Location of Western Australian Engineering Heritage Places
From Engineering Heritage Western Australia
To start, type in a city/suburb/street address for your starting location. You can then 'Display Map with all places' for a statewide map of all EHWA places, or limit results to various distances from the starting location. When a map based on various distances is displayed, you can choose between Engineering Heritage Recognition Program (EHRP) places only, or all places for which EHWA has information. On a personal computer, hovering on a place will display summary information for that place. Left click on a place will add that information to the map and include a link for additional information. When clicking on the additional information link, use right click and select 'Open Link in New Tab', you will then be able to return to your map to view additional places. Responses from mobile devices will vary, but a map and place information are still available.

'The majority of the collection is from the WAGR, but there are also items from the timber lines and gold mines that operated in the State as well as private lines such as the Midland Railway Company. The collection spans the whole spectrum of railway history from Katie which was placed in service in 1881 through to more modern diesel locomotives. Bassendean is the administrative centre of Rail Heritage WA.'],
