Ceneri Base Tunnel 460s?


Excuse the question, but does anyone know of trains that pass through the Ceneri Base Tunnel that are booked for class 460 please?

Before travelling I did some research and couldn't find any. During the day on Saturday 14 August all I saw was 500s, 501s, 502s and 524s. So I was somewhat surprised when heading north to pass 460 039 on 17:05 Z├╝rich Hbf-Lugano(IC881). On checking reisezeuge.ch, I saw that this train should have been a class 500.
