(Reuters) - Blazing trains, damaged tracks and ongoing attacks underline the intensity of the conflict in eastern Ukraine, even as Russia accelerates a major infrastructure build-up across occupied territories, according to analysis and official data.
Ukrainian fighters have repeatedly targeted Russian supply lines, including rail and fuel transport routes in occupied areas.
However, Ukrainian personnel acknowledge that these efforts have had a limited impact on the broader expansion of Russia’s logistics network.
According to Ukrainian military sources, Russia is developing extensive rail and road systems across the occupied regions, strengthening transport links for military and commercial movement.
The Kremlin refers to these territories as “Novorossiya” and has launched long-term infrastructure projects aimed at integrating them more closely with Russia.
These include new rail and highway routes connecting occupied regions with southern Russia and Crimea.
Satellite analysis and official documents indicate that more than 2,500 km of roads and railways have been built, upgraded, or repaired between 2022 and 2025 across occupied territories and adjacent Russian regions.
One key project is a planned rail corridor linking southern Russia with Crimea through occupied areas, alongside a parallel highway network designed to improve troop movement and freight transport.
Work has also been reported on a 630 km highway route connecting key cities in the occupied regions with Russia and Crimea.
Russian authorities have allocated significant funding for transport infrastructure in these areas, with dozens of contracts awarded for road construction, bridge works, and related engineering projects.
Occupied ports on the Sea of Azov, including Mariupol and Berdiansk, have also been reopened and expanded, with dredging and redevelopment work aimed at increasing cargo capacity.
Limited shipping activity has resumed, though levels remain below pre-war volumes.
The infrastructure expansion follows Russia’s annexation claims over parts of eastern and southern Ukraine, including Donetsk, Luhansk, Zaporizhzhia, and Kherson, areas that remain internationally disputed.
Ukrainian officials say the scale and speed of construction mirror earlier development efforts seen in Crimea after its annexation in 2014, but at a faster pace.
Russia has also moved to develop natural resource assets in the occupied regions, including mining and quarry operations, through state-run auctions and contracts.
Ukraine and its Western allies have condemned the integration efforts, saying they amount to illegal occupation and long-term consolidation of seized territory.
The Kremlin maintains that the regions are part of Russia and says infrastructure development is aimed at economic revival and regional integration.
