If you're doing the community center (the abandoned building near the fountain in the town), the bus is restored when you pay for all the bundles in the vault, the room in the upper right corner. If you can't do anything there, you need to complete other bundles by donating items to unlock it. It does cost a lot of money though.

There's no hurry to get where the bus can take you.

You need to either do the community center, if you've been there already, or become a Joja member (but I would advise against that if you're new to the game). You will come across the option at some point.
You will also need to accomplish a few other goals before it's really worthwhile taking that bus. Have you been to the mines yet?
