[6] Initially opened as Keonpark, the station was given its current name of Keon Park on 29 February 1972.

[8] However, the duplicated line converged at the up end of the former Keon Parade level crossing,[9] and it was not until 1988 that the current Platform 2 was provided.

[10][11][12] The crossover, located at the upper end of the station and just past the level crossing, was also provided around this time.

[17][18] It was also around this time that the former City of Preston and former local member for the now abolished District of Reservoir, Jim Simmonds, asked the Victorian Railways for opinions on relocating the station to the up side of the level crossing, to allow better access from nearby residential areas.

The Flinders Street-bound way used the bridge as the Mernda-bound used the level crossing until April 2024, as a solution to keep trains running on the Mernda line.
