History
The lines were built by the
Cathcart District Railway (Cathcart Circle) and the
Lanarkshire and Ayrshire Railway
The Lanarkshire and Ayrshire Railway (L&AR) was an independent railway company built to provide the Caledonian Railway with a shorter route for mineral traffic from the coalfields of Lanarkshire to Ardrossan Harbour, in Scotland.

(Newton and Neilston lines). The first part opened on 1 March 1886 as a double line from Glasgow Central to then single to Cathcart, doubled on 26 May 1886. The circular route back to Central station via
Shawlands and Maxwell Park was completed on 2 April 1894.
The Newton and Neilston branches were built to provide a through route from the
Lanarkshire

.
When the lines were built much of the land around them was open countryside. The existence of a commuter railway was a major factor in the development of Glasgow's southern suburbs, although until electrification in 1962 there was virtually no passenger service beyond Kirkhill by this route.
On weekdays the services have provided a vital transport link for school pupils and college students at nearby schools and higher education establishments, contributing to passenger numbers on top of the commuter traffic.

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).

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.

in 1986, they made occasional trips onto the Circle. The Class 311 were withdrawn in 1990, and following the introduction of the the Class 303 were withdrawn in 2002 and a major redeployment of the fleet took place, resulting in the
Class 314s taking over the line, supplemented occasionally by Classes 318 and 334.
In 2014
Class 314s primarily operated the Circle (including
Newton,
Neilston services). During peak hours
Class 380s are also used on the Circle route only.

Glasgow to Edinburgh via Falkirk High route. From the December 2018 timetable change, Class 380s began operating most Neilston services, along with some Circle an Newton services. From February 2019,
Class 385s began operating some Circle and Newton services.

's Strategic Transport Projects Review suggested an upgrade of the Circle to light rail as part of a wider light rail network for Glasgow, incorporating both new lines and re-purposed older alignments.
If taken forward, this proposal was supposed to have been implemented during the period 2012 - 2022, in line with the scope of the strategic review.
Glasgow Metro
The Cathcart Circle has been identified as one of the heavy rail lines that would be converted to metro as part of the proposals for the Glasgow Metro project. No timescale or budget has been released so far, but it is anticipated that it would be one of the first metro lines given that most of the infrastructure is already in place.
