TRB Lightweight Structures is to design and manufacture a unique emergency detrainment system in partnership with Siemens Mobility for 94 nine-car ‘Inspiro’ train sets for the London Underground Piccadilly Line. These state-of-the-art trains will replace outdated rolling stock that entered service in the 1970s, and will be fully assembled in the UK.

TRB, based in Huntingdon, has been selected to design and manufacture a unique emergency detrainment system to meet the stringent requirements and specifications of the new fleet, including GMRT 2100 fire and impact tests. The emergency detrainment systems include M Door, bridge and stairs.

The contract – with potential for follow-on orders – was awarded to TRB thanks to its position as a global leader in the manufacture and design of high-quality rail interiors, door leaves and detrainment systems. Almost a fifth of TRB’s 130+ strong workforce will be occupied in delivering 188 complete systems (two per train) for this project, with the first train sets due for completion in February 2022.

Toni Shepherd, director of Sales at TRB, commented: “We have over 40 years of experience in the design and manufacture of high-quality components for the rail industry, and have manufactured the majority of the UK’s detrainment systems currently employed on UK rolling stock. Our production methods include comprehensive in-house testing, from load to simulated evacuation tests. We are delighted to have been chosen to be involved in this exciting new partnership with Siemens Mobility, which further highlights our expertise in the sector, and is excited for the opportunities that come with it.”
