Lean Six Sigma Lean Six Sigma is a business improvement methodology that combines the principles of Lean Manufacturing and Six Sigma quality management techniques. Together, Lean and Six Sigma provide a powerful toolkit for improving business performance by reducing waste, improving quality, and increasing efficiency. Lean Six Sigma has been widely adopted in many industries, including manufacturing, healthcare, and finance, and has been shown to produce significant improvements in quality, customer satisfaction, and profitability. Six Sigma Six Sigma is a data-driven methodology used to improve processes and reduce defects in products and services. It aims to achieve a level of quality where there are very few defects (less than 3.4 per million opportunities) by identifying and eliminating the root causes of problems.

There are several types of braking systems used in rolling stock, which are as follows: Air brakes: Air brakes are the most common type of braking system used in rolling stock. They work by using compressed air to actuate the brakes on each car in the train. Air brakes can be either direct release or graduated release. Dynamic brakes: Dynamic brakes work by converting the kinetic energy of the train into electrical energy, which is then dissipated as heat. This helps to slow down the train and reduce wear on the brake pads. Electromagnetic brakes: Electromagnetic brakes use an electromagnet to actuate the brake pads, which are pressed against the wheels of the train. This type of braking system is commonly used in high-speed trains. Regenerative brakes: Regenerative brakes work by using the electric motors on the train to generate electricity when the train is slowing down. This electricity is then used to power other systems on the train, such as the lights and air conditioning. H
