SWR And Porterbrook Trial New Emission-Slashing Rail Technology

The title of this post is the same as that as this article on Rail Technology Magazine.

This is the first three paragraphs of the article.

Groundbreaking emission-reducing technology is to be fitted to South Western Railway (SWR) train units as part of a new trial aiming to cut down harmful emissions from diesel trains by 80%.

Porterbrook is working in partnership with exhaust manufacturer Eminox to carry out the trial, with the DfT supporting the rolling stock company’s investment.

This will see South Western Railway’s Class 159 diesel units fitted with a first-of-its-kind emissions control device, with plans to roll out the technology to hundreds of diesel trains across the UK’s rail network.

I have looked up Eminox on their web site.

This is the mission statement on the front page.

Eminox designs and manufactures exhaust after-treatment systems, reducing emissions from heavy-duty vehicles and equipment.

Our products are supplied as original equipment to meet the latest emissions standards. We also produce complete emissions systems for retrofit to meet the ever-changing demands of local air quality programmes such as London’s Ultra Low Emission Zone and Clean Air Zones across the country.

Our Eminox Custom team specialises in exhaust conversions and bespoke systems.

While politicians dither and fiddle, engineers engineer, with a little bot of help from Porterbrook and the DfT.

If this technology proves to be successful, I can see its application to large numbers of diesel trains around the world.

  1. Eminox have been around for decades! Though before all the emission reduction stuff was a thing, they simply made exhaust systems for heavy vehicles. In fact, they made the original 158/159 exhaust systems!

    • Thanks! It probably shows how stupid some organisations and compabies are about ideas that would improve what they do!

  2. I would have thought a fleet of hybrid trains running off 3rd rail DC from Waterloo to limits of electrification and the diesel electric to end of routes with potential for AC addition if electrification is extended would be a better solution.

    Wonder if there are any more spare ex class 319 trains converted to hybrid operation that SWR could deploy ?

    • I don’t feel that the Class 769 trains would be ideal for the long routes from Waterloo where Class 158/159 trains are deployed.

      This technology cleans them up, but is only an interim solution.

      The long term solution for Waterloo-Exeter is Bombardier’s proposed 125 mph bi-mode Aventra, which could end up on the Midland Main Line and with Cross Country.

      For the routes in the Southampton area, which are run by 158s, I suspect battery trains like Porterbrook’s version of the Class 350 will be the solution.

      But there are also a lot of 158s with Northern and ScotRail, that need cleaning up.
