C70 4-Axle General-Purpose Open Wagon

RailMac C70 4-Axle General-Purpose Open Wagon

The C70 general open wagon was developed in 2005 to satisfy the increasing railway goods transportation needs in China. The wagon has a loading capacity of 70t, its wagon body is welded by high-strength weather-resistant steels.

One pair of side open double doors and six upturned lower side doors are installed on the side walls of both sides of the C70 wagon body. A new type of locking structure is adopted for the double doors, and a full-length groove lockbox is set outside the lock rod, which not only prevents the lock rod from being bumped and deformed but also greatly improves the anti-expansion ability of the door panel. The lower door lock adopts an eccentric compression structure. When the upper door lock is closed, the handle can prevent the lower door lock from jumping out and avoid accidental door opening. The operation is simple, safe, and reliable.

The C70E open wagon is an upgrade version of the C70 wagon. Its end walls and side walls are increased by 100mm to expand the loading volume.

As part of SinoMac, RailMac provides full life‑cycle services for the C70 4-Axle General-Purpose Open Wagon, including design, system supply, installation, commissioning, after‑sales training, spare parts supply, troubleshooting and overhaul support, ensuring stable and efficient performance throughout its service life.

Advantages of C70 4-Axle General-Purpose Open Wagon

As a general-purpose open wagon, it transcends niche cargo limitations, seamlessly handling coal, minerals, construction aggregates, and even packaged goods. Its open-top design enables fast loading by heavy machinery, making it the go-to choice for diverse bulk cargo operations, thereby maximizing asset utilization for rail operators.
With a 70 t net loading capacity and a 77 m³ large volume, the C70 maximizes single-trip cargo throughput. The lightweight 23.8 t tare weight minimizes deadweight, delivering an excellent payload-to-weight ratio that reduces per-tonne transportation costs and lowers energy consumption per trip.
A maximum speed of 120 km/h under full load allows it to keep pace with high-priority freight schedules, shortening delivery cycles for time-sensitive bulk materials. The 145 m minimum curve radius ensures compatibility with both straight and curved track sections, supporting flexible deployment across extensive rail networks.
Built with a durable 23 t/axle load rating, the wagon withstands rigorous heavy-haul conditions while maintaining compliance with standard rail infrastructure requirements. Its robust construction is paired with efficient maintenance profiles to minimize downtime and ensure long-term, reliable service across its operational life.
