Newport (Welsh: Gorsaf Rheilffordd Casnewydd) is the second-busiest railway station in Wales (after Cardiff Central).

[2] The station was originally opened in 1850 by the South Wales Railway Company and was greatly expanded in 1928.

A new station building was built in 2010, with four full size platforms to facilitate new Great Western Railway 10-car Intercity Express Programme trains.

As at February 2019, the station is a calling point for GWR (who provide most of the services), as well as Transport for Wales Rail and CrossCountry.

In December 2022, the ORR approved Grand Union to commence a new service from Paddington to Carmarthen in partnership with Spanish rail operator Renfe, for which a fleet of new bi-mode trains will be used.

[4] The service will call at Bristol Parkway, Severn Tunnel Junction, Newport, Cardiff Central, Gowerton and Llanelli en-route to Carmarthen.

To address this the former loading dock on the north side of the station was made into a passenger platform (No.

Subsequent removal of the scissors crossovers saw a further combination and renumbering of platforms to the current layout.

[13] Printed tickets and National Rail enquiries use the suffix "South Wales" to differentiate this station from its namesake in Essex.

The waiting room and customer toilets are situated between platforms 2 and 3, as is the Upper Crust café.

In the booking hall there is also a small buffet, telephones, automatic ticket machines and a photo booth.

The plans also included an extended platform 4 capable of accommodating up to twelve-carriage intercity trains and a new multi-storey car park for long-stay travellers.

The initial redevelopment of Platform 4 did not allow for disabled access, resulting in station staff using a locally contracted taxi firm at £3 a passenger to move disabled and elderly passengers the half-mile from one side of the station to the other, in a complimentary service provision.

The new bridge is clad in ethylene tetrafluoroethylene (ETFE),[18] the material which protects the Eden Project in Cornwall.

[20] The development was criticised by RAIL magazine columnist Barry Doe for being at the wrong end of the station, a lack of seating and generally poor design.

[22] Arriva Trains Wales had expressed concern about a leaking roof, an inadequate customer service area and insufficient ticket gates.
