Balaclava station opened on 19 December 1859, when the railway line from
Windsor was extended to
North Brighton. On 3 December 1977, the station was damaged by fire. In 1996, two men found $200,000 in a drum buried beneath one of the platforms. They handed the money in to the
police and the find was reported in the media. In the same week, another man found a second drum under the platform, containing a similar quantity of money, which he also turned in to the police. Because no one claimed it, the men were granted ownership of the money they found, despite being considered trespassers on land owned by the then
Public Transport Corporation. In June 2012, a $13.3 million upgrade to the station was announced. It involved widening the platforms, improving stair and
ramp access, signage, booking office facilities, waiting rooms, wheelchair shelters and toilets, and the provision of new station canopies to increase weather protection.
CCTV cameras were added, as well as provision for future
lifts. In October 2014, construction works were completed, with Balaclava upgraded to a
premium station. Following a
2019 commitment by the
Federal Government, the station was due to receive an upgraded commuter
car-park. However, this was scrapped by the same government in 2021. == Platforms and services ==
