All trains are timed at 321 running times regardless of whether they are Class 321s or Class 360s which is why there aren't any differences. If some trains were timed at Class 360 running times you would have to account for the longer dwell times in timing the trains from origin to destination. This would would lead to differences in journey times between one hour and the next for the same journey - eg 1Y35 could have a different journey time to 1Y37 in the next hour accounting for traction type. Hence why you can't see it just looking at the data as provided on sites like Realtime trains.
