The buses in Ankara are dependable and the routes are extensive. There are two different types of buses and the difference is in how you pay. The buses that have red numbers will only take cash. When you get on, there will be a man in the middle of the bus taking money and giving transfers. The buses with the blue numbers will only take an EGO card and will not take money. These buses will require you to have your card ready to pay when you get on the bus.
