The Elizabeth Line Light box

London, England

The Elizabeth Line Light box was created by Designplan for the Crossrail project, now known as the Elizabeth Line which is an accessible route of 40 stations from Reading and Heathrow in the west to Shenfield and Abbey Wood in the east.

Designplan were asked to look at the platform lighting in 2013. “The architect had a specific vision of how the platforms should be lit” says James Coma, Project Manager at Designplan Lighting. ”To achieve this, we designed The Elizabeth Line light box to illuminate the platform edges”.

“Many considerations had to be taken into account by Designplan for a project of this scale” says James. “This includes accessibility and the requirement for architecturally pleasing lighting”.

The Elizabeth Line light box is 1.5 metre wide by 1 metre high, weighing about 90 kilos with a design life of 30 years. They produce an output of over 6,000 lumens, whilst consuming the energy of a 60 watt household lamp!

Approximately 150 light boxes are required for a platform. Therefore a key consideration was to make maintenance quick and hassle free.

“For easy maintenance we designed a hinged LED array system to provide access from below” explains James. “Using LEDs also provides significant energy savings, as they last up to five times longer than traditional fluorescent lamps, reducing the overall cost of ownership”.

“The regulations affecting all luminaires specified, are contained in a document practically an inch thick” explains James. “Accordingly, all our Elizabeth Line light boxes are designed in accordance with the Fire Precautions (Subsurface Railway Stations – England) Regulations 2009, commonly known as section 12, and comply with London Underground’s subsurface standard 1-085.

The Elizabeth Line light boxes were rigorously blast and fire tested, assessed for electro-magnetic field interference and impact, ingress and safety tested”. In addition, our removable gear trays enable easy adoption of upgrades in technology, further extending the life and performance of our luminaires.

“Having our manufacturing facility and design team on site enabled us to adapt to the needs of the Crossrail project” explains James.

“For example, we collaboratively developed the brackets for the Elizabeth Line light boxes as well as a method for mounting them. This was tested at our factory to ensure ease of installation prior to being installed on site.”

In addition, a new production line was created and a reusable metal packaging system was designed for securely delivering the light boxes and minimising waste”.

Post opening

The Elizabeth Line was officially opened on the 24th May 2022, making the commute for millions of passengers easier with quicker journey times. James reflects, “Being able to see and enjoy the final project makes all the hard work worth it. Since the opening, I have travelled many times on the new line, and it is safe to say it has made my life much easier. I am very proud that I was involved in such an incredible manufacturing and engineering project. Congratulations to everyone who was involved.”
