Eminox retrofit technology helps reduce diesel particulate matter from the rail network, delivering environmental benefits to communities served by the railways. The partnership 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. The project could help achieve SWR’s target of a 56% reduction in traction carbon emissions by 2023/24.
Porterbrook’s investment in the Eminox technology is supported by the Department for Transport through InnovateUK’s first-of-a-kind funding – FoaK2. The funding enables the trial fitment of Eminox SCRT® technology to an SWR Class 159 diesel multiple unit. Once the trial is completed, the innovation is likely to be deployed across a number of existing fleets.
State-of-the-art telemetry will be fitted to the trial Class 159 to provide real-time diagnostics and performance data. This first on-rail application incorporates solving rail-specific challenges, such as overcoming high exhaust temperature duty cycles, drawing on proven technologies from other sectors.
The project is part of the government’s drive towards a cleaner, greener economy by cutting emissions and removing diesel-only trains from the network by 2040.
Mary Grant, CEO of Porterbrook, said: “Porterbrook believes by partnering with Eminox, we can accelerate the delivery of cleaner and more environmentally friendly trains to Britain’s railways.”
