This document discusses the history and evolution of rules governing working hours for railway employees in India. It covers key milestones like the Railways Amendment Act of 1931, the Rajadhyaksha Committee Report of 1946, and the Miabhoy Tribunal Award of 1969-1972. The Miabhoy Tribunal addressed issues raised by railway unions regarding classification of workers, weekly working hours, overtime pay, and more. The tribunal's decisions, which included maintaining existing classifications and permitting averaging of hours for certain workers, were accepted by the government. Current rules are based on the Railway Act and Railway Servants (Hours of Employment) Rules of 1961.
