The story

Trams

Horse-drawn omnibuses ran in the city from 1845 to 1909 and horse trams from 1872 to 1904. The first tram route ran from High Street in the city centre to the Cardiff Docks and was operated by the Cardiff Tramway Company. In 1898, Cardiff County Borough Council obtained legal powers in an act of Parliament to take over all the tramways in the area and to launch electric trams. The new routes formally opened in May 1902 with the first recorded accident later that month – a collision with a cyclist. More than 23 million passengers were carried in 1904, up from 18 million the previous year. When Cardiff became a city in 1905, 131 electric trams were operating on the network, mainly focusing on the busy Cardiff Docks. In 1928, the network peaked at 142 cars and routes covering 19.5 miles (31.3 km). By 1929, the tram network stretched from Victoria Park in the west, to Grangetown and Cardiff Docks in the south, to Roath and Splott in the east, and to Gabalfa in the north.

The council initially refused to allow motor buses to operate in the city, but reversed this decision in 1910 and operated its own from 1920. 81 tramcars were also introduced by Cardiff Corporation Transport to negotiate the city's low railway bridges. By 1939, these vehicles were becoming worn out and it was decided to phase out tramcars.

Trolleybuses and motor buses

In 1942, trolleybuses began to replace tramcars. The last tram service ran to Whitchurch in February 1950, making it the last place in Britain to commence trolleybus operation after Glasgow. Trolleybus routes were generally the same as tram routes although extensions were made. The furthest and final extension of the network came in 1955, to Ely, where trams had never run. At this point, the system peaked at 79 vehicles and 18 route miles.

In 1959, the Cardiff Corporation Transport (later City of Cardiff Transport) routes, with trolleybus routes in bold, were

Trolleybuses stopped on Wood Street, rather than at Cardiff Central bus station. A full transition to motor buses began in 1962 and was completed by 1970, bringing to an end 68 years of electric traction on the streets of Cardiff. The city has been served by motor buses ever since. Cardiff had the largest municipal bus fleet in South Wales with 253 buses. The fleet of 1960s and 70s maroon and cream double-deckers included AEC Regent V, Daimler Fleetline and Guy Arab V. The company also operated single deckers including AEC Swift.

Other operators

Between the 1960s and 1980s, Cardiff had many small coach operators:

Western Welsh was formed in 1929 and grew to cover an area from St Davids in West Wales to the English border, operating 319 buses in its South Wales fleet by 1970. In 1978 it became National Welsh/Cymru Cenedlaethol which also ran Red & White. The two companies closed in 1992.

Neath & Cardiff's brown and red AEC Reliance fleet operated to towns to the west, to Bridgend, Neath and Swansea in the 1970s. Its coaches were known as 'brown bombers'.

In June 1970, Alan Barrington Smith operated the 59 service from Newport to Cardiff, previously operated by Davies and Baldwin and Red & White, using Bristol vehicles. This route was acquired by Smiths in 1972 and incorporated into their route 31 that circled Newport, but dropping the extension to Cardiff.

CK Coaches Ltd was formed in 1974. In 1981, it gained two routes in the capital, charging lower fares and offering the first competition for the Cardiff municipal fleet within the city since 1927. Leyland buses were bought from London Transport (Daimler Fleetlines) and Leicester City Transport for these routes; one of these was the 54 to Cyncoed, which had a white and orange livery similar to that of Cardiff Bus, but made more use of the white colour. Its blue and white double-deckers served the heavily populated eastern suburb of Llanrumney. CK Coaches later operated a route to Llanedeyrn, and used Wood Street in the city centre rather than the main stands of Central station. The company's licences were revoked on 31 March 1982, ceasing the services.

Falconer and Watts operated tours and excursions, private hire and some contracts from Llanishen, a suburb to the north of Cardiff from 1919 to 1982, when they were taken over by Warners Fairfax of Tewkesbury.

Thomas Motor Services, a Barry-based company, at one time operated the sole bus link between Barry and Cardiff via Dinas Powys. Its Leyland Tigers ran on the route 304 from 1959 until 1970, with Leyland Leopards taking over until 1982. Thomas continued to operate the route using coaches.

Greyhound's fleet consisted of around a dozen coaches in a blue and ivory livery. Some were used for local school contracts, such as at St Teilo's in the Penylan area of Cardiff. Coastal Continental Coach Hire, which ceased trading in 2008, operated Leyland Atlanteans in a red and cream colour on school routes for Ysgol Gyfun Gymraeg Glantaf in Llandaff North.

Local services and operators

Cardiff Bus

Cardiff Bus is the dominant bus operator in Cardiff and also serves Penarth, Sully and Barry. Its network consists of 73 routes, including 8 high school routes, using Scania OmniCity, Yutong E12, Scania N230UD, Fencer f1, Irizar i3, Alexander Dennis Enviro200, Enviro300 and Enviro400 MMC, Mercedes-Benz Citaros 0295 and 0530, and MCV Evora. Cardiff Bus carries 100,000 passengers daily, has a turnover of £27million and employs around 720 people. The fleet and drivers are managed against a timetable using software systems supplied by UK based software supplier Omnibus Systems, which allows the real-time digital information displays positioned at many stops around the city, to inform people when the next bus is due and alerting waiting passengers of any delays. Raised kerbs have been installed at the majority of stops.

