The paper presents issues related to the process of monitoring the technical condition of railway turnouts and administration of data from measurement sensors cooperating with computer programs, enabling continuous tracking of changes and trends in the presented system, which is a railway turnout controlled by a switch point machine. The author points to the importance of remote diagnostics, mainly the moving turnout elements for appropriate intervention by the maintenance services. The paper also presents market needs in terms of the need to obtain appropriate field data, including changes in the turnout operation depending on climatic conditions and trends of changes depending on the wear of the rolling elements of the turnout. The author points to the need for monitor the condition of several most important points of the turnouts that have a direct impact on future potential: failures, damage, reduced availability of the railway line or a railway disaster. Attention was also paid to the need to use field data from the service work not only from the warranty period but also throughout the assumed whole life cycle of the turnout.
