Don't remember the details, but it's the one with the long-haired blonde that owns the small cabin where they hide some time before. But it's not about that ending in itself being bad, but that all the train part really amounts to nothing, has no impact, develops no new things, gives no new insight in the characters, etc. So when the ending itself came, it felt quick, rushed and could have benefited from taking all those scenes out of it to make longer and better endings (at least IMO).
