The utility model relates to the technical field of rail transportation, in particular to a ballast hopper car chassis capable of changing rails, which comprises a pair of side beam assemblies arranged in parallel, end beam assemblies are arranged at two ends of each side beam assembly, the end beam assemblies are inwards connected with traction beam assemblies, and the two traction beam assemblies are connected through a middle beam assembly. The lower portion of the traction beam assembly is provided with a narrow rail side bearing suitable for a narrow rail and a standard rail side bearing suitable for a standard rail. The stable and reliable frame structure is obtained by arranging the side beam assemblies, the end beam assemblies, the traction beam assemblies and the middle beam assemblies, the self weight of the frame structure can be reduced under the condition that the strength requirement is met, and energy consumption in the operation process is reduced; meanwhile, the narrow ...
