EU Stage V compliant: Cat engines for clean and powerful mainline locomotives
Zeppelin Power Systems offers a comprehensive portfolio of Cat diesel engines for mainline locomotives that meet the highest demands for performance, efficiency, and environmental friendliness. With a wide power range from 82 kW to 3,000 kW, the engines are ideal for use in various locomotive types – from shunting locomotives to powerful mainline locomotives.
A standout feature of our Cat engines is their compliance with the strict EU Stage V 2016/1628 EC (RLL) emissions standards. These emissions-optimized engines use state-of-the-art exhaust aftertreatment technologies, including diesel particulate filters (DPF) and selective catalytic reduction (SCR), to drastically reduce harmful emissions and ensure environmentally friendly operation.
Whether for passenger trains that require reliable and efficient power for passenger transport, freight trains that demand high performance and robustness for heavy loads, or car trains and factory railroads that require flexibility and adaptability in operation – Zeppelin Power Systems offers tailored solutions for every application.
