Execution of the design of the signalling belonging to a railway system must take various aspects into consideration, given that all factors are interconnected. The infrastructure to be implemented must also take into account the capacity of the trains to provide the desired service, and hence to comply with expectations in the headway calculated in order to meet passenger demand. An analysis of such systems on real platforms is highly costly, one solution being first to develop simulators which can work independently and which offer reliable results in line with reality. The Hamlet tool developed at Citef (Railway Technology Research Centre of the Universidad Politécnica de Madrid – UPM) is intended as a simulator capable of providing results for analysis and possibilities to optimize aspects of the infrastructure studied. This paper outlines in specific terms the techniques developed and validated for analysis of compliance with headways in operating plans and strategies for the optimization of the block distribution of lines for the purpose of improving this headway. In order to evaluate properly the developed tool and techniques, it has been analyzed a real line operated using ERTMS level 1 signalling system.
