Riding the bus in Tucson I have found an interesting trend, different buses used on different routes can be very different. While this may not be surprising to some, I found it interesting. I won't make a comment about why the difference, but give what I perceive as the situation.
So I have been riding the bus from where I live on the East side to the University. I just happen to live where it is actually convenient for me to take the bus, which is not true for all parts of town. Convenient to me are the number 4 bus that goes down Speedway, the number 5 bus that goes down Pima Street, and the number 109X (X for express) bus that goes down Grand Boulevard.
The number 4 bus goes down Speedway, a very popular route. This is usually an older bus, with benches for most of the seating. This bus is always crowded.
The number 5 bus runs from PCC West down Speedway, turns up Tucson Blvd and then turns down Pima when heading east. This bus has bench seating for half the bus. Since this bus goes by Catalina High, at times this bus is crowded with students.
The 109x goes down Speedway past the UofA and then North on Columbus, at Grant it starts heading east. This is an express bus so has fewer stops. This bus has only one set of bench seating in the front. Since this an express bus it costs 25 cents more to ride.
