Initially the Conwy Valley line ran into a separate platform on the south side of the station, and a refreshment room was built in 1864. But more space was needed to cope with both main line and branch-line traffic, and on 1 October 1897 the present station was opened on a much larger site, the two island platforms offering six through lines with two bays at each end (a total of four through platforms and four bay platforms). The opening of the new station allowed the demolition of the former station, but also entailed a diverting of the Conwy Valley branch, which now joined the main line some half a mile further east. The old formation was used to store locomotives.
