I think you can interpret "and points west" as "and beyond."

I think it's based on the expression "all points west." Can't find a good source at the moment. "Points" is used as a plural noun there, not a verb. So, I think the expression "all points west" means "all locations to the west," and used metaphorically here to mean "all things beyond."

I have heard the phrase "points west" used when listing the places where a train is going. After listing the next several stops, they say "...and points west" to sum up all the stops the train will make that are too far away to be worth listing.

So I guess it's a metaphor for the indefinite beyond that makes sense to people who live on the east coast of the US and ever take the train.
