The DD-13 Diesel Hydraulic Locomotive is a proven two-axle bogie locomotive designed for dependable performance across industrial and mainline rail environments. With a B-B axle arrangement and an operating weight of 56.0 tons, the DD-13 strikes the ideal balance between tractive capability and track compatibility.

Powered by two Niigata Diesel DMF31Z 6-cylinder engines, each rated at 500 PS at 1,500 RPM, the locomotive delivers reliable power for a wide range of haulage tasks. Power is transmitted through the Niigata DBSFG-138 three-stage hydraulic torque converter, ensuring smooth and efficient operation across varying load conditions.

Equipped with a 1,500-litre fuel tank, DL/4B single automatic air brake with hand brake, dual C1200 reciprocating air compressors, and a 24V AC electrical system, the DD-13 is built for long-haul reliability and ease of maintenance in the field.
