The Krupp MaK G 1204 BB is a powerful diesel-hydraulic, four-axle locomotive designed for demanding shunting and mainline freight operations. Built in 1985, the locomotive offered is equipped with an MTU 12V396 TC13 engine rated at 1,120 kW, a Voith L5r4U2 hydraulic transmission and a maximum speed of 80 km/h. Its 80-ton service weight, B’B’ wheel arrangement, 260 kN tractive effort and 60-metre minimum curve radius combine substantial hauling capability with operational flexibility for industrial railways, ports, construction trains and freight services. The G 1204 BB is part of MaK’s proven locomotive range; only 18 units were built between 1981 and 1991. Narrow engine hoods support good buffer visibility, while the robust design provides accessible equipment and practical maintenance characteristics. The locomotive is approved for operation in Germany under EBO regulations and includes PZB90 train protection, cab radio, radio remote control and a cooling-water power generator. Its latest general inspection was completed in June 2026, with the overhaul interval stated through June 2032 (+2). A compelling opportunity for operators and investors seeking to buy a high-performance MaK G 1204 BB locomotive.
