The Midland line is a suburban rail service on the Transperth network in Perth, Western Australia.

[3] Throughout the 1880s, the Eastern Railway line was extended beyond Guildford and Midland Junction along its first route to Chidlow and Northam.

The second route varied after Bellevue proceeding to Chidlow via the Swan View Tunnel, Parkerville and Stoneville.

In the early decades of the twentieth century, a significant number of rail-crossing accidents between motor vehicles and trains occurred.

Unattended crossings were provided with boom gates, flashing lights and bells to counter inattention or risk taking from drivers.

[citation needed] In December 2013, the Government of Western Australia announced its intention to construct a railway line branching off the Midland line east of Bayswater station to Forrestfield via Perth Airport.
