In the same week that Russia experienced an unexpected drone attack on its airfields deep inside the country, explosions rocked several Russian railway tracks and the railway bridge into annexed Crimea was targeted with underwater explosives. Though these attacks lacked the novelty of Operation Spider’s Web, they underline the centrality of Russia’s railway network to its war effort. Transport is a crucial component of Russia’s strategic security considerations, with political heavyweights appointed by the Kremlin to oversee the country’s roads, bridges, railway networks and its inland waterway system. It is also no accident that the Chairman of the Board at Russian Railways, Andrei Belousov, is also defense minister. Presidential aide Nikolai Patrushev also manages the development of Russia’s waterways, which have important military implications for Moscow’s relations with China and activities in the Arctic. The link between transport and Russia’s strategic security is also enshrined in law. Since 2014, transport has been included among the so-called strategic sectors, alongside defense, oil and gas. The Kremlin considers these parts of the economy to be fundamentally important and upon which Russia’s national security rests, such as defense, oil and gas. Foreign investment in these enterprises is limited by law; they receive particular attention and funding from the federal center and usually play an important role in furthering Russia’s foreign and domestic policies, as well as its warfare. Railway networks are the only way that Russia’s ground forces and materiel can travel around the country at speed and en masse. They were how Russian and Belarusian troops amassed on the border with Ukraine in February 2022 and remain the only way that Russian ground forces can be sustained on the battlefield for a long period of time.

Ukraine, Belarus and Russia all use the 1,520mm Soviet gauge, which made commandeering the railways to move Russian troops into Ukraine relatively straightforward. As Russia was pushed back, it attacked parts of Ukraine’s rail network in the early part of 2022 to prevent the country maneuvering military reinforcements. Russia’s neighbors are acutely aware of this too. In the early days of the war, Belarusian partisans blew up Russian railway signaling boxes to delay trains carrying military equipment to the front. They were subsequently dealt with harshly. Ukraine also understood Russia’s reliance on its rail systems and has tried to destroy its own network to prevent Russia from pressing more deeply into Ukrainian territory, and to disrupt Russia’s railways inside the country, most notably in December 2023. In May 2025, neighboring Finland announced abruptly that it would be switching its entire network from the Russian to the European standard gauge system. Although this overhaul will not be fully operational until 2032, the security implications are clear – this is to prevent any future Russian land incursion. But Russia’s rail network is not as vulnerable as it seems. Although Russia’s railway lines are long and seemingly unguarded, particularly in the Far East. As the Ukrainians have seen, disrupting traffic for longer than a few days has proven difficult. In part, this is because Russia has a specific railway brigade, an auxiliary wing of the armed forces, which is tasked with the swift repair of its network should it come under attack. The Railway Troops are an important part of the rear. They have been used to resupply the front line in conflicts such as Chechnya and perform an important civilian function during natural disasters by keeping traffic moving. The brigade has evolved over decades to repair damaged tracks at pace, including during warfare, and so Ukraine’s attempts to subvert railway lines and damage bridges tend to only present a temporary stumbling block.
