4 Car DMU 120km/h Diesel Multiple Unit with Intelligent Network Control

The 4-car Diesel Multiple Unit (DMU) is a state-of-the-art train specifically engineered for non-electrified railway lines. With its self-powered design and flexible formation, this DEMU operates independently without the need for overhead catenary or power supply systems, dramatically reducing infrastructure costs while seamlessly connecting conventional speed lines, branch lines, and non-electrified sections. Combining high passenger capacity with rapid acceleration and green energy efficiency, it is the ideal solution for modern regional rail transport.

The DMU is tailor-made for non-electrified lines, including branch railways, intercity connections, tourist routes, and urban commuter services. It operates without overhead catenary, making it perfect for lines where electrification is not feasible or cost-effective.

The train offers a seated passenger capacity of 366, with spacious interiors designed for comfort during both short commutes and longer regional journeys. The humanized layout ensures a pleasant travel experience.

The combination of a lightweight high-strength body, mature bogie technology, and excellent vibration damping allows the DMU to navigate tight curves (as low as 150m radius on main lines) and steep gradients (up to 30‰) with stability and safety. The intelligent control systems further enhance performance under varying operational scenarios.
