Does anybody know why you hear the train wheel SCREECH when the train makes a curve?
russ_watters said:My guess would be that the axle is solid so at least one of the wheels has to be slipping since the outer and inner tracks are different lengths.
Train wheels screech on curves due to a phenomenon called "wheel/rail squeal." This occurs when the train's wheels and the track's rails come into contact at an angle, causing vibrations and a high-pitched noise.
While it may be unpleasant for passengers, train wheels screeching on curves is not necessarily dangerous. It is a natural occurrence and does not indicate any immediate safety concerns.
In most cases, screeching train wheels do not cause any significant damage to the train or tracks. However, if the screeching is excessive or occurs frequently, it can lead to increased wear and tear on the train's components and the tracks.
Yes, the speed of the train does affect the screeching of the wheels on curves. The faster the train is moving, the more likely it is to produce a louder and more noticeable screech. This is because the wheels are rotating faster and creating more friction with the rails.
Train engineers can reduce the screeching of wheels on curves by implementing various measures, such as using lubricants on the rails and wheels, adjusting the train's speed, and maintaining proper wheel and track maintenance. Additionally, newer trains may have design features that reduce the occurrence of wheel/rail squeal.
