The so-called "tsar train" may serve for the Russian military as a defensive line against future Ukrainian assaults, according to the ISW.
The "Surovikin Line" refers to the massive defensive fortifications built by Russian forces in 2023 on occupied Ukrainian territory.
Ukraine's government has allocated a record UAH 17.5 billion ($466 million) for the construction of engineering and fortification structures aimed at bolstering border defenses. Meanwhile, Estonia, Latvia, and Lithuania have agreed to build anti-mobility defensive installations along their borders with Russia and Belarus.
Furthermore, the government approved a mechanism to distribute an additional UAH 33.4 billion (approx $800 million) in subvention to communities.
Considering that the active frontline extends over a distance of approximately 1,500 kilometers, there is an average of four kilometers of fortifications for each kilometer of the frontline.
