I love the idea of a heist. On a train? Maybe. But I also love the notion of a payroll heist that necessitates getting into someplace they shouldn't be in the first place. In town? In the Big Bad's stately home? In addition to this, I like the idea of coming to learn a little of the town, what makes BBEG deserve his title. One of my favourite tropes in the lone wanderer / western genre is the notion of anti-heroes coming together to fight on behalf of those who can't fight for themselves. They may have ulterior motives, or have no direct interest in the locals, or in the altruism of 'saving' anyone.

I think the open-ness of a small ville might be > train. Train feels very confined, and western to me feels very open-air (headcanon.) So, option one-ish? Honestly can't go wrong with anything Magificent Seven-esque.
