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.

Comparing Class 195 And Class 769 Trains

This may seen a strange comparison to do.

  • In the blue corner is an upgraded forty-year-old four-car bi-mode Class 769 train from British Rail via Brush at Louthborough.
  • In the red corner is a new three-car diesel Class 195 train from CAF.

So how do they compare?

Seats

  • The Class 769 train shows 255 Standard Class and 12 First Seats in an example layout in the brochure.
  • The Class 195 train has 204 seats according to Wikipedia.

The seats per car in both trains are almost identical.

Diesel Power

  • The Class 769 train has two 390 kW diesel engines and electric transmission.
  • The Class 195 train has three 390 kW diesel engines and a ZF Ecolife six-speed transmission.

So it would appear that the Class 195 train is more powerful, but Class 769 train has an electric transmission, which doesn’t need to change gear.

I look forward to riding in both trains.

Operating Speed

  • The Class 769 train has a 100 mph operating speed on electricity and has been designed for 91 mph on diesel power.
  • The Class 195 train has a 100 mph operating speed.

The proof of the pudding will be in the timetables and journey times.

Conclusion

The two trains are fairly evenly matched for a lot of routes.
