Rail milling is an established maintenance technology that is applicable to all maintenance strategies. The innovative ROMILL Urban 3 E³ high-performance transit-milling machine incorporates the next generation of electric rail milling. With its high-capacity battery, the hybrid drive system allows for up to 3 hours of emission-free operations (no CO, CO2 or NOx, etc.). In addition, an integrated Tier 4 F diesel engine acts as a range extender and provides quick-charge capabilities.

The revolutionary new cutter head design results in longer tool life, allowing extended operation capabilities without tool changes. The machine is equipped with state-of-the-art measurement technology, including metal removal, transversal profile, longitudinal profile, and eddy current system.
