Railroads are an important mode of transportation worldwide. The world’s railway network spans over 1.3 million route-kilometers (807,782.55 miles)*. We’ll look at applications of Lean and Six Sigma in railroads from Britain, Slovakia, and Saudi Arabia and finish with a video of the 15 most dangerous railways in the world.
