The National Transport Authority has today announced that a major shake-up of the Dublin Bus network is on the way.
Plans include a new lettering system from A to G which will identify seven 'super-frequent spines' through the city. Numbers will be used to indicate different branches of a spine and buses are expected to travel through every four to eight minutes.

Other changes include a new orbital systems which won't run through the city centre. This is aimed to reduce the need for passengers to travel into town from one suburb and then change to another bus to access another suburb.
