The software control SCADA system for the Gotthard Base Tunnel is called WinCC OA, made by ETM Siemens. Full disclosure: I did a summer job for them in Eisenstadt, Austria in 2012, and my dad uses the same software at CERN. ETM made software called PVSS, and it was renamed to WinCC OA when ETM got bought by Siemens. The previous Siemens software, WinCC, was the victim of the Stuxnet worm. Hopefully ETM's is a bit more secure!
