I've recently started a daily commute from Sandy to Finsbury Park (then onwards to Moorgate). The train I would normally catch is the 7.02am from Sandy, which is the 6.32am from Peterborough. Is there any way of finding out which unit is allocated to that service each day? The realtimetrains website always suggests it's a 365, but more often than not, it turns out to be a 321. The only reason I'm asking is that the 321 seems to be incapable of keeping to the timetable, and always end up late by the time they reach London... the 365 has no such trouble. Thanks.
