My job, commonly known as "rail track doctor", is to examine railway tracks and find flaws. During the past 20 years since I joined the company, I have walked along nearly 40,000 kilometers of railway tracks. We walk to wherever the network extends to. It is a technical and ordinary job, but also a job with great responsibility.
