Metro railways network becomes an integral part of our life. The failure-resistant network which uses power cables of different capacities for supplying energy to the metro system. The study of the metro network system facilitates carrying out reliability modelling and profit analysis of this energising power system through power cables. The cables are laid in loops for feeding supply to substations from each station. Initially, one cable is in working state, and the other cable of same voltage capacity is taken as a hot standby. In case of failure, the second cable can be made operative without delay. Inspections have been carried out at each failure to check whether the system is repairable or not. The calculations to measure System Effectiveness and Profit Analysis are done using “Semi-Markov Processes” and “Regenerative Point Technique”. The results obtained through calculations have been showcased and verified through different graphs with discussions and conclusion.
