== Bus Timetable
- As a bus system operator, I want to add bus stations, so that I can show where all of the buses will go.
- As a bus system operator, I want to add bus lines, so that I can track which lines go to which stations.
- As a bus rider, I want to view a bus line, so that I can see the stations where it stops.
- As a bus rider, I want to view a bus station, so that I can see which buses come to it.
- There's a many-to-many relationship between stations and lines. I'd suggest calling your join table stops.
If you get through these first stories, here are a few more for you:
- As a bus system operator, I want to add buses to a line, so that I can assign each physical bus to a particular line.
- As a bus systems operator, I want to note what time a bus is scheduled to arrive at each stop, so that I can tell my drivers when they should be where.
- As a bus rider, I want to view a bus line and see all of the buses that run on it and what time they arrive at each stop, so that I can pick one that fits my schedule.
- As a bus rider, I want a visual representation of the bus system, so that I can more easily see which lines go where. Hint: Check out D3.js; don't overlook the d3-rails gem.
