I learned an interesting nugget of information from the 11 bus driver today!
Sometimes the bus destination indicator (right above the windshield) will indicate something other than the normal destination, e.g. “11 ARENA” instead of “11 CANTON”. (See picture)
Confused as to why this might be, I inquired with the driver. I learned that when many buses are running late, system-wide, dispatch can alter their routes so that they give people the opportunity to get downtown, and then get on another bus that isn’t late. Otherwise you’d have busses from the same route running practically on top of each other.
