That sounds like a capital idea.
What are some simple, low-tech methods ?
The simplest is to trash the control boxes. Russian railroads have control boxes on posts everywhere. The electronics in them are all imported from Europe and they can't get more of them. Destroy enough of those and the Russian railroads may grind to a halt. If they don't grind to a halt, it will require all their railroad maintenance people being out there to manually operate the switches on the tracks. If they are going that, they can't be doing their regular job which is keeping maintaining the network.
Back in March a bunch of Belarusian rail workers damaged these boxes in Belarus and it pretty much shut down Russian supply movement into northern Ukraine for a while.
Russians are generally terrible at maintenance, but one thing they do maintain is their rail network and there is a legion of people doing this job year round. Their economy is more dependent on rail than most countries. Take out the rail network and Russia grinds to a halt very quickly.
Another trick to damage a railroad is to remove the fasteners holding the rail to the sleeper on the outside of a curve. As the train goes around the curve, the track will give way and the train will derail.
Russia is also very dependent on cassette bearing made in Sweden and the US for all their rail cars and engines. Since the war began it's estimated about 20% of their rail assets are sidelined because of bearing failures. The bearings use a special steel alloy that China can't make, so they are stuck.
I'm really not super concerned that Putin leaving the political scene in Russia will be a problem. I don't think that a more malign man coming to power was much of a concern for Col. Stauffenberg and the other architects behind operation Valkyrie, either. Even if
Prigozhin is Putin's successor (very unlikely, imo), I doubt he's actually as suicidal as his bluster. One way or another, we'll learn the outcome of succession in the not too distant future.
Like all humans, Putin will inevitably expire someday. When that day arrives, it's uncertain what the future of Russia will be: Will it necessarily collapse? Or will Putin’s successor turn to the West and engage the country in reforms and modernization? Or has Putin already ensured that whoever...

The problem is we won't know for sure if someone like Prigozhin, or whoever replaces Putin has enough restraint or not. From all I've read Putin has had to deal with a pack of warhawks who think the only reason Russia hasn't won this war is because they haven't drafted every male who can hold a gun (except them of course) and Russia hasn't used nuclear weapons. I think it's very likely one of these warhawks will take power if Putin is gone. If Putin is removed in a coup, it will almost certainly be one of the warhawks who replace him.
Putin has been on the world stage for 20 years. At this point he has some idea what the world will tolerate and what it won't. He's only made one really serious miscalculation in his international dealing, and that was invading Ukraine. If Ukraine had collapsed as he believed it would, the west would have been left fuming about his territorial grab, but pretty much helpless to do anything about it.
The FSB was telling him that their agents in Ukraine had undermined the government so badly it would collapse when Russia invaded and there were a lot of Ukrainians who would rise up and join the Russian cause when they crossed the border. The FSB bribed a bunch of Ukrainians who pocketed the money and did nothing in return for the bribe. Their agents were also exaggerating their success in undermining Ukraine.
In any case, Putin normally knows what he can get away with and he skates right up to the line, but doesn't cross it. He's been a master of it all these years until he had one screw up. Most of the warhawks in Russia are fairly provincial in their view of the world. They have little experience of the world outside of Russia and both overestimate Russian abilities and underestimate what the rest of the world can do. They think countries like the US are weak kneed and will cave to pressure from a "real man" Russian.
It's the same thinking that led Japan to attack Pearl Harbor. They thought the US would cut and run if Japan sank their Pacific Fleet. One Japanese who knew American was Yammamoto who was commander of the Combined Fleet and who had been a military attache in the US and had toured US factories. He fully understood what the US was both materially capable of and what the US response would be to an attack. He was shouted down by the rest of the Japanese war planners. In response he said "I will run rampant across the Pacific for six months, and then the rest of the war will be a defensive one as the US pummels our outposts one by one." The Battle of Midway which was the turning point was June 4-7, 1942. Six months after Pearl Harbor.
Stauffenberg wasn't concerned about who would replace Hitler because Stauffenberg was part of a conspiracy who had a plan who was going to replace Hitler. There also wasn't anyone in the German government who thought Hitler was too constrained and holding back. By 1944 the Germans had drafted everyone of draft age and they even had Volkstrum units made up of teenagers who were too young for the draft in most countries and older men who would normally be considered too old. Germany also didn't have any weapons on the shelf they weren't using.
Russia has not fully mobilized and they have nuclear weapons on the shelf. If a Putin replacement decides to fully mobilize before using nuclear weapons, then we might have hope because full mobilization would probably lead to civil war. But if the new leader decided to nuke Ukraine back to the stone age, things could get very messy, and a full nuclear exchange would be possible as an eventual outcome, though I would expect NATO's first response to be conventional.
