They’re starting at Cornbrook. Even if they were starting at Pomona they can’t turn back there.I'm not sure that the timings have been announced yet but typically trams start at around 6.30am on a Sunday - if you do want to be first on the tram then I'd keep an eye on publicity this week. I'd also check whether the trams are starting at Pomona or in fact at Cornbrook - I've seen press suggesting both and if you check out the Metrolink website it shows the new line starting at Cornbrook.
