Chelsea station opened on 4 February 1907 The name was suggested by local farmer Bertha Black, whose mother was originally from Chelsea. The
interlocked frame was also abolished at this time, replaced by a
control panel within the former
signal box. In 1984, the
overhead wire for a
siding at the station was removed and, in 1987, the siding was abolished. In 2004, a
crossover that was located at the
Frankston end of the station was abolished. As part of the 2010/11
State Budget, $83.7 million was allocated to upgrade Chelsea to a
premium station, along with nineteen others. However, in March 2011, this was scrapped by the
Baillieu Government. The station was rebuilt, and the Chelsea Road level crossing removed, as part of the
Level Crossing Removal Project In 2020, construction started and, on 25 July 2021, the station was closed for demolition. On 22 November of that year, the rebuilt station opened to passengers, along with nearby
Edithvale and
Bonbeach. The line was rebuilt below in a
trench, with the level crossing permanently closed to road vehicles, and nearby Thames Promenade extended to the
Nepean Highway. ==Platforms and services==
