On any page which is associated with an operator, you have the top tab things don't you 'Timetables', 'Map', 'Vehicles', 'Tickets' etc etc.
Depending on which page you are on, these change. For example if you load the Vehicles tab, 'Map' shows even when no buses are tracking (but on 'timetables' the map tab is removed is no buses are tracking) and on the vehicles page, the tickets tab disappears.
