The final assembly of the first high-tech track-lining-tamping-straightening machine PMA-3 has been completed at the "Kalugaputmash" enterprise. According to representatives of the plant, the equipment has already passed internal checks and will begin certification tests in 2026.
The development of PMA-3 was carried out with the support of the Ministry of Industry and Trade of the Russian Federation and is focused on increasing the autonomy and efficiency of the railway industry.
According to engineers, the machine is capable of performing a full cycle of work on the maintenance of the railway track: alignment and straightening of the track, compaction of ballast under the sleepers and at their ends, as well as stabilization of the track under all types of rails. Special attention was paid during the design to reducing the so-called technological "windows" — temporary interruptions in train traffic necessary for carrying out repair work.
Among the key characteristics of PMA-3 are a productivity of up to 3300 sleepers per hour with simultaneous tamping of three sleepers, a self-propelled speed of up to 90 km/h, and a minimum required number of service personnel — only three people.
It is important that only Russian components and technologies were used in the creation of the machine, which ensures technological sovereignty and simplifies the logistics of supplies and maintenance.
