Propped up in her hospital bed, railway conductor Olha Zolotova speaks slowly and quietly as she talks about the day her train was hit by a Russian drone.
When the Shahed [drone] hit I was covered in rubble. I was in the second car. People pulled me out, she says.
My eyes went dark. There was fire everywhere, everything was burning, my hair caught fire a little. I was trapped.
Olha is a victim of Russia's increasingly frequent attacks on the Ukrainian railway system – vital infrastructure that keeps the country moving three and a half years since Moscow's full-scale invasion.
Ukraine's 21,000km-long (13,000-mile) railway system is not merely a mode of transport, it is a central pillar of Ukraine's war effort and a powerful national symbol of resilience.
Olha's injuries were severe, so she was transported more than 300km (185 miles) to a special hospital in the capital, Kyiv, dedicated to railway workers.
Almost every day for the last two months, we have been experiencing targeted attacks on Ukrzaliznytsia infrastructure and on power transmission facilities, says Oleksiy Balesta, a deputy minister at the department that oversees the rail network.
It's a very clear battle for the railways, says Oleksandr Pertsovskyi, chief executive of UZ.
As Ukrainians eye their fourth winter since Russia's full-scale invasion began, UZ's Oleksandr Pertsovskyi believes the attacks on their infrastructure could bring about the hardest winter yet.
But we're not desperate. We're preparing mentally and practically. Ukrainians remain strong in spirit.
