This is from Jan-2019. I reckon it's a given.

'Recommendation 4:UK tram operators, owners and infrastructure managers should work together to research and evaluate systems capable of reliably detecting driver attention state and initiating appropriate automatic responses if a low level of alertness is identified. Suchresponses might include an alarm to alert the tram driver and/or the application of the tram brakes. This recommendation was addressed using available technology in October 2017. Working with Trams Operated Limited (TOL), TfL implemented a Driver Protection Device (manufactured by Seeing Machines). Also known as ‘Guardian’, this device uses advanced sensors and image processing technology to track the micro-movements of the driver’s eyes, facial expressions and head to identify fatigue and distraction events. When an event is detected, the driver receives an immediate in-cab audible alarm and in the case of fatigue events, a physical seat vibration alert designed to restore the driver to an alert state.London Trams and TOL are the first public transport owner/ operator team to implement the Guardian device on trams. This device has been commended by the ORR and has been shared and demonstrated to the UK Tram industry for possible implementation on other tram networks.This system is designed to detect driver inattentiveness and provide an alert, but does not, itself, apply the brakes, as suggested as an option in the recommendation.As detailed in recommendation three, an automaticbraking systemhas been procured and will be installed by the end of 2019 as a separate measure.Research work being undertaken by UK Trams is exploring what an appropriate automatic responsewould beif a low level of driver attentiveness is detected, such as the application of brakes. TfL will review this research to ensure the system in use is compatible with the outcomes'
