Sulnox Group has announced that Colas Rail UK will use the company’s Sulnox Eco fuel conditioner across its fleet.
It follows the successful evaluation of the fuel conditioner for use in diesel-powered tampers and locomotives. This sees over 10 million litres of diesel used by Colas Rail UK annually.
"Cutting emissions is vital for rail's future, and these trials prove that Sulnox Eco delivers significant reductions while improving fuel efficiency,” said Dan Ditri, Head of Energy & Carbon, Colas Rail.
“It's a seamless, high-impact solution that helps our locomotives and on track machines burn fuel more effectively, run cleaner, and generate substantial cost savings."
The evaluations were carried out in 2024 in partnership with A&S International and verified by third-party emission specialists and showed a 4.5% improvement in fuel efficiency and significant emissions reductions.
In the tests, emissions demonstrated 63.2% less carbon monoxide, 47.5% less sulphur oxide, and particulate matter dropped by over 30%.
Sulnox Chief Executive Ben Richardson added:
“Sulnox is committed to being part of the solution for the rail industry, helping to reduce emissions significantly, while delivering fuel cost savings and supporting participants to meet ESG goals."
