The invention relates to a coach side wall frame structure with an emergency door frame and a coach. The coach side wall frame structure comprises a compartment door upper stringer, a compartment door lower stringer, a side window upper stringer and a side window lower stringer, which all extend horizontally; the coach side wall frame structure further comprises compartment door pillars, middle beam pillars, an emergency door upper stringer and an emergency door lower stringer, and emergency door front pillars and emergency door rear pillars. The mounted emergency door frame destroys the frame structure of the original coach bodywork, thus the upper and lower ends of the emergency door front pillars and the emergency door rear pillars are fixedly connected with the side window upper stringer and the compartment door upper stringer, respectively, and the emergency door lower stringer is fixedly connected to the compartment door upper stringer by bonding welding, so as to compensate for the strength and stiffness losses caused by the discontinuity of the side window lower stringer to the frame structure. By using such reasonable design, the coach side wall frame structure with the emergency door frame and the coach are provided, thus sufficient space of the emergency door is allowed, and reduction in the strength and stiffness of the original frame structure is avoided.
