This development strategy is also based on studying the evolution of the railway sector in Ukraine:

• Infrastructure modernization: track reconstruction, construction of new 1435mm gauge routes, and implementation of new technologies to increase high-speed railway sections.
• Logistics centers: the creation of logistics hubs to optimize transportation processes by expanding the number of 1435mm tracks and their connection with the 1520mm gauge.
• International cooperation: the development of railway corridors with Europe and Asia, which can significantly strengthen foreign economic relations.

To achieve the established goals, in 2024, various turnout projects were designed and certified for serial production, including turnouts crossing the 1520mm and 1435mm track gauges for border crossings of the Ukrainian railway to the railways of neighboring European countries, an R65 turnout with a 1435mm gauge on a reinforced concrete sleeper, and a 49E1 turnout produced for European railways.
