Moscow operates one of the largest and most heavily used metro systems on the planet, with over 260 stations and a daily ridership exceeding 9 million passengers. Beyond the metro, Moscow's mainline railway network radiates to all corners of Russia, while massive industrial zones β including freight hubs, seaports along the Moskva River, and sprawling crane rail installations in logistics parks β demand uninterrupted, high-performance rail infrastructure. Rail joint welding is not merely a maintenance activity in Moscow; it is a strategic imperative that underpins the entire city's mobility and industrial output.
The ongoing Big Circle Line (BCL) project β the world's longest circular metro line β and the Moscow Central Diameters (MCD) commuter rail programme together represent billions of roubles in rail infrastructure investment. These projects require thousands of aluminothermic rail joint welds that meet GOST standards and can endure extreme cold, heavy passenger loads, and 24/7 operation cycles. RMTS supplies welding kits precisely formulated for P65 rail profiles widely adopted across Russian metro and mainline systems.
Moscow and its satellite cities host numerous heavy industrial facilities, including the ZIL automotive complex redevelopment, Khimki logistics parks, and Domodedovo freight terminals. Overhead crane rails in these environments experience enormous cyclic stress loads. Aluminothermic welding produces continuous, joint-free crane rail tracks that significantly reduce maintenance downtime and increase load-bearing reliability β a critical advantage for facilities operating heavy overhead cranes around the clock.
Moscow's temperatures regularly plunge below β20Β°C in winter, creating severe challenges for conventional welding methods. Thermit (aluminothermic) welding offers a decisive advantage: the self-contained exothermic reaction reaches approximately 2,500Β°C, making it far less dependent on ambient temperature than electric arc welding. RMTS's cold-weather welding kits include preheating mould systems and low-temperature-optimised thermit portions, ensuring reliable weld formation even in sub-zero Moscow winters without the risk of cold cracking.
Moscow is the hub of Russia's national railway network managed by RZhD (Russian Railways). Major trunk lines β including the Trans-Siberian, MoscowβSt. Petersburg high-frequency corridor, and the M11/M12 speed upgrade projects β require continuous welded rail (CWR) over thousands of kilometres. Rail joint welding quality directly impacts ride comfort, track geometry stability, and maintenance intervals. RMTS provides thermit welding materials certified for P65 and T62 rail grades, the dominant profiles used throughout Russia's mainline network.
With significant portions of Moscow's metro and suburban rail infrastructure originally constructed in the Soviet era, periodic joint repair and re-welding form a critical segment of annual rail maintenance budgets. RMTS's portable welding equipment β including our electric rail cutting machines, rail pulling machines, and profile grinding machines β enables efficient in-situ repair operations with minimal track possession time, helping Moscow's rail operators maintain service frequency without extended closures.
Russian rail projects demand adherence to GOST standards (e.g., GOST R 53985) governing thermit welding procedures, material composition, and weld inspection. RMTS's R&D team has invested significantly in understanding and aligning with Russian technical requirements. Our welding kits and consumables undergo rigorous internal testing to ensure they meet β or exceed β GOST specifications, giving Moscow-based contractors and railway authorities the technical confidence to approve our materials for use on their networks.
Russia is aggressively transitioning from jointed track to CWR across mainline, commuter, and urban metro systems. This trend is driven by the need to reduce noise, vibration, and track geometry irregularities while extending rail life. The shift creates surging demand for high-quality thermit welding materials capable of producing defect-free joints at speed and scale.
Moscow rail contractors are increasingly deploying semi-automated welding systems to improve weld consistency, reduce human error, and accelerate project timelines. RMTS's range of precision equipment β including profile grinding machines and rail rust removal machines β integrates seamlessly into semi-automated workflows, boosting productivity on Moscow's time-critical rail projects.
Amid evolving international trade dynamics, Russian rail contractors and engineering firms are increasingly sourcing welding materials, tools, and consumables from trusted Chinese manufacturers. Chinese suppliers offer competitive pricing, high production capacity, and the ability to customise products for specific Russian rail profiles (P65, T62). RMTS has been at the forefront of this trend, actively serving Russian clients with dedicated technical support.
Moscow's transport authority Mosgortrans and RZhD are increasingly evaluating rail materials on lifecycle cost rather than upfront purchase price. Thermit welding β when performed with premium materials β yields welds with service lives exceeding 20 years, dramatically reducing the frequency of re-welding, track possession events, and associated operational disruptions. This lifecycle cost advantage is a key driver of demand growth for premium welding solutions.
The rapid growth of e-commerce and logistics infrastructure around Moscow β including major distribution centres in Odintsovo, Podolsk, and Mytishchi β is generating new demand for industrial crane rail welding services. These facilities require heavy-duty rail joints capable of withstanding high-frequency crane movements and heavy point loads.
As Moscow-based rail operators and contractors adopt new welding technologies, the demand for supplier-provided technical training and on-site welding instruction has grown significantly. RMTS differentiates itself not only by supplying premium products but by deploying experienced technical teams to provide hands-on guidance, ensuring optimal weld quality on every Moscow project.
