Millbrook station opened in 1870 when the railway first began operations.

In 1912 the station site was slightly relocated owing to a road widening scheme,[1] and the new facility was built with two platforms, each having buildings, and connected by a footbridge.

The track plan included a passing loop and a short siding.

However, the principal station building, located on the landward platform, has survived, and is currently in use as a cafeteria.

[2] Part of the platform has been restored, and extended using decking, and the cafeteria is themed around its former railway use.
