between Motherwell and Glasgow. However, the intermediate calls via Bellshill were soon reinstated, and with the exception of the introduction of several additional weekday peak expresses, this pattern persisted with few alterations until the introduction of a seven-day service in 1997. In 2003, Monday to Saturday services were supplemented with a second train per hour. This saw the existing services diverted to Dalmuir, and the new service travelling to Milngavie, via Holytown, Hamilton Central and Glasgow Central. The arrival of the Alstom Class 334 Juniper EMUs to the SPT fleet in 2002 allowed the last of the elderly Class 303s to be withdrawn and the Class 314s to be cascaded to services on the Cathcart Circle and Inverclyde Lines. For a number of years, Argyle Line services were consequently operated by a combination of Class 334s and BREL Class 318s displaced from services on the Ayrshire Coast Line. However, the Class 334s have mostly been transferred from December 2010 to operate services on the Airdrie–Bathgate rail link, with only occasional services being rostered for these units. The station had some other sporadic passenger services such as two trains a day to/from and two to/from via . 2013-14 Monday to Saturday Daytime 1tph - Lanark to Dalmuir, via Bellshill, Glasgow Central and Yoker 1tph - Lanark to Milngavie, via Hamilton and Glasgow Central Evening 1tph - Lanark to Partick, via Bellshill and Glasgow Central 1tph - Lanark to , via Hamilton and Glasgow Central All Day 6tpd - North Berwick/Newcraighall/Edinburgh to Motherwell/Glasgow Central/Ayr Saturdays Excepted, there are also several peak-hour limited stop services, towards Glasgow in the morning, and towards Lanark in the evening. These limited stop services normally only call at Wishaw, and Motherwell before running non-stop to Glasgow Sunday 1tph - Lanark - Milngavie, via Bellshill and Glasgow Central As part of the £1billion Edinburgh - Glasgow Improvement Project, the Scottish Government intended to introduce an hourly semi-fast service between Glasgow Central and Edinburgh Waverley via Carstairs from December 2013. These proposals would effectively operate as an extension of the existing service from Edinburgh Waverley to North Berwick, with services making intermediate calls at Motherwell, Wishaw, Carluke, Carstairs and Haymarket en route between Glasgow and Edinburgh, providing a journey time of around 65 minutes between Glasgow and Edinburgh. The service began operating at the December 2013 timetable change, but only on sporadic approximately two-hourly frequency at present. The paths
