Sup /lit/, i decided to write a short story (or probably several of them) inspired by the book "Darkness" by Ondřej Neff, original book is happening in 1998+, "it is 17. April 1998 and electricity sudenly "stopped working" because of switch between the Northern and Southern Earth's magnetic field, entire country/world is in chaos, government is trying to save everything, warlords are everyhwere.
My story would be in 2017/2018 (iam not sure yet) about the young railway worker Tomáš Vrána that work on the Bohumín train station. (that has very strategic position and is going to be very powerful in the future), Tomáš has friend Jan Podhorský (that is inspired by my 47 years old friend from Prague i used to play DayZ with, he is basically Centurion Macro from the Scarrow´s Eagle series.)
I already have the story, how things will work, how politics between the warlord city states will work etc. My only problem is that i dont realy know much about how do railways work, how things will be organized without the elecricity (good thing is that i can copy the idea about the steam and diesel trains from the original book. I think it should start like "Hey, young (the way how do old guys refer to their younger co-workers, Macro also calls Cato like that in Czech translation) electricity is out." "What boss?" "Elecricity is fucking out! Nothing works, not just a fucking circuit breakers, i think something happened to the power plant." This would be followed by something like Tomáš hearing crashes of cars and yelling of the people (cars dont work as well), at the end of the day, military from the local garrison in Ostrva would came. In original book, railway workers became extremely powerful, so iam going to extend the storyline that way.

So what do you think? Is it a good way how to start? Or is there something better?
(Iam not writing the story in English, thanks God.)
