Dual-mode locomotive can be operated as diesel electric as well as electric locomotive. While operating in non electrified routes, dual-mode locomotive works as diesel electric locomotive by drawing power from onboard diesel engine as the primary power source. The same works as an electric locomotive by drawing power from catenary in electrified sections.

The solution will help in operating a single locomotive continuously in electrified as well as non-electrified sections.
