Porterbrook, headquartered in Derby, is trialling emissions-reducing technology which could be rolled out to hundreds of diesel trains across the UK’s rail network.

The partnership between Porterbrook, the rolling stock asset management company and Eminox, the exhaust manufacturer, aims to reduce diesel emissions by fitting a catalyst that could reduce NOx (nitrous oxide) emissions by over 80% and CO (carbon monoxide) and hydrocarbons by over 90% from current levels.

Porterbrook’s investment in Eminox’s technology is being supported by the Department for Transport through InnovateUK’s first-of-a-kind funding (‘FoaK2’).

The Foak2 funding will allow trial fitment of Eminox SCRT® technology to a South Western Railway (‘SWR’) Class 159 diesel multiple unit. Once the trial is completed this innovation is likely to be deployed on a number of existing fleets serving communities across Britain’s railway.

Mary Grant, CEO of Porterbrook, said: “As a rolling stock asset management business, Porterbrook takes seriously its responsibility to develop innovative ways of reducing emissions. We are particularly pleased to be able to do this by drawing on proven technologies from other sectors.

“Porterbrook believes by partnering with automotive after-treatment specialists, Eminox, we can accelerate the delivery of cleaner and more environmentally friendly trains to Britain’s railways.”
