At Arrow, we understand that keeping specialist rail equipment in top condition requires more than just routine maintenance – it demands the right cleaning solutions. When Colas Rail approached us during the refurbishment of their Kirow 1200 rail crane, the stakes were high. They needed a cleaner powerful enough to cut through heavy traffic film, oil, and grease, but gentle enough to protect newly painted surfaces. Previous products had caused paintwork damage, leading to unnecessary cost and downtime. We knew Trailerwash could deliver the balance they needed.
Colas Rail: Driving UK rail infrastructure forward
Colas Rail is one of the UK’s leading rail infrastructure companies, playing a vital role in building, renewing, and maintaining the railway network. With operations spanning track, signalling, electrification, rolling stock, and plant, Colas Rail is trusted to deliver reliability and efficiency on some of the nation’s most critical rail projects.

Why the Kirow 1200 Crane Matters
Among Colas Rail’s impressive fleet, the Kirow 1200 rail crane is a true workhorse. With a maximum lifting capacity of 125 tonnes, this heavy-duty crane combines power with precision. Its lift-and-carry capability allows it to move loads across a worksite, supporting a wide range of applications:
- Lifting and installing track sections during renewals
- Handling overhead line gantries
- Supporting bridge reconstruction projects
- Recovering derailed rolling stock in emergency situations
Compatible with Network Rail’s modular Tilting Wagon system, the Kirow 1200 offers versatility and efficiency that few machines can match. Following a major refurbishment, ensuring it looked and performed at its best was essential – and that’s where Trailerwash came in.
