Ukraine is carrying out strikes on Russia's railways, the acting governor of Bryansk Oblast says. Yegor Kovalchuk claims that Ukrainian drones collapsed part of a bridge and derailed dozens of rail cars across the region, in a post on Telegram.

Bryansk is the main launchpad for Russia's drone and ballistic strikes on Kyiv and on the Chernihiv and Sumy oblasts, and its lines likely carry supplies that feed those attacks. For nearly a month, Russian jet-powered drones have been striking Kyiv from the region.

Kovalchuk reports damage in three districts but adds that no one was hurt in those drone attacks.

The launchpad's railways take hits

On the Dyatkovo–Lyudinovo line, a drone attack brought down part of a bridge and derailed 10 cars, Kovalchuk says. In the Unecha district, 18 empty gondola cars derailed. In the Navlia district, a strike damaged the track without stopping trains.

Repairs will begin, he notes, once the National Guard has inspected the sites.

Russia's campaign dwarfs it

Ukraine's strikes on Bryansk are modest beside what Russia is doing to Ukraine's railways. In the first eight months of 2026, Ukraine's state operator logged more than 1,600 attacks on its rolling stock and infrastructure, Oleh Holovashchenko of Ukrzaliznytsia tells DW.

Russia has damaged more than 500 locomotives since the invasion, over half of them this year, and has increasingly hunted moving trains to sever the corridors that carry Ukraine's exports and supplies.

A drone finds a train near Poland

The campaign even reaches Ukraine's western edge. On 13 September, a Russian jet Geran struck the locomotive of a passenger train at the Yahodyn crossing in Volyn, two kilometers from the Polish border.

A dispatcher spotted the drone in time to evacuate the passengers, among them former CIA director David Petraeus, and a diplomatic train carrying former British prime minister Boris Johnson had left early.

Ukrainian partisans say they have sabotaged the railway signaling that keeps Russian troops supplied on the Lyman front. The ATESH movement reports that its agents disabled four relay cabinets on a line through Voronezh Oblast that carries military cargo to Russian forces there, delaying ammunition to three regiments.

The strike was timed to help Ukraine's Operation Vivaldi, the counteroffensive the Third Army Corps is running near Lyman in northern Donetsk. In its first phase, the operation cleared 75 square kilometers of Russian infiltrators and de-occupied another 10.

Cutting the rail line that feeds the Russian units facing that offensive is, by ATESH's account, part of the same fight, targeting the supply line rather than the front.

Four cabinets go dark

The sabotage hit a rail corridor running through the Voronezh, Novovoronezh, Liski, and Ostrogozhsk areas of Voronezh Oblast, a route ATESH says Russia uses to move military cargo toward the Lyman axis.

Relay cabinets house the switching gear that runs a line's automatic signals. Knocking them out can freeze traffic on a stretch of track without a single explosion, and ATESH says its agents disabled four of them. As with the movement's other claims, the account could not be independently verified.

Ammunition backs up

By ATESH's telling, the signaling failure delayed shipments of ammunition and engineering materiel to the 1st and 15th Guards regiments and the 254th Motor Rifle Regiment. Russian commanders, it said, had to rush in repair crews and divert resources to guard the infrastructure. A delayed shipment, far behind the front, can be felt at it, where an assaulted position waits for the ammunition that does not arrive.

ATESH hunts the supply lines

ATESH is a network of pro-Ukrainian agents operating inside Russia and Russian-occupied territory, and it has increasingly gone after the rail and power infrastructure that sustains Moscow's war. This month, the group also said it knocked out the power supply of a plant in Voronezh that makes components for Russian missiles.
