This article is about 'the television series bridge'. You may be looking for 'the episode'.

The Old Iron Bridge is a bridge that crosses Cattle Creek between Rheneas and Skarloey on the Skarloey Railway. It only appeared in the fifth season episode, Duncan Gets Spooked and made cameos in seasons five and sixth music videos.

On one occasion, Peter Sam's trucks fell into the ravine when he was having a rest. Duncan thought it was funny, and Rusty told both of them a story about the ghost engine who has haunted the bridge ever since it lost control and fell into a ravine.
