TfL has published a new report which says it is considering "upgrading its CCTV system", although it is not clear whether this relates to cameras on the trams themselves.
It is also considering using technology already in place on buses, such as software called iBus, to monitor speeds and locations of trams.
It is also looking at installing an in-cab, "driver-alert system", additional lineside digital signs to warn drivers of the speed limits and chevron signs at four sites with significant bends.
The report, due to go to TfL's safety, sustainability and human resources panel next week, says TfL has been working with FirstGroup, which operates the trams as a contractor, to monitor its "enhanced driver management arrangements".
It reveals that since the crash there have been more frequent speed checks, briefings on fatigue management, accompanied driving through the area of the derailment if requested and counselling.
