The Island Line is a railway line on the Isle of Wight which runs along the island's east coast and links Ryde Pier Head with Shanklin. Trains connect at Ryde Pier Head with passenger ferries to Portsmouth Harbour, and these ferries in turn connect with the rest of the National Rail network via the Portsmouth Direct Line. The line also connects to the Isle of Wight Steam Railway, a heritage railway, at Smallbrook Junction. For much of its length the line runs alongside the A3055, criss-crossing this road by means of the Ryde Tunnel and bridges at Rowborough, Morton Common, Lake Hill and Littlestairs.

Ryde Pier Head railway station is one of three stations in the town of Ryde on the Isle of Wight. Situated at the end of the town's pier, it is adjacent to the terminal for the Wightlink fast catamaran service connecting the island with Portsmouth on the English mainland. Passengers can use this to connect with the rest of the National Rail network at Portsmouth Harbour station, which is adjacent to the Portsmouth terminal. Through rail tickets for travel via Pier Head station are available to and from other stations on the Isle of Wight. These include travel on the catamaran service to or from Portsmouth as appropriate.
