A control method and control device for degraded operation of a locomotive, and a locomotive are provided. The control method for degraded operation of a locomotive includes the following steps: step 1: when a power source of a locomotive fails, calculating a sum of available power of all power sources, P_total=P1+P2+... +Pk; step 2: defining k as an efficiency coefficient of the locomotive, P_a as fixed load power of the locomotive, and P_b as a power safety margin, and calculating first traction force when a current speed of the locomotive is v by using the following equation: Fv'=k(P_total-P_a-P_b)/v; and step 3: comparing Fv' with Fv, and taking the smaller value as maximum available traction force when the current speed of the locomotive is
