The utility model relates to a railway freight car bogie for meter-gauge lines, which comprises a bottom bolster and a foundation brake rigging, the bottom bolster is provided with a lower center plate integrated with the bottom bolster, and the railway freight car bogie solves the inertial mass problem that the bolts of the lower center plate can be easily loosened and broken. Because both ends of the lower center plate are respectively provided with a safe lifting lug which can prevent throwout caused by derail, the train body can be prevented from being separated from the bogie when the train derails, and hazards caused by derail can be reduced. Because cast iron gapped lower side bearings are arranged in the side bearing boxes of the bottom bolster, the curve passage capability and twisted line adaptability of a car can be enhanced, and the manufacturing and maintenance costs are low. Because a brake beam in the foundation brake rigging adopts an integrated weldless structure, fatigue cracks caused by welding are avoided, and the inertial mass problem of the failure of the brake beam caused by cracks is solved. Because a lower pull rod safety hanger is arranged on the brake beam, running accidents caused by the separation of the brake beam are prevented, and thereby the running safety of the car is improved. The utility model has the advantages of simple structure, convenient maintenance and low production and maintenance costs.
