The vienna subway sign has its origins in the "Wiener Würfeluhr" - translated: vienna boxclock ;-). One of the accompanying photos showing the original clock, other the original places of the Subway Sign. This signs are located at all underground stations in Vienna.I would like to thank SoJiro for his wonderful idea to make this sign for Cities Skylines. His asset was the direct model. Thanks to him for this great preparatory work.In gratitude for SiJiro I have set the subway sign right next to his Vienna Metro Station U3. These two assets constitute a typical Viennese situation, the combination of both elements.This underground sign is semiscale, the same size as in reality.The asset can be found after installation under underground buildings. I hope you have fun with it.
