Robel Bahnbaumaschinen (Robel) has announced that it is to deliver an energy efficient hybrid rail milling machine to Plasser American Corporation (PAC), headquartered in Chesapeake, Virginia.

Robel, alongside its partners Schweerbau International (SBI) and Vogel & Plötscher, will deliver the rail treatment system in summer 2022. The machine, called the Romill CMS3e, is equipped with a hybrid drive system, which consists of a battery and an exhaust reduced Diesel range extender allowing for low emission rail maintenance.

SBI specifically developed the vehicle design, drive system and milling technology to meet the maintenance requirements of transit systems. The three-piece machine consist has been designed to fit into tight tunnel clearances in North America, and it fits into the tight tunnels of the London Underground.

Romill CMS3e is equipped with the latest electric milling technology for the reprofiling of low-quality track. The spark and dust free rotational cutting process includes by-product collection on the train for recycling. In addition, a high-performance polishing process is implemented to create a noise-optimized surface finish.

Thomas Blechinger, PAC President said, “In 2022 we will offer battery powered, emission free rail treatment solutions for transit systems with the CMS3e high performance milling machine. With this innovative technology, we will proverbially smooth the track for safe and environmentally friendly rail maintenance in North America.”
