The line runs from the north at Padang Besar, near the border with Thailand, to Gemas in Negeri Sembilan.

The ETS covers the section of the West Coast Main Line between Padang Besar near the Malaysia-Thailand border and Gemas near the border between Negeri Sembilan and Johor, including the branch line between Bukit Mertajam Junction and Butterworth.

Most routes originate from KL Sentral, the main railway station of Kuala Lumpur, the capital city of Malaysia.

As of 2020, due to traveling restrictions and efforts to curb the pandemic, there were only two trips per day along the five routes that are currently under operation.

These new services offer faster travel, with trains only stopping at major stations along the West Coast Line.

These new services came after the completion of Phase 1 of the Klang Valley Double Track and Electrification (KDVT) Project.

Linkbridge access to the Padang Besar Immigration, Customs, Quarantine and Security (ICQS) Complex.

Serving passengers who are mainly students of Universiti Tunku Abdul Rahman (UTAR) Kampar campus.

Railway services continue to Johor Bahru Sentral and Tumpat via KTM Intercity.

Terminus for the KTM Komuter Northern Sector Butterworth-Ipoh and Padang Besar-Butterworth Lines.

Its inaugural run was celebrated with an opening ceremony at Kuala Lumpur railway station.

On the following day, 11 July 2015, a new service called the ETS Ekspres between KL Sentral and Padang Besar, via Butterworth was introduced, which only stops at 15 stations.

However, this service was subsequently reduced in frequency and ultimately terminated with the introduction of the new KTM Komuter Northern Sector.

The train sets were designed by the Marubeni Corporation and jointly built by Hyundai Rotem of South Korea and Mitsubishi Electric of Japan.

A batch of 10 Class 94 trains was tendered in May 2020 in light of the completion of the Gemas-JB Sentral Electrified Double Track Project (EDTP).

The ETS trains currently travel up to 140 km/h (87 mph) on the electrified metre gauge rail line.

Thus, the ETS stands as one of the fastest 1,000 mm (3 ft 3+3⁄8 in) metre gauge train services in the world, reaching a maximum speed of 140 km/h (87 mph).

The seats are arranged in a 2+1 configuration, offering greater width and the ability to recline up to 45 degrees.

Each seat is equipped with both a power outlet and a USB port, as well as an on-demand video screen for in-train entertainment.

The MYR 8 billion contract was expected to be tendered by the end of 2008, pending a mid-term review of the Ninth Malaysia Plan.

In May 2009, Global Rail Sdn Bhd, a relatively small contractor, and its Chinese partner, China Infraglobe, submitted a proposal to the Government to build and upgrade tracks from Gemas to Johor Bahru at a cost of MYR 5 billion.

[20] On 29 January 2011, then Transport Minister Datuk Seri Kong Cho Ha stated that the Gemas - Johor Bahru double-tracking and electrification project was expected to start that year.

He added that the Government hoped to appoint the contractor for the project within the year and that Malaysia was still in discussions with China Railway Construction, though nothing was confirmed.

[21] On 27 October 2015, the public display exercise, required for all new railway developments under Section 84 of Malaysia's Land Public Transport Act 2010, for the Gemas - Johor Bahru Electrification and Double Tracking Project began and ran until 27 January 2016.
