Comparison of constructional aspects of different railway point machines

Ovalı, Orçun
In the last years, railway systems are becoming more popular all over the world, especially in the European Union. Turkey has also started to develop completely domestic products and systems for the railway trains, signaling and infrastructure. Point machines are one of the critical safety devices for the railway signaling and infrastructure. They play an important role in the safe running of rail services. Hence, they have to be quick for the throwing and reliable for the locking of point blades. This study contains research about modern point machines commercially available in the market and investigations on some of these machines used by Turkish State Railways (TCDD) the major authority running the infrastructure in Turkey. The main objective of this study is to compare different railway point machines in terms of their constructional aspects. This assessment includes three main steps. The first step is to perform research about modern point machines and their operational characteristics. The second step is the detailed investigation of four different point machines that are currently used at the railways operated by TCDD in Turkey. The final step is about comparison of mainly constructional aspects of these investigated point machines for the purpose of preparing background and guidelines for the development of a novel and domestic point machine.
