the Midland Junction to Walkaway line south of Geraldton
Suburban rail service in Perth, Western Australia

The Midland line is a suburban rail service on the Transperth network in Perth, Western Australia. It runs on the Eastern Railway through Perth's eastern suburbs and connects Midland with Perth. Travelling from Midland, the trains terminate at Fremantle on the Fremantle line.

The section of the Eastern Railway between Fremantle, Perth and Guildford was the first suburban railway line in Perth, opening on 1 March 1881. The line was extended from Guildford to Chidlow's Well, opening in March 1884. 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. The third route saw the removal of the Bellevue Railway station in its construction, with the new Midland railway terminus replacing the older Midland Junction railway station. An anomaly of the Midland line timetables in the 1950s and 1960s was that Bellevue was nominally the terminus of the line until 1962. Koongamia, which was a new station prior to Greenmount on the original first route, was the terminus from 1962 to 1966. In 1966, the stations on the first two Eastern Railway routes as well as the old Midland Junction railway station were closed and the new Midland was constructed to the west and became the new terminus. Generally, changes from the 1970s saw a significant number of stations on the line moved or turned into island platform stations (to be compatible with the double track, dual gauge track configuration between East Perth and Midland). On 24 July 2004, Bassendean became the first station to be upgraded under the "Building Better Stations" project. 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. Also, crossings were reduced, and in a number of locations, bridges were constructed.

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. Construction of the Forrestfield–Airport Link commenced in November 2016 and was scheduled to open in 2021. After construction delays it opened on 9 October 2022.

The future Morley–Ellenbrook line, under construction as a branch northward from the Midland line east of Bayswater station, is due for completion in late 2024.

During hot weather, the tracks can distort. As a result, train speeds are reduced by approximately when the air temperature is above , and by an additional when the air temperature is above
The Transperth network currently uses fixed block signalling and automatic train protection, which stops trains that pass a red signal and slows trains that drive too fast. These systems will be replaced by an automatic train control system, likely a communications based train control system. +StationDistance from Perth Fare zoneLocation OpenedConnectionskmmiPerth0.00.01/FTZ (Free transit zone)PerthBus at Perth BusportAustralind, Airport, Armadale, Joondalup, Mandurah and Thornlie linesServices continue on the Fremantle lineMcIver0.70.41/FTZ (Free transit zone)Perth1989Airport, Armadale and Thornlie linesClaisebrook1.30.81/FTZ (Free transit zone)East Perth, Perth1883Airport, Armadale and Thornlie linesEast Perth2.11.31East Perth, Perth1969Airport line, Transwa coaches, MerredinLink, Prospector, and Indian PacificMount Lawley3.22.01Mount Lawley1907Airport lineMaylands4.52.81Maylands1896Airport lineMeltham5.53.41Bayswater1948Airport lineBayswater6.84.21Bayswater1896Bus, Airport lineAshfield9.35.82Ashfield, Bassendean1954Bassendean10.86.72Bassendean1910BusSuccess Hill11.77.32Bassendean1960Guildford12.67.82Guildford1881East Guildford14.18.82Guildford1896Woodbridge15.49.62Woodbridge1903Midland16.110.02Midland1968Bus, AvonLink, MerredinLink, Prospector
