Conclusions Capacity Analysis by Simulation Methods: Case Study Xalapa, Mexico 2 Introduction Methodology Case Study Analysis Conclusions Characteristics of the Mexican Railway System Railway operation in Mexico: . Freight transport oriented (long distances) . Mainly non-signalized operation . “Private” operation (concessions) Source: elfinanciero.com.mx . Almost no passenger transportation Typical Mexican Freight Train . Metro/ light rail systems in Mexico City, Monterrey, Guadalajara . Unstructured operation pattern . Low speeds and many level Photo: Stefan von Mach crossings Very low traffic railway Line in Yucatán Photo: Stefan von Mach Bombardier/ CAF Metro in Mexico City - Capacity Analysis by Simulation Methods: Case Study Xalapa, Mexico 3 Introduction Methodology Case Study Analysis Conclusions Movement Authority . Movement Authorization procedures can be divided into two categories: • Signal – Controlled • Non Signal – Controlled . Signal-Controlled is very well known in Europe (standard) . Non Signal-Controlled • Common in North America • Verbal or Written Authority (Track Warrants) • Communication via Radio or Telephone • Dispatcher Capacity Analysis by Simulation Methods: Case Study Xalapa, Mexico 4 Introduction Methodology Case Study Analysis Conclusions Map of the Mexican Railway System Mexican Railway network.
