Tests of the catenary system for the first Russian high-speed railway have been successfully completed. The verification confirmed that the infrastructure is capable of supporting train movement at speeds up to 400 km/h. The work was carried out by RZD specialists in cooperation with Russian equipment manufacturers.

The tests lasted almost a year and began in August 2025 on an experimental section 800 meters long. During this time, specialists checked the operation of all elements of the catenary system, their compatibility and stability at high speeds, and also evaluated the tension parameters of the contact wire.

Following the tests, RZD reported that all system components comply with the technical specifications and project requirements. After the completion of the test program, a decision was made to start production of the initial series of components.

Special attention was paid to the stationary diagnostic system. On the test section, 32 sensors were operating, which automatically monitored the condition of the catenary system and recorded its main parameters.

The development of the equipment became one of the largest cooperation projects for the domestic railway industry. Components were produced by about 80 Russian enterprises, which collectively manufactured more than 800 different parts.

The first Russian high-speed railway will connect Moscow and St. Petersburg. Construction of the 679-kilometer line is planned to be completed in 2028. After the line is put into operation, the travel time between the two cities will be reduced to approximately two hours.
