Before services resumed, and in accordance with advice in the Rail Accident Investigation Branch's (RAIB) interim report into the derailment, additional speed restrictions and associated signage have been introduced near Sandilands.
These precautionary measures have also been implemented at three other locations on the tram network.
All tram drivers were fully briefed prior to resumption and additional staff from TfL and FirstGroup will be available across the network to provide support and information for customers and employees. FirstGroup will also be carrying out enhanced speed monitoring across the tram network.
Engineers have repaired all track and other equipment and have run trams over the repaired section. We have carried out a thorough safety assessment and taken the advice of an independent panel of tram experts as part of a rigorous safety assurance process before resuming the service.
Support is being offered to the families of those who lost their lives or who were injured. This includes the services of our Sarah Hope line, which offers practical, financial and other support.
Mike Brown MVO, London's Transport Commissioner, said: 'Our thoughts are with everyone affected by what happened last Wednesday, and we are doing everything we can to ensure that they receive support at this incredibly difficult time.
'Following the RAIB's interim investigation, we have implemented their advice on additional speed restrictions and signage and carried out a rigorous safety assessment prior to restoring services earlier today.'
