Managing driver fatigue could be one of the main issues raised when the group investigating the Croydon tram crash releases its final report.
Seven people were killed and 51 were injured when a tram came off the tracks, overturned and slid for 25 metres shortly after 6am on November 9 2016.
The Rail Accident Investigation Branch (RAIB) has said that the way tiredness is managed by London tram operator FirstGroup may feature in a section of a final report aimed at preventing similar accidents occurring,
The final report is "nearing completion" and is expected to be published by the end of the year.
The RAIB said other recommendations likely to be featured in the document include:
Introduction of a system to prevent serious accidents due to excessive speed at high-risk locations
Researching how the attention state of drivers can be detected
Improving containment of passengers by tram windows and doors
Creation of an industry body to facilitate more effective cooperation between tram networks and operators on safety issues
An interim report found the two-carriage tram was travelling at 46mph as it entered a sharp bend at Sandilands Junction, Croydon, which had a 13mph limit.
The late application of the brakes, and the absence of emergency braking, suggests the driver "lost awareness", according to RAIB.
