The present work proposes a comparison among two methodologies: a line network model and a simulation model. These two approaches aims to measure the performance of, for example, the average total trip time for a given train route. It is assumed that there is no tracks changes involved and where it passes through several railroad crossings. The objective of this comparison is to present two performance analysis tools to determine the railroad line capacity for a given level of service. For these analyses the stretch of the railroad line for a network of servers in series is modeled or represented by a computational model representing the sub-stretches between the railroad crossing and the trains. These models can be used to estimate the impact on the trains travel time in congested areas. Numerical results are presented in single stretches of the railroad line of Centro Atlântica, as well as a comparison among the two methods.