In addition to scheduled city buses, Cardiff Bus is contracted to operate some school routes in the city.

A smart card for Cardiff Bus passengers was trialled in spring 2009 and launched as the Iff card in October 2010. In March 2018, Cardiff Bus introduced contactless payment across its services. On the 29th November 2025, the Iff card was removed from use.

In January 2022, Cardiff Bus began to introduce 36 Yutong E12 electric buses to the city, part funded by the UK Department for Transport's ultra-low emissions bus scheme. A further 19 of the same type were introduced in April 2024, bringing the total number of electric buses to 55.

Free b

Free b (Welsh: Bws am ddim Free bus) was a zero-fare shuttle bus that operated in Cardiff city centre, Wales. The route circled the edges of the city centre anti-clockwise. The service was operated by Cardiff Bus.

The service commenced on 12 October 2009 as a response to the creation of a "bus box" in Cardiff city centre. This was formed from the diversion of the terminus of many of Cardiff Bus's services from the Central Bus Station to stops around the edges of the city centre. The shuttle service was introduced to connect these stops, as well as those of Cardiff's four Park and Ride services. The three 28-seater buses in a yellow and black livery were introduced as part of a multimillion-pound joint council and Assembly Government-funded green initiative designed to encourage sustainable transport. Cardiff Council announced that because of low ridership, the Free b bus would be cancelled and replaced with an electric shuttle van. Council-operated electric buggies were introduced in October 2010 in order to carry disabled and elderly passengers around the city centre.

The Free b service followed a circular route that travels anti-clockwise around the city centre linking major bus and rail interchanges. The FreeB operated every 10 minutes until 20:00 on weekdays and until 18:00 on the weekend.

Stagecoach

Stagecoach South Wales, which has its headquarters in Cwmbran, operates routes mainly to the South Wales Valleys from central Cardiff.

It also operates the TrawsCymru T4 between Cardiff and Newtown in the county of Powys in Mid Wales.

Its fleet of over 400 buses is one of the most modern in the country, and includes many low-floor, easy access buses with step-free entrances, dedicated buggy areas and wheelchair access.

It does not issue return tickets. However it issues a megarider pass for all day travel, valid from four weeks until a year. The Cardiff zone stretches to Taffs Well, Creigiau, Castleton and Travellers Rest.

In 2009, Stagecoach launched Wi-Fi on its X4 Cardiff-Hereford ADL/MAN Enviro 300 buses, which are themselves new, replacing older coaches that operated on the route.

Then in 2015, Stagecoach replaced the ADL/MAN Enviro 300's with new ADL/Scania Enviro 300's due to MAN Enviro 300's poor reliability.

First Cymru

First Cymru, the principal operator in South West Wales, operates inter-urban services west of Cardiff, and three services within the city.

They currently operate the TrawsCymru T1C between Cardiff and Aberystwyth in Mid Wales (until April 2018), the X10 Swansea to Cardiff Express (previously called the Greyhound 100) between Cardiff and Swansea, and the Cymru Clipper X2 between Cardiff and Bridgend and Porthcawl.

Newport Bus

Newport Bus, the principal operator in neighbouring Newport, operates an hourly express service between Cardiff, University Hospital of Wales, and Newport. It also operates a non-express service to and from Newport jointly with Cardiff Bus. Like Cardiff Bus, it is a municipal bus company, owned by Newport City Council.

Other bus services

Bus passes

Residents of Cardiff (and Wales) who are over sixty or suffering from certain disabilities, injuries or impediments are entitled to a bus pass enabling free travel across most bus services in Wales. For the Cardiff area, the following buses are exempt from this facility: National Express (including Airport Buses 200, 201 and 202) and Eurolines.

Park and ride

Park and Ride services run every weekend in Cardiff throughout the year. The cost includes bus travel to the City Centre, usually less than many multi-storey car parks. There are four Park and Ride services in the city:

The Park and Ride services are part of Cardiff council's Sustainable Travel City initiative, which is partly funded by the Welsh Assembly Government. There are plans to extend the number of space from 340 to 1,100 due to its sudden increase in usage.

Iff card

Iff card is a contactless smart card introduced by Cardiff Bus in October 2010, allowing customers to travel on its services after having pre-paid. The first 30,000 cards were issued free of charge and pre-loaded with £3 of credit, after which the cards will be charged at £5.

An amount of money is electronically loaded onto the card, either upon boarding a bus or at the Cardiff Bus customer service centre. A passenger then chooses a ticket type. The card can also be used as a season ticket. The card should be topped-up when the balance is low, however the card allows the customer to acquire a negative balance up to £3.

The card can be topped-up in units of £1, £2, £3, £4, £5, £10, £15 and £20 up to maximum amount of £50. The card may be used by persons aged between 6 and 60. The Iff card cannot be used to pay a partial amount. The card would be cancelled if not used for a continuous period of one year
