Which suggests it was running north towards Sandilands Station and
something had happened inside the tunnel.

Frustrating that there's no definite reporting of its direction.

Daily Mail now reporting:

'It happened on a sharp bend on the approach to Sandilands tram stop.'

Which is consistent with another comment:

'As we looked down on the tram it was on its right hand side'

From Sandilands the track descends steeply and splits in two, where it joins the route of the former Woodside and South Croydon Railway. By the look of the overhead shot, it was possibly taking the righthand track and came off. Or was it coming the other way and took the corner too fast? If it wasn't human error, then perhaps brake failure? I'm not familiar with braking systems on that system.

Electric, combined with electromagnetic, AFAIK.

Which isn't "approching Sandilands"

and splits in two, where it joins the route of the former Woodside and
South Croydon Railway. By the look of the overhead shot, it was
possibly taking the righthand track and came off.

Which would leave it rolled over on its *left* side.

From RAIBC:

"The tram was operating an 'inbound' service from New Addington to Wimbledon
via Croydon town centre. Sandilands Junction is the point where inbound
trams from the Beckenham Junction/Elmers End and New Addington routes
converge, shortly before they arrive at Sandilands tram stop (to the east of
Croydon town centre). Trams approaching from the New Addington direction
have to negotiate a sharp, left-hand curve with a speed limit of 20 km/h (12
mph) before reaching the junction. The derailment occurred on the curve and
initial indications suggest that the tram was travelling at a significantly
higher speed than is permitted."

It seems to have come to rest inside the overhead line support for the righthand track, but on it's righthand side. Given that if it was going left, it would have been on the lefthand side and going right would have needed to traverse the points of what looks like a single slip at the junction, it must have derailed either at the points or been going too fast. Another possibility is it could have been coming the other way, from the lefthand track, derailed at the points and slid back down the slope, overturning when it hit the split in the track direction. Can't see that one myself though.

Trams are essentially road vehicles that happen to run on rails -
safety standards are by and large similar.

Maybe he wasn't asleep but listening to the news and
fainted when he heard the American election results...?
