I saw at least one Freccio Argento ETR 610 with yellow UIC numbers which were 93 85 X 610... I also saw at least two trainsets which did not have these larger numbers on the coach sides. I saw at least one SBB unit which had CH-SBB and I-TI markings. The other SBB units had 93 85 5 numbering but were not class 610. May have been RABe 503 (2nd series)
