Turns out the reason is
In today’s convenient transportation system, trains have won the hearts of many travelers due to their unique advantages. However, a concerning and controversial phenomenon while traveling by train is that the toilets on trains are directly connected to the tracks.
This design surely raises doubts for passengers, especially from a hygiene and environmental protection perspective. Many people can’t help but wonder: Why do train toilets use a system that discharges waste directly onto the tracks? Does this result in dirty tracks
First, let’s explore how train toilets work. Traditional train toilets often use a “direct discharge” system, meaning that when passengers use the restroom, the waste is discharged directly through a pipe onto the tracks below. The original purpose of this design was to simplify the waste disposal process while the train was in motion and to avoid problems like unpleasant odors and water accumulation in the toilet.
Compared to other modes of transportation, trains move at high speeds, and the space between the tracks is relatively wide. Designers believe that this discharge method will not have a significant negative impact on the environment. Moreover, when the train is running at high speeds, the waste is quickly dispersed by the airflow, thereby reducing direct pollution to the tracks and surrounding environment.
