The current station consists of a single platform.
 An interesting characteristic is how the electric Merseyrail track and the unelectrified Northern track is on the same alignment, with electric and diesel trains using opposite ends of the same platform.
 The line is cut by a large buffer separating the track sections.
Passengers wishing to transfer from an electric train to diesel train walk a dozen yards or so along the same platform to move between trains.
 A similar layout exists at Kirkby station.

Prior to the Beeching Report of 1963 and the subsequent restructuring of the rail network, there were two main through platforms.
The electric Liverpool commuter trains would pull into the southern bay platform.
 This practice ended following the withdrawal of through trains between Liverpool and Preston via this route.
Local services from Preston, East Lancashire & Blackpool towards Liverpool were either withdrawn or terminated at Ormskirk from October 1969 with the last through trains running on 3 May 1970.
From the 4 May 1970, the line was split with all trains using the former Liverpool platform (the Preston-bound platform remains, however is disused).
 The bay platform is now a footpath leading to the bus station.

Only a single Merseyrail 3rd rail electric line runs into the platform, the route towards Liverpool becomes double immediately outside the station.
The line from Ormskirk to Preston has been single track since the summer of 1970, except for a passing loop at Rufford.

The former link between Ormskirk and Southport, via the Burscough Curves, was closed in 1962.
The Skelmersdale Branch has also been lost, having closed to passengers in 1956 and to all traffic seven years later.
It was lifted in 1968, though the Burscough curves remained extant until the mid-1980s.
