaction. But that is not all: good information, in particular, and authentic external communication are vital elements underpinning the company's popularity with passengers. Passenger satisfaction surveys have shown that 95% of respondents rate the service provided by Wiener Linien as 'good'; a percentage that is on the rise. This is the result of our ongoing efforts to find new ways of improving our services but also of continuing to increase passenger satisfaction in the future. Source

This article calculates the impact of three measures in order to reduce the global warming potential (GWP) and cumulative energy demand (CED) of Vienna's subway line U2. Results show that the increase of the train occupancy rate has the highest reduction impact (–30%/–30%), followed by new rolling stock (–26%/–34%), and a change in energy mix (–8%/–4%). The total reduction to be achieved with all measures combined is around –55% for GWP and CED, leading to a GWP of 91 [g] and 1.653 [MJ] per passenger kilometer traveled (PKT). With all these measures applied, the subway has lower GWP and CED than other modes of transport presented in the literature. © 2016 Taylor & Francis Group, LLC. Source
