Influence of changing station layout over railway interlocking

The aim of the article is to present the influence of changing station layout over interlocking systems in train routes. There is often a problem in the process of doing for example application of interlocking system in exactly bigger stations when there are track changes in next phases of the project. Vividly small changes can influence in significant way for realization train and manoeuvre routes in such station. In case of that it is necessary to search the shortest road of making documentation and software which could be changes resistant. This resistance resulted by for example necessity of continuing leading railway when there is modernization on the station.
