Crowds are turning out to examine some of Perth's industrial heritage at the Midland Railway Workshops Heritage Day today.
The free event offers a glimpse inside the most intact example of an early 20th century railway workshop anywhere in Australia.
The Midland Railway Workshops built and maintained steam locomotives, carriages, wagons, tracks, signals and station furniture until 1994, playing a significant role in the social and industrial history of WA.
The open day includes tours, demonstrations of vintage heavy machinery, music performances, mini train rides and other children's entertainment.
Visitors are also able to see how the workshops have been given new life as an artist precinct.
The heritage day runs until 4pm today.
