DeRoI-class locomotive (Toshiba)

The DeRoI-class locomotive is a type of diesel-electric locomotive manufactured by Toshiba for use on railway networks. Specific details regarding the "DeRoI" designation, such as its origin or meaning, are often specific to the railway operating the locomotives. This designation is not universally applied and likely represents a specific internal classification used by a particular railway company that procured these locomotives from Toshiba.

Generally, Toshiba is a well-regarded manufacturer of locomotives known for their reliability and performance. The DeRoI-class, like other Toshiba diesel-electric locomotives, likely incorporates a diesel engine powering an electric generator. This generator then supplies electricity to traction motors, which drive the wheels. This configuration allows for efficient power transmission and precise control.

Information on specific specifications such as horsepower, weight, tractive effort, and gauge is dependent on the specific order placed by the client railway. Details regarding the intended usage, such as freight or passenger service, and the operational railway system are essential to understanding the DeRoI-class's specific characteristics and performance capabilities. Without more specific information about the operator and operational context, it is difficult to provide a comprehensive description.
