The Guardian are quoting a TfL source as saying
"the incident happened inside a tunnel" -

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'
