Were any of the Gottardo 2016 sponsors such as ABB in attendance at your event with all or part of their June 5 & 5 exhibits? I found them very interesting.
BTW, a friend of mine who lives in Greifensee found a white Roco Gottardo 460 locomotive for me at a model train store in Rapperswil. These are very rare now as I assume thousands of Swiss wanted them as souvenirs.
