On my recent trip to Switzerland, I observed a Trenitalia ETR 610 in Zurich HB with Swiss UIC numbering. How many of the FS trainsets are registered in Switzerland? I know that the ETR 470s were at one point registered to Cisalpino AG Bern. Is this because a few of the original ETR 610 were also delivered to Cisalpino AG? I thought that they had reverted to either SBB or TI?
