Although unstaffed, the station has a self-service ticket machine to allow intending passengers to buy before boarding or to collect pre-paid tickets. Train running information is provided by CIS displays, timetable posters and a pay phone. Waiting shelters are also provided on both sides. Step-free access is available to both platforms, although the footbridge between them has stairs.
Services
The station is served by an hourly Transport for Wales service to Manchester Airport via Warrington Bank Quay and an hourly service to Liverpool Lime Street. In the other direction, services run to Chester, with trains from Manchester often continuing along the North Wales Coast Line as far as Llandudno, while trains from Liverpool currently terminate at Chester save for a single service to Wrexham on weekday and Saturday evenings. On Sundays trains only run between Manchester and Chester and Liverpool and Chester. Frodsham is also served by the infrequent Northern Trains-operated service between Leeds and Ellesmere Port. This does not run on Saturdays and Sundays.
Expansion of services
Northern's planned Leeds - Manchester Victoria - Chester service stops here since its launch in May 2019, though only at weekday peak times in the current timetable.
Halton curve
North of Frodsham station, a connecting line to Runcorn diverges. This line was, until September 2018, served by just one "parliamentary"passenger train a week to fulfil legal and contractual obligations and keep the line "open" in accordance with Government legislation. The curve had lost its regular service in May 1975, but continued to be used by seasonal passenger trains between Liverpool Lime Street and Llandudno until 1994. The train started from Chester and ran non-stop to Runcorn, passing through Frodsham without calling. In May 2019 regular service was reintroduced between Liverpool Lime Street and Chester, via Runcorn, with one train per hour every day. TfW Rail also run two trains a day from Wrexham General to Liverpool Lime Street with one in the opposite direction. These services where originally planned to start in December 2018, however this was delayed due to a shortage of available rolling stock.
