The wooden railway bridge at Eltham, on Melbourne’s suburban Hurstbridge line, is the last surviving wooden bridge on the Victorian railway network. While other wooden bridges do still exist carrying trains on heritage lines, the one at Eltham is the only one still carrying regular trains on the main state system.
This video explains why the bridge still exists, as well as going over some of its interesting physical features. The bridge was originally built when the line opened in 1902 and was electrified in 1923. Today it carries about 120 six-car electric suburban trains every weekday, and almost as many on weekends. The current operator is Metro Trains Melbourne, and all trains on the Hurstbridge line are currently Alstom X’trapolis sets.
