Ayrshire Coast Line

The Ayrshire Coast Line is one of the lines within the Strathclyde suburban rail network in Scotland. It has 26 stations and connects the Ayrshire coast to Glasgow. There are three branches, to Largs, Ardrossan Harbour and Ayr, all running into the high level at Glasgow Central.

The route is operated by ScotRail.

History
The Ayrshire Coast Line consists of lines that were formerly part of the Glasgow and Paisley Joint Railway, the Glasgow, Paisley, Kilmarnock and Ayr Railway, the Ardrossan Railway and its Largs Branch extension.

After electrification
The line to Ayr was electrified and Class 318 electric multiple units introduced by British Rail in September 1986. The line was promoted as the AyrLine in Scotrail publicity. Along with the introduction of new trains, major work was undertaken refurbishing stations, major trackworks and rebuilding many bridges. At the same time resignalling was carried out, replacing the existing semaphore signals. The full electrified service, including trains to Largs and Ardrossan Harbour, commenced on 19 January 1987. These were supplemented by occasional use of Class 303 and Class 311 EMUs, then in use on the Inverclyde Line.

These EMUs replaced the Class 101 and Class 107 DMUs that had served the line for over 30 years. Class 126 DMUs were also used on the line, but they succumbed to old age in the early 1980s.

Here the line branches in two, with one branch running south along the coast to Troon and Ayr. This branch also serves Prestwick Airport station, which opened in 1994. The other branch runs north along the coast to Ardrossan or Largs, becoming a single track for passenger trains after Saltcoats. Beyond Ayr, 'Sprinter' DMUs continue south towards Girvan and Stranraer.

The line connects with ferries at Ardrossan to Brodick on the Isle of Arran and at Largs to Great Cumbrae.
