The electric trains run between and. Prior to 15 December 2015, the northern terminus of this line was.

KTM Komuter is an electrified commuter train service first introduced in 1995, catering especially to commuters in Kuala Lumpur and the surrounding suburban areas. It is a popular mode of transportation for commuters working in Kuala Lumpur, as they can travel to the city without the hassle of traffic congestion. Coaches are modern and air-conditioned. For those who drive to the stations/halts, 'Park & Ride' facility is provided at a nominal charge.

The line is one of the components of the Klang Valley Integrated Transit System. The line is numbered 2 and coloured red on official transit maps. It was initially named after its current terminus, Port Klang station.

History
The line began as the Selangor Government Railway which connected Bukit Kuda just outside Klang to Kuala Lumpur, opened in September 1886. In 1890 a bridge across the Klang River was constructed, allowing the railway to be re-routed to Bukit Badak and henceforth towards downtown Klang. The line was extended towards Segambut and Rawang in 1892, as a branch line from the Resident station. The railway reached Kuala Kubu Bharu in 1894 and finally Port Klang in 1899.

In 1989 railbus services were offered on the Sentul–Port Klang stretch. The same stretch, along with the Rawang–Seremban stretch, were electrified in the 1990s. Electrification was later extended to Batu Caves in 2009.

During colonial rule, there used to be a branch line from Padang Jawa to Kuala Selangor; the branch line was dismantled between 1931 and 1934.

At present, the Tanjung Malim–Port Klang Line is the oldest existing (and still operational) railway line in the country, taking the title after the Taiping–Port Weld line was dismantled in 1987.

KTM Komuter Trial Route
A new route for KTM Komuter services was introduced in preparation of the infrastructure upgrading works in the Klang Valley Double Tracking project 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.

The original Port Klang Line from Batu Caves-Port Klang route was changed to Rawang-Port Klang effective 15 December 2015.

Former Rawang—Tanjung Malim shuttle service
The KTM Komuter service was expanded to include three new stations beyond Rawang on April 21, 2007, under what was then known as the Rawang-Rasa shuttle service. The stations were Serendah, Batang Kali, and Rasa.

This 22 km stretch was the first portion of the Rawang-Ipoh double tracking and electrification project to become operational. The service was extended to Kuala Kubu Bharu on January 5, 2008. It was further extended to Tanjung Malim on June 1, 2009, and the service was renamed as the Rawang-Tanjung Malim shuttle service.

Until 11 July 2016, passengers had to disembark at Rawang and transfer to the Rawang-Tanjung Malim shuttle service for stations north of Rawang. Service ran at 30 minutes interval. The first and last trains to leave Rawang are at 05:42 and 21:24 while the first and last trains leaving Tanjung Malim are at 05:42 and 21:54. Journey time between Rawang and Tanjung Malim is 45 minutes.

Beginning 12 July 2016, the Rawang-Tanjung Malim shuttle was terminated and was fully integrated into the Port Klang Line as a through service, with trains running all the way to Tanjung Malim. The line was effectively named the Tanjung Malim–Port Klang Line.

KL Sentral–Terminal Skypark Line (Skypark Link)
Since May 2018, a branch line of the Tanjung Malim–Port Klang Line was opened and extended to Terminal Skypark Komuter station that serves the Subang Airport. The line branches off to Subang Airport after Subang Jaya station. The line is served by KTM Komuter's KL Sentral–Terminal Skypark Line (formerly known as Skypark Link), which runs an express Komuter service between KL Sentral and Terminal Skypark, only stopping at Subang Jaya station in between.

The service is currently suspended due to low ridership.

Service suspension at city centre and Segambut stations
Beginning 3 June 2018, Tanjung Malim–Port Klang Line services at three stations in downtown Kuala Lumpur – Putra, Bank Negara and the old Kuala Lumpur station, as well as Segambut were unavailable during off-peak hours, i.e. between 8 am and 6 pm, to facilitate track upgrading services.

For the three city-centre stations - Putra, Bank Negara and Kuala Lumpur, Port Klang-bound trains will serve the stations between 06:30 and 07:50, while Tanjong Malim-bound trains will call at the stations between 17:45 and 19:45.

For Segambut station, only six trains will serve the station everyday: three towards Tanjong Malim in the morning, and three towards Port Klang in the evening. Free shuttle buses on the route KTM3, provided by Rapid KL, provides a link between Segambut station and KL Sentral.

During off-peak hours, trains will only shuttle between KL Sentral and Port Klang, and between Tanjung Malim and Kepong stations only. An hourly shuttle service between Klang and Setia Jaya is also introduced. Passengers can still connect to Kuala Lumpur city centre on the MRT Kajang Line at Muzium Negara, or on the LRT Kelana Jaya Line at Subang Jaya and Abdullah Hukum.

Future infill stations
Construction of Segambut 2 railway station was approved in August 2023, and it is expected to be completed by November 2025. It will be located between Kepong and Segambut stations, near United Point Residence.

An infill station between the old Kuala Lumpur station and Bank Negara station, planned to serve the PDRM headquarters at Bukit Aman, is also being studied.

Rolling stock
The line uses KTM Class 92 trains in 6 car formations.
