Expanding on the last post, you could have:-
a) A two line element for the header (bus route & number) with single line element(s) for the next busses.
B) A single line element for the Route/Number, much as now, and double line elements for the next services.
Note that you can, if you wish, use only one of the lines in a two line element, and using a two lines and image can add a bit more interest.
Perhaps the bus number could be an image with a route description following & single line items for the times?
Unfortunately, I can't seem to upload an example from my phone, but could email or post an image from a computer later, if you're interested.
