[6] The first Cardiff trolleybuses were introduced in 1942, their introduction having been delayed by the outbreak of World War II.

Although powers had been obtained to considerably expand the network, a policy U-turn occurred in 1961 when the decision was made to replace all the trolleybuses with motor buses.

[9] Vehicles used on these services are in either an orange or green base livery, and as of July 2017, Capital Links operate seven routes.

[citation needed] The company made a purchase of several battery-electric buses in April 2021 in their effort to modernise their fleet and transform how their network is delivered.

The purchase comes with a successful bid from the Department of Transport to the city's ultra low emission zone scheme.

[11] Cardiff Bus has a turnover of £27million, employs around 705 people, on an average weekday carries around 100,000 passengers.

Adult "Day to go" tickets allowing unlimited travel within each zone are £4.70 for Cardiff and Penarth or £4.60 within Barry.

There are "day to go plus" tickets allowing unlimited travel across the Cardiff Bus network costing £6 for an adult.

Children and Transport for Wales' "My Travel Pass" holders are eligible for discounted fares.

However, since the 1990s the dominant colouring has been green, first with cream lining and since the introduction of modern wrapping, a return for orange in the adjustments/outline.

Just before the introduction of the Iff Card, the company started a "your bus service" campaign, fronted by a series of local people's faces being applied in large scale on the sides and rears of selected buses.

Bus 472 (CN57 FGD) a Scania N270UD Optare Olympus, had a grey vinyl wrapped livery advertising the IFF card following its launch in 2008.

Low fares were achieved by omitting major bus stations avoiding hefty access fees.
