Berkshire Hathaway’s Marmon Rail has unveiled ProTecht, a proprietary mobile cleaning system that brings safer, more sustainable, and highly efficient on-site tank car maintenance to rail yards across the U.S. and Canada. Operated by Marmon Rail brands UTLX in the U.S. and Procor in Canada, ProTecht is the rail industry’s first mobile, autonomous cleaning solution for tank cars.
Tank car cleaning — traditionally a hazardous process requiring workers to enter confined spaces with potential chemical residues — is now automated with ProTecht’s patent-pending technology. Developed over four years by inventor Evan Ingram, the system is compatible with all tank car types and offers three cleaning modes: water filtration for light residues, steam injection for midgrade commodities, and a high-impact automated cannon for hardened residues.
By using a closed-loop system that filters and reuses water and detergent, ProTecht reduces waste, lowers environmental impact, and boosts operational uptime. The mobile design eliminates costly transport to fixed cleaning facilities, cutting downtime and improving fleet utilization.
“Marmon Rail has long led the industry in railcar repair,” said Jay McGill, President, Repair Services, On-Site & Mobile. “ProTecht builds on that legacy with a cutting-edge system that is safe, sustainable, versatile, and purpose-built for on-site deployment.”
