Nowadays railway traffic is managed automatically using Centralized Traffic Control (CTC) systems. Despite these systems are very robust, they are not free of failures. In those situations, traffic management has to be performed manually increasing the probability of accidents due to the occurrence of human errors. Advances in wireless communication technologies and distributed systems enable the design of new intelligent transportation systems that could be used in conjunction with CTC systems. This paper identify some security weaknesses in the way in which the railway traffic is regulated in emergency situations and presents a backup decentralized traffic management system which is focused in the resolution of these deficiencies, providing additional security levels and services.
