stations on the Glasgow Subway network, and has around 1.01 million boardings per year. This is due in part to its situation within the city and also the National Rail network. Partick is a relatively large population centre of Glasgow housing around 100,000 people, a significant number of whom use the subway to commute to the city centre. Furthermore, Partick station is an interchange for two lines on the National Rail network. People commuting from outside Glasgow to one of the areas covered by the underground network may choose to continue their journey from Partick to allow for ease of transfer between the services and to avoid a lengthy walk between (for example) Glasgow Central and St Enoch. It is one of only three with a dual side platform layout (the others being Govan and St Enoch). The rest have either a single central platform covering both circles or two platforms with a track running at the same side of each. The new Partick station replaced Merkland Street, which was located to the south, after modernisation. It should not be confused with the old Partick Cross station which is now known as Kelvinhall and is the next station clockwise from Partick. It is the only station on the Subway that interchanges directly with a railway station, although Buchanan Street is linked to Queen Street by a length of moving walkway. St Enoch once shared this distinction, before its parent St Enoch railway station was closed in the 1960s and demolished in 1977. Partick is one of three subway stations on the SPT Subway line to benefit from mobile telephone service nodes, the others being Buchanan Street and Hillhead. These nodes allow users of the O2 cellular network to use their mobile telephones while waiting on a subway train. The idea was to trial the technology at the busiest stations and, if successful, to put similar devices at each station eventually extending service across the entire network. As yet, the trial is incomplete. The Partick subway station is not wheelchair accessible. The only two Glasgow Subway stations with wheelchair access are Govan and St Enoch, both of which feature a lift and escalator. Aside from Govan and St Enoch, Partick is the only Glasgow Subway station that includes an escalator.
