What are the factors that make locomotives prone to slipping during operation?

Here are the factors that make locomotives prone to slipping during operation: 1. The starter one-way gear roller slips, causing the gear to lose its one-way function: The main reason is that the spring force of the one-way roller rebound weakens or fails. 2. The main circuit is connected prematurely, preventing the rotating gear from meshing with the flywheel ring gear: Due to the lack of regular maintenance of the starter, the front end cover copper sleeve becomes severely loose, the starter shaft bends under force, and the starter gear shift fork gets stuck or breaks. 3. Excessive damage to the ring gear meshing teeth makes normal meshing impossible: Due to the regularity of engine shutdown rotation, the engine crankshaft flywheel disk often stops at three different points with an angle interval of 120 degrees, causing each start to begin from these three points, where the torque is very high at the beginning of startup.
I've been driving trains for nearly twenty years, and idling issues are frequently encountered, especially under certain special conditions. Track conditions are the most critical factor. For example, on rainy days when the tracks are slippery, the friction between the wheels and the rails decreases, and a slight throttle increase can cause the wheels to idle. In industrial areas with a lot of oil contamination, oil or lubricant buildup on the tracks can cause significant slipping when the train passes. Additionally, if the wheels are severely worn and not replaced in time, insufficient grip can easily lead to idling. Starting or climbing on steep gradients with unstable power output can also cause this issue. My personal experience suggests that smooth operation is key—avoid sudden acceleration. Also, a quick inspection of the track conditions before each trip can help reduce idling occurrences. Regular maintenance of the locomotive is crucial; replace the wheels when necessary and don't delay for cost-saving reasons. Overall, controlling the throttle and paying attention to environmental details are key to prevention, as negligence could compromise safety.
