The order was placed in 2017 at igm Robotersysteme AG to replace the first plant at the operation station “Wasserleitungswiese” of Wiener Linien, which has been in operation since 1988. At that time, two longitudinal carriages were implemented on each side for cleaning a single set (double railcar) of the Viennese subway of type U. The new igm robot installation is also suitable for type V (a continuous permanently coupled six-carriage train, divided into 3 parts for cleaning) and consists of one longitudinal carriage way on each side in a special slim design with a travel distance of 27 m. In addition, there is the 2-stage dust exhaust system as well as light barriers and doors with safety limit switches for access protection.
