Hey has any heard of Vladimir Lenin? He was supposedly a devout Marxist, I recently read some of his works, namely "Materialism and Empirio-criticism" at University. I looked into his background and apparently he was linked to Stalin and Trotsky, two failed Communist revolutionaries after the First Great War. I was wondering if maybe had his train not derailed and he had made it Russia would Stalin and Trotsky's revolution succeeded? What would the Russian Federation look like with a Communist face?
That would have required a much better Swedish railroad system in the 1910s, which is quite hard to get, but inevitable if you wanna avert the Great Norrköping Train Wreck of 1917. That's gonna be pretty tough for you, but shouldn't be impossible.
As for Russia... I dunno actually. There's little to suggest that Lenin would have proven a unifying leader enough to keep the mess that was the 1917 Russian Communist Party from failing miserably at the December Coup. Likely, Kerensky still emerges as a hero from the attempt to destroy the Provisional Government and is still considered the Russian Federation's Founding Father...
If you wanna do this, you're almost gonna have to include Alien Space Bats. For the Bolsheviks, as they were called, to be successful, they need to win the trust of a huge chunk of the people, which is gonna prove
very hard, seeing most Russians firmly favored the Social Revolutionaries. Kerensky is not gonna like seeing the Bolsheviks gain any sense of influence whatsoever, so you'll need some common enemy that the Bolsheviks and the Provisional Government can fight against. Perhaps Lenin, upon arriving in Petrograd, will support the Great War? Or at least agree to help Kerensky fight the Germans...
