The station is unstaffed, however the North Cheshire Rail Users Group have "adopted" the station and work on a voluntary basis to keep it looking clean and tidy.[2]
Facilities
Although unstaffed (as noted), the station has a self-service ticket machine (card payments only) 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.[3]
Transport for Wales generally operate an hourly service between Manchester Airport and Chester, with most services continuing to and from Llandudno via Shotton, as well as an hourly service between Liverpool Lime Street and Chester. These services combine to give an off-peak service of two trains per hour in each direction.[4][5]
The station is also served by a limited peak hour Northern Trains service between Chester and Leeds with four trains per day to Chester and five trains per day to Leeds via Manchester Victoria.[4]
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 (May 2019) timetable.
Halton curve
North of Frodsham station, a connecting line to Runcorn (the Halton Curve) diverges. This line was, until September 2018, served by just one "parliamentary" passenger train a week (which operated on summer Saturdays only) 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 (hence the summer-only service requirement). 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. Transport for Wales Rail also run two trains a day from Wrexham General to Liverpool Lime Street with one in the opposite direction. These services were originally planned to start in December 2018; however, this was delayed due to a shortage of available rolling stock.
