I made this page specifically to merge the vibes of The Last of Us with the incredible world of Metro 2033, and I've always felt like my post-collapse hustle would be to set up a walk-through shopping mall in an old train, they are just perfect for that.

Imagine ripping out all the seats and replacing them with shelves, then all the open doors could be an entrance to one little kiosk. You could have weapons in wagon 1, clothes in another, food and entertainment and everything - when you think about it, a single train is enough to house the shopping needs for a pretty large population.
