The locomotive is a self-propelled vehicle which pulls or pushes a railway vehicle to run and does not load business load per se, and is commonly called a locomotive. The locomotive is the least energy consuming land vehicle, as calculated by the amount of fuel consumed per ton of kilometer transported. In taiwan and other areas of china and continental areas, a heavy motorcycle is also called a "motorcycle".

The energy consumption of railway transportation is mainly reflected in the running process of locomotive traction trains, and under the operation management conditions of a set operation diagram, a train marshalling plan and the like, a plurality of different traction operation control methods exist for completing a specified transportation distance of the same train within a specified time, and different operation methods directly cause different energy consumption of train running.

Currently, the impact of locomotive crew maneuver levels on energy consumption is not negligible. The same train consumes different energy sources due to different operation methods of locomotive crew members, the operation of the crew members with proper braking time and stable operation can be accurately mastered by knowing the longitudinal section of the line, the operation speed of the train and the section operation time, and the fuel consumption is less. Otherwise, the fuel consumption will increase and the unit consumption will rise. Meanwhile, the stable operation of the train reduces the impact stress of the train, thereby reducing the abrasion of the locomotive and the vehicle.

However, when a locomotive runs on a track, an emergency situation is easy to occur on the track, when people or objects appear on the track, the train needs to be braked in order to avoid personal accidents and property loss, but when the locomotive crew sees the people or objects appearing on the track, emergency braking is normally adopted to reduce the braking distance, so that not only is the fuel consumption increased, but also the distance of the objects in the locomotive is easy to shake, and the damage of the locomotive is easy to cause.
