Russia: Aleksandr Pikalov, Deputy General Director of Remputmash, part of Sinara–Transport Machines, STM, has presented the technical specifications for a forthcoming tamping machine at the INNOPROM exhibition in July. The company announced preparations for its production at the beginning of the year.
The PMA-3 has been designed for use in track lining and profile treatment operations under the track and on both sides of sleepers with rails of types R50, R65 and R75. It is also suitable for use in stabilisation applications. The machine reportedly has a maximum capacity for lining and tamping of 3,300 sleepers per hour, a speed of up to 90 km/h when moving self-propelled, and a 550 kW main traction system. Mr. Pikalov confirmed that the machine is capable of tamping three sleepers simultaneously.
The new track machine under development offers a number of advantages, including a modular cabin that will be used on five other track machines produced by STM. The PMA-3 will also be equipped with a smart system for assessing the readiness of the working area, applying geographic information solutions for tampering, and monitoring of the technical condition.
Mr. Pikalov confirmed that the PMA-3 is scheduled for certification in 2025 and that the machine will be used, among other things, in the construction of Russia’s first high-speed railway line between Moscow and St. Petersburg.
At the end of June, Russian Railways announced the purchase of up to five tamping machines under a futures contract. The new equipment is intended to replace the previously supplied Dynamic 09-3X machines from Remputmash and Plasser & Theurer. The PMA-3 is fully compliant with the technical specifications set out in the tender as well as the PM-03-48 tamping machine developed by Engineering Service-Putmash. Russian Railways is currently assessing the tender submissions.
