The Rail Accident Investigation Branch has said: "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."
Elsewhere in London, commuters are facing a third, and possibly fourth, day of delays on Thameslink and East Midlands Trains services due to signalling problems.
