After completion by the manufacturer, VAE Eisenbahnsysteme GmbH, located in Zeltweg, the equipment was initially loaded onto three trucks and transportet by heavy load to Schwechat Airport. At the airport, the switch components were loaded into an airplane provided by Metro Tehran. The group of switches consists of three sets of points with a total weight of 50 tons. To speed up installation, core parts of the switches were supplied pre-assembled. The socalled switch blade operating devices – partially pre-installed on sleepers – have a total length of almost 28 metres and are supplied as one single part. ‘For many decades, the Iranian customers have been appreciative of the high quality and the excellent technology of our switches. This forms the basis for our relationships with these customers, which are important to us and which have been built up over many years’, commented Marc Kaddoura, Managing Director of VAE GmbH.
