is mainly operated by Class 318s, Class 320s, Class 380s and Class 385s. The Inverclyde line uses the same Glasgow and Paisley Joint Railway tracks as the Ayrshire Coast Line until Paisley Gilmour Street; although the two lines occupy different sets of platforms at Paisley Gilmour Street. From Paisley, the line heads to Port Glasgow station, after which it branches. The main route heads through Greenock to Gourock, where it connects with ferry services to Dunoon and Kilcreggan. The branch heads through the southern suburbs of Greenock to Wemyss Bay, where it connects with ferry services to Rothesay on the island of Bute (From 1 October 2015, for a period of 24 weeks, the ferry to Rothesay left from Gourock. This was due to essential improvement work being carried out at Wemyss Bay linkspan) For most of the day five trains an hour operate each way on the Glasgow to Port Glasgow stretch, four of which run to Gourock, the other serving the Wemyss Bay line. The latter and two of the Gourock trains are express services stopping only at Paisley Gilmour Street and Bishopton (except for the 1725 ex Glasgow, which runs non-stop from Paisley Gilmour Street to Port Glasgow) between Glasgow and Port Glasgow, while the other two Gourock trains stop at all stations. This changes in the evenings, and after 8 pm only two trains an hour run to Gourock, with the Wemyss Bay train stopping at all stations. Proposed link to Glasgow Airport The Glasgow Airport Rail Link to Glasgow Airport would have branched off from the Inverclyde Line near Paisley St. James station. In December 2006, the Scottish Executive gave the final go-ahead for the new link to be constructed; however, the project was subsequently cancelled in September 2009.
