Them trams can pick up a bit of speed especially downhill, that corner is basically the shape of an "L" upside down on a downhill bend. I remember back when I use to catch tram on a regular people/shopping would be sent flying on that corner certain times.
Weather didn't play no part in that, Tramlink been going around that corner for 16 years in worse weather, that's down to driver error or mechanical
