"Railway transformer substations on Russian territory are relatively easy targets, the destruction of which will bring a tangible effect. Russia uses electric traction on the railway to supply the front. Therefore, disabling transformers will cause delays and force the enemy to switch to diesel locomotives, seriously complicating logistics," the Defense Express analysts noted.
Meet “Liutyi,” Ukraine’s homegrown drone behind strikes on Russian oil refineriesOSINT researchers from the "Oko Gora" community emphasize that the Ukrainian drones targeted a lateral railway line crucial for enemy troops in the mentioned regions. The use of strike UAVs to hit enemy railways is considered even more interesting and unexpected than the attacks on Russian oil refineries. Traction or transformer substations on railways are even more compact targets than, for example, a primary oil refining unit at any Russian refinery. Consequently, striking these elements of railway infrastructure requires even higher precision.
