History

The line began as part of the Selangor Government Railway which opened in 1886. The modern-day Seremban Line began as a spur line, opened in 1895, from the Kuala Lumpur-Klang railway line beginning from Resident station, through the Sultan Street station,^[1] Pudu station and Sungai Besi, before reaching Kajang in 1897.^[2]

The line was later re-routed through Seputeh, with the Sultan Street-Pudu stretch being demolished and incorporated into the LRT Ampang Line. The Rawang–Seremban stretch and the Sentul–Port Klang stretch were electrified in the early 1990s.

Another branch line from Seremban-Port Dickson opened in 1891. The line is also known as a "Zig Zag Line" until in the 1970s. when the few stations has closed. In 2008, the line closed with the branch line undergoing dismantling in 2022.^{[citation needed]}

An infill station, the Kajang 2 station, was constructed between Kajang station and UKM station. It commenced operations on Monday, 13 March 2023, with the official launch of the station done a month later on 14 April 2023 by the Minister of Transport, Anthony Loke.^[3]

Former Seremban-Gemas Shuttle Service

On 1 October 2015, KTMB announced the introduction of the Seremban–Gemas shuttle service for Seremban–Gemas stretch. It was operated by KTM Class 83 trains running the electrified double tracks at speeds up to 140 km/h (87 mph). Spanning over 100 km (62 mi), it served at Seremban, Senawang, Sungai Gadut, Rembau, Pulau Sebang/Tampin, Batang Melaka and ends at Gemas.^[6]

The service offered 59 services daily - 55 services between Seremban and Pulau Sebang and 4 services from Seremban to Gemas. Trains start at 5 am and ends at 11 pm, with a 30-minute frequency. Travel time from Seremban to Pulau Sebang was about 38 minutes while a trip from Seremban to Gemas took approximately 65 minutes.

The service had been operationally effective 10 October 2015 until 11 July 2016, when Seremban Line services to Pulau Sebang/Tampin replaced this shuttle. The shuttle was cut short to Pulau Sebang/Tampin on 20 June 2016; Batang Melaka and Gemas are no longer served by KTM Komuter.

KTM Komuter Trial Route

A new route for KTM Komuter services was introduced for the preparation of the infrastructure upgrading works in the Klang Valley Double Tracking project which began in April 2016. It aimed to increase the frequency and the smooth running of the KTM ETS, KTM Komuter, KTM Intercity & Freight at the Central Sector.^[7] The initial route for from Rawang-Seremban was changed to Batu Caves-Seremban effective 15 December 2015. The line was effectively named the Batu Caves–Pulau Sebang Line.

Additional Service for Early Birds (Bandar Tasik Selatan–KL Sentral-Tanjung Malim)

On 4 August 2016, an additional morning train (Mondays to Fridays except on public holidays) was introduced between Bandar Tasik Selatan, KL Sentral and Tanjung Malim. The train starts at Bandar Tasik Selatan at 5:35 am, running non-stop express to KL Sentral, arriving at 5:49 am. The train then leaves KL Sentral at 6:15 am and runs as a normal Port Klang Line train to Tanjung Malim, stopping at every station before terminating at Tanjung Malim at 7:44 am.^[8]

Service suspension between Putra and the old Kuala Lumpur station

From 22 December 2017, services on the line's three city-centre stations - the old Kuala Lumpur station, Bank Negara and Putra were temporarily suspended due to track upgrading works, though the Port Klang Line continued to serve those stations. Trains only travelled between Tampin and KL Sentral, Batu Caves and Sentul.^[9]

Free shuttle buses, provided by Rapid KL, connected Sentul Komuter station to the Sentul LRT station on the LRT Ampang and Sri Petaling Lines, and KL Sentral. Passengers from the Tampin–KL Sentral stretch could still reach downtown Kuala Lumpur via the LRT Kelana Jaya Line at KL Sentral, the LRT Sri Petaling Line at Bandar Tasik Selatan or the MRT Kajang Line at Kajang and Muzium Negara.^[10][11]

Services have since resumed to their original arrangements.^{[citation needed]}
