The rail system in the Recife region can transport approximately 400,000 passengers daily. Failure drastically decreases its carrying capacity. An example of a failure that occurs frequently is the so-called false occupancy failure. False occupancy failures occur when the train detection mechanism for part of the route is defective, forcing the driver to take manual control, increasing the risk of accidents. One of the solutions is to increase the capillarity of the railway system by adding alternative routes. In this context, this work proposes a set of models for evaluating the performability of railway systems. A case study using the Recife railway system was used to show the applicability of the proposed models, where it was possible to increase the system availability by practically 50% with the addition of alternative routes, also improving the performance metrics.
