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.

It opened in stages from 1888, being extended to Neilston and Newton, giving the Caledonian Railway a fully independent route by 1904. At the Ayrshire end the line duplicated the existing Glasgow and South Western Railway route at a time when bulk coal exports could be handled more economically in Clydebank, so that the primary purpose of the line was short-lived. The Caledonian Railway hoped to develop suburban traffic in south Glasgow where the new line passed through those districts, but street tramcars limited the success of this.

The duplicate routes to Ardrossan were wasteful and, as traffic declined, closures took place from 1930. The eastern section from Neilston and Newton to the Cathcart circle lines developed as outer suburban railways, and were electrified in the 1960s. Those branches, as they became, continue in intensive passenger use at the present day, but are the only remaining sections of the Lanarkshire and Ayrshire line remaining in operation.

Ardrossan Harbour had come to increasing prominence as a coal port by 1880; export coal came largely from Lanarkshire: 84 collieries in the Hamilton area were sending coal to Ardrossan, and the Caledonian Railway was dominant in the coalfield region. However the coal was transported by rail from the pits to Gushetfaulds (in south Glasgow) and handed to the rival Glasgow and South Western Railway (G&SWR) there for onward haulage. If the Caledonian could make a railway to Ardrossan, all of this lucrative traffic would fall to them.

Moreover, the towns in the area, including Saltcoats and Stevenston, as well as Irvine, were of growing importance for industrial activity and serving them would bring further passenger and goods revenue.
