East side services ran to Newton, with many extended to via the Clydesdale Junction Railway. The basic service every 30 minutes was Glasgow Central to Neilston via Mount Florida; Central to Motherwell via Mount Florida; Glasgow Central to Kirkhill via Maxwell Park; and Cathcart Circle (Inner and Outer). West Coast Main Line electrification 1974 This included the Hamilton Circle and resulted in east side services terminating at Newton. Peak services from east and west sides operated to Motherwell via Blantyre and Hamilton. Argyle Line opening in 1979 The major change being the extension of west side services from Kirkhill to Newton. Until May 1984 there were four trains an hour on the Newton branch (two via Maxwell Park and two via Queen's Park) and two trains an hour in each direction around the Circle, in addition to the services on the Neilston branch. From May 1984, both the Newton and Neilston services remained 2 per hour, none turned back at Kirkhill and only one ran the full circle each way. 2006/07 Services were operated by First ScotRail, with most services using electric multiple units, although Class 318s and Class 334s (Juniper units) made occasional appearances on the line. 2014 The basic service (Monday to Sunday) is every 30 minutes from Glasgow Central to Neilston via Mount Florida and every hour from Glasgow Central to Newton via Mount Florida, Glasgow Central to Newton via Maxwell Park and the inner and outer Circle service (does not operate on Sundays). This frequency gives a 30-minute service on the west side of the Circle, Neilston and Newton branches, three trains per hour at Cathcart and four trains per hour between Glasgow Central and Mount Florida. These service levels are less than those of the 1960s. At peak times the above services combine to have trains running approximately every 5–10 minutes between Glasgow Central and Cathcart, where line capacity permits. Several trains are formed of the maximum six cars at these times. Commuter levels on this line are quite high and therefore a high density service is required at such busy periods. 2022/23 The line now features a number of different services, however these are considerably reduced from pre-coronavirus levels.
