But Putin needs all of that infrastructure to maintain his pipelines that run from Russia through Ukraine to Europe, which is is major source of revenue.
Well, yeah, Putin could easily start bombing power generating plants, power substations, railway lines, and bridges, bringing Ukraine to her knees.

Except he is.
RGF continues to hit bridge SW of Odessa which carries export grain to Romania. That with the destruction of another near by bridge casting fuel, the fuel situation in Ukraine is becoming worse.
RGF has knocked out a fair number of locomotives (rail road ‘stations’) rail yards. This prevent Ukraine from shipping the large quantities of ammo and shells needed at the front as well as interdicting Western weapons.
RGF continues attacks on Ukraine RR system: near Lviv and Carpathian Mountains: Hitting electrical substations for electrical locomotives. Will create even bigger problems with RR infrastructure and RR transportation. Already created significant shortages of fuel. All fuel to UA, little to none to civilians, putting economy even further into total disaster.
