The 1985 Transport Act deregulated all bus services, except those in London, and obliged Local Authorities to establish private "arm's length" bus companies. Accordingly in October 1986 Cardiff County Council established its own company - Cardiff City Transport Services Limited (trading as Cardiff Bus).
Links with the County Council remain strong. The Council owns all the shares in Cardiff Bus and is represented on the board of directors. As a private company however Cardiff Bus is not permitted to receive subsidies and is expected to make a contribution to its shareholder (the County Council) to recognise the Council's investment in the Company. In order to do this and to compete with other providers of transport, Cardiff Bus has to be run along commercial lines and to be successful. The Transport Act has produced mixed results throughout the country and many long established bus operators have either disappeared or been taken over. At Cardiff Bus a key objective has been to offer stable bus services to the benefit of its passengers, shareholder and employees alike.
Ma Bws Caerdydd wedi bod yn defnyddio'r rheswm "hyd braich" ma dros y blynyddoedd fel rheswm i beidio a cael polisi Cymraeg.
O dan y ddeddf rhyddid Gwybodaith newydd, mae ymgyrchwyr iaith wedi darganfod nad ydi Bws Caerdydd yn dod "hyd lled braich" o'r Cyngor, a'i bod nhw mewn gwirionedd yn dod o dan y Cyngor!
Felly, mae ei polisi iaith nhw yn anghyfreithlon!
Yn y cyfamser mae angen pwyso ar Fws Caerdydd drwy sawl modd -
a) Drwy anfon e-bost / llythyr
b) Drwy ofyn am amserlenni Cymraeg o'r Brif Swyddfa
c) Drwy rhoi glydion 'Ble Mae'r Gymraeg' a phaentio slogannau ar gymaint o arosfannau a phosib.
