The original station was opened in 1897. Intercity services were provided for the town from its early years through the 20th century, while KTM Komuter services were introduced in the mid-1990s, when a new station adjoining
Jalan Bukit (
Malay; English: Hill Road) was completed on the east side of the tracks to replace the older station adjoining
Jalan Reko (Reko Road) on the west side of the tracks.
Renovations The KTM ground station has undergone a few remodelings throughout its service. A platform was extended to support Intercity trains that occasionally stretch longer than the station's platform. A second access area for the station was completed and opened for access at the west side of the track in 2004, but has no operational
faregates and had only introduced manual ticketing services from early-2007 onwards. The installation of larger platform canopy roofs was also undertaken during the first half of 2007.
Mass Rapid Transit On 8 July 2011, the final alignment of the MRT Kajang Line was announced with 31 stations; Kajang railway station being one of the interchange stations. Active construction started around August 2012; it was completed and opened to the public on 17 July 2017, along with other Phase 2 stations on the line. This station was the southernmost in the whole of
Rapid KL's rail network until it was surpassed by on 16 March 2023. The MRT construction project included the rebuilding of the KTM station, with new connecting stairwell and redesigned wayfinding sign in similar style to the MRT station. When the overhead platform for KTM commuter was finished, the KTM ticket counter, customer service counter and offices were moved to the Level 1 of the station beside the MRT customer service counter. The on-ground station has since been demolished making Platform 1 no longer directly connected to the station as a side platform. == Bus Services ==
