railway stations. Cardiff Queen Street is in the east of the centre and is the city's main hub for urban services to the rest of Cardiff, its valleys and the Vale of Glamorgan. Cardiff Central, located in the south of the city centre, is the largest station in the city and one of the busiest in the United Kingdom, focusing on mainline services. Central railway station is located next to Central bus station forming an interchange. Cathays railway station, Grangetown railway station and Ninian Park railway station are all within of the centre serving edges of the city centre. Road The A470 bypasses the centre to the east running southbound to Cardiff Bay and northbound to North Cardiff, Pontypridd, Merthyr Tydfil and Brecon. The A470 road meets the A4232 at Cardiff Bay, leading to Culverhouse Cross and the M4 motorway, and also meets the A48 Carmarthen–Gloucester road at Gabalfa, north of the centre. Some city centre taxis can be hailed. They are usually, but not always, black with a white bonnet or hackney carriages. Water The Cardiff Waterbus has stops at Cardiff Castle and Taff Mead Embankment, next to the Millennium Stadium, with services to Cardiff Bay. Cycle A cycle hire system, similar to those in other large cities, launched in September 2009, and included 70 bikes and 35 hire points (initially 7) around the centre and the south of the city. The cycle hire system was shut down in 2012. In early 2018, Nextbike offered a new cycle hire scheme with docking stations throughout the city.
