UK’s first automatic braking system for trams to be installed by the end of 2019

The system will automatically apply the brakes and bring a moving tram to a controlled stop if the vehicle exceeds the speed limit at designated locations.

London’s tram network will be the first in the UK to have an automatic braking system due to TfL’s decision to award a contract to Engineering Support Group Limited (ESG).

The contract contains the agreement that ESG will build and install the new safety system by the end of 2019, including a period of training and familiarisation with tram drivers.

Work began on the feasibility of introducing this safety measure, which has not been introduced on any UK trams before, shortly after the overturning at Sandilands, Croydon, in November 2016. It will operate alongside the driver protection device that has been in operation since September 2017, alerting to any signs of driver distraction and fatigue.

Automatic braking is one of the recommendations set out by the Rail Accidents Investigation Branch (RAIB) following the overturning incident. It will initially be configured to priority high-risk locations as suggested by the RAIB but will have the flexibility to be introduced elsewhere on the tram network.

The RAIB listed 15 recommendations aimed at the UK tram industry. Work has progressed on all of the recommendations specific to TfL with some of the most vital already complete. These include a permanent speed reduction across the tram network, speed monitoring and signage at significant bends, and an enhanced customer complaints process.

A new emergency lighting system, which will operate independently of the tram’s battery in the event of an emergency, has also been procured and will be installed over the summer of 2019, addressing recommendation seven. Extensive testing with safety experts has also progressed and a new higher specification film that is 75 per cent thicker (from 100microns to 175microns) will be fitted to all doors and windows to improve containment, as per recommendation six, by spring.

Mark Davis, TfL’s General Manager of London Trams, said: “We will never forget the tragedy at Sandilands and have focused our attention on preventing this type of incident from ever happening again. Awarding the contract for a new automatic braking system is a first for trams in the UK, and not only will it improve safety for customers in London, but we hope it will lead the way for other tram operators across the country. We will work to have the new system, which will automatically apply the brakes if a tram is exceeding the speed limit, in full operation by the end of 2019.”
