The invention discloses a rainproof doorsill structure of a control cabin of a railway vehicle and the railway vehicle, the rainproof doorsill structure comprises a rain eave, one end of the rain eave is connected to the outer side of a control cabin door of the railway vehicle, and the other end of the rain eave inclines downwards and extends towards the outer side of a lower doorframe of the control cabin door of the railway vehicle; a cavity is defined by the doorsill on the inner side of the lower door frame, the doorsill comprises a flow guide part, the flow guide part is arranged at the end, close to the lower door frame, of the doorsill and inclines downwards, a plurality of notches are formed in the end, close to the lower door frame, of the flow guide part, and drainage holes are formed in the bottom of the lower door frame; according to the rainproof doorsill structure, the structure of a rubber barrier strip is omitted, the rain eave is directly connected to the outer side of the control room door, the structure is simplified, meanwhile, the sealing defect caused by deformation or aging due to rubber riveting is avoided, the doorsill with the flow guide part is adopted to guide rainwater entering the inner side of the lower doorframe, and the rainproof effect is good. And the gaps and the drainage holes are formed, so that the guided rainwater can be completely drained, and the interior of the railway vehicle is protected against rainwater invasion.
