The paper is a description of an actual operations research (O.R.) exercise carried out on the South Eastern Railway during the past two years or more. In this respect it is as exclusively goal-oriented as were the exercises of the founding fathers of the O.R. movement during World War II. By a close study in the field of some of the more basic operations of the railway particularly of those service counters like marshalling yards and loco repair depots whose utilisation factor exceeded 0.75, it was possible to give the operations of the S. E. Railway an entirely new look. This is shown by the increase of 17 to 22 per cent in the indices of mobility and productivity of the railway's hardware of locos and wagons. As a result the operating ratio (working expenses per 100 rupees gross earnings) decreased from 71.19 per cent in 1966-67 to 65.72 per cent in 1968-69, the return on capital at charge increased from 8.1 per cent in 1966-67 to 10 per cent in 1968-69 and profit from Rs. 134 millions in 1966-67 to Rs. 187 millions in 1968-69 despite the inevitable increases in costs of staff and materials during these two years. These financial gains are all the more remarkable as during the year 1968-69 the South Eastern Railway suffered a loss of Rs. 35 millions due to the total closure of its Each Coast line for over a month on account of two successive unprecedented cyclones in Orissa in November 1968.
