Looks interesting. One minor thing is that if the sorting of the bus lines was numeric rater than lexical I think it would be easier to find a specific bus line. Also the limited lines should be right after the regular lines (like 5L should be right after 5, 9L right after 9), though with a numeric sort this would just be fixed for free.
