The Island Line is a railway line on the Isle of Wight, running some from Ryde Pier Head to Shanklin down the eastern side of the island. The line was electrified (630 V DC third rail) in 1967. Trains connect with passenger ferries to Portsmouth Harbour at Ryde Pier Head, and these ferries in turn connect with the rest of the National Rail network. The line also connects to the Isle of Wight Steam Railway, a steam-operated 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.
