Merits & Demerits of Different Types of Rails

Introduction

Railway engineering is a crucial aspect of infrastructure development, focusing on the design, construction, and maintenance of railway systems. The type of rail used can significantly influence the performance, cost, and longevity of a railway line. This document will explore various types of rails—such as steel, concrete, and wood—highlighting their respective merits and demerits.
