Close-up of the train wheel replacement process

Trains, also known as trains, trains are railway vehicles, this is one of the most popular means of transportation in the world today.

Trains consist of locomotives and specialized carriages that move on iron rails.

A railway track will typically have two main rails laid parallel to each other. Between the two rails is a series of crossbars placed perpendicular to them. These crossbars are called sleepers, and are usually rectangular in shape and made of wood or concrete.

The train wheels are metal, unshelled, and will move on this track.

The quality of train wheels plays an important role in ensuring safety throughout the operation of the train. Train wheels must meet strict standards for durability, rail grip, hardness, safety, etc. The production process of train wheels must go through 14 main steps including melting wheel steel, cutting blanks, heating, stamping, rolling, hot stamping, machining, hardening, cold printing, inspection, axle stamping, axle machining, wheel mounting to axle and coating.

Just like the wheels of other vehicles, train wheels must be periodically maintained and replaced if a flat wheel occurs. A flat wheel can occur when, after emergency braking, the wheel slips on the rail and creates a flat spot, no longer round, and when running again, it will vibrate and must be replaced.

The size of the train and the train wheels are quite large, so changing the wheels is not easy. Below is a detailed video about the process of changing train wheels, please watch.
