The objective of this paper to develop the conceptual model for managing the carrying capacity of urban railway during peak and off-peak hours For this firstly focus on the influencing factors and interactive relations of the rail carrying capacity of a low and high speed mode rail. In this paper six different models developed for an urban rail by the ratio of tracking low and high speed trains. Taking Jaipur metro rail corridor-1 in India as a case study The proposed model proved to be valid for utilizing urban rail capacity by low and high speed train concept. This paper contributes the previous related researcher’s history by modifying the concepts and methods are applied to improve the carrying capacity. As the train types increase in a network than more interference increases and less capacity occurred in a network In this paper, a model for estimation of the capacity of a network is presented.  The model is helpful for railway planners for capacity planning of a network.
