The original station (signposted solely as "Larne") was sited further west than the current station, on land between Circular Road and Larne Lough by the mouth of the Inver River. This station was a larger affair than the current station, with a through platform, bay platform, signalbox and goods yard, and was opened in on 1 October 1862 by the Carrickfergus & Larne Railway. A small station was also constructed slightly further north by the
Ballymena & Larne Railway on (appropriately) Narrow Gauge Road. Although the narrow-gauge B&LR had a link to allow running to , there was no direct connection to the Irish-gauge C&LR Larne station. Passenger services on the B&LR line ceased in 1933, and the line was closed altogether in 1950. The site of the B&LR station is now buried under the A8 dual carriageway. In the 1970s, road improvement plans necessitated the closure and re-siting of Larne station. A new track alignment was constructed on reclaimed land further out into Larne Lough, diverging from the original C&LR alignment at a point southeast of the original Larne station, and moving back onto the existing Harbour line at what is now Glynnview Avenue. Larne Town was then constructed as a single-platform station on this new alignment with a small ticket office, opening in June 1974 - the suffix "Town" being added at this time to help distinguish it from station. The original Larne station was demolished soon after, and no traces of the original station remain today - the old Circular Road site and the original track alignment are now occupied by various retail units and the local bus station. ==Service==
