Fuelling AdBlue
Cairn Cross delivers professional fuelling and AdBlue facilities for UK rail depots and infrastructure, providing safe, efficient, and compliant refuelling and additive systems for locomotives and rolling stock.
What Are Rail Fuelling & AdBlue Facilities?
Rail fuelling and AdBlue facilities are specialised infrastructure systems within rail depots and maintenance hubs, designed to refuel trains and rolling stock safely and efficiently.
- Fuelling systems provide diesel or alternative fuel to locomotives and multiple-unit trains.
- AdBlue facilities store and dispense diesel exhaust fluid to reduce emissions in compliance with environmental regulations.
These facilities are critical for:
- Safe refuelling of trains and rolling stock
- Compliance with UK rail operational and environmental regulations
- Maintaining operational efficiency and reducing downtime
- Protecting depot staff and the environment
Cairn Cross designs and installs fuelling and AdBlue facilities that are robust, safe, and fully compliant with UK rail and environmental standards.
