 The Swanline service itself is regarded as unattractive to users at its current low frequency, with extremely restricted journey to work options for Swansea commuters, but takes up valuable space on the busy section of line between Bridgend and Cardiff.Signalling renewal work in 2007 introduced a new turnback facility at Port Talbot station, intended primarily for turnbacks from the Cardiff direction, but actually capable of use by services in either direction.Owing to very light Swanline passenger loadings, it has been proposed that a more useful service could be offered by abandoning through-running to Cardiff and instead operating Swanline trains between Swansea and Port Talbot only.
