What Is A Red Line Bus??

Question

I'm On The First Bus Website And It Says Bus From __________ to __________ And It Has At The Top Of It Red Line. And It Has A Small Disabled Icon Underneath It. Some Of The Other Normal Buses Don't Say Red Line But Have A Disabled Icon. So, I'm Guessing Its Not Anything To Do With Disability Passengers. Could It Be The Route? Please Answer Thank-you. 10 Points For Best Answer And A Comment. Thanks xxxxxx
