Malaysia's Express Rail to Johor Bahru Opens a New Chapter as Singapore HSR Remains on Hold

A RM9.5 Billion Upgrade Brings Faster Rail Travel South

Malaysia's RM9.5 billion Gemas–Johor Bahru Electrified Double Tracking Project is completing the final 192 kilometres of the West Coast rail corridor, bringing electric trains closer to a continuous route from Padang Besar on the Thai border to Johor Bahru. The upgrade promises to shorten journeys between Kuala Lumpur Sentral and JB Sentral from as much as seven hours to around 3.5 to 4.5 hours.

As of August 30, 2025, the southern extension is moving through a phased rollout, with the final connection to JB Sentral scheduled for September and officials anticipating operation of the entire line by the end of 2025. Earlier schedules had put full operations in August. The project has therefore reached a major infrastructure milestone while the timetable for bringing all services into operation has continued to change.

The new express rail connection arrives while the proposed Kuala Lumpur–Singapore High-Speed Rail (HSR) remains on hold. Electric Train Service (ETS) trains cannot match the journey of less than two hours promised by HSR, but they offer a practical, less costly alternative for travel along Malaysia's existing railway.

Johor Bahru, described as Malaysia's second largest city and a key economic gateway, stands to gain from faster access to the capital and towns along the route. Singaporean travellers could also benefit when the Johor Bahru–Singapore Rapid Transit System (RTS) Link opens, a development scheduled for January 2027.

For passengers, the immediate change is straightforward: the southern railway is being converted from a single track used by diesel trains into two electrified tracks. The project is intended to make journeys faster and more dependable, create room for more services, and support passenger and freight movement across the peninsula.

What Has Changed Between Gemas and Johor Bahru?

The Gemas–Johor Bahru project modernises the last stretch of Malaysia's West Coast railway that needed this upgrade. Gemas is in Negeri Sembilan, while Johor Bahru sits at the southern tip of Peninsular Malaysia. The 192 kilometre section includes 11 stations, among them Segamat, Kluang, Kulai and JB Sentral.

YTL Construction is delivering the project in partnership with SIPP Rail Sdn Bhd. The government has fully funded the RM9.5 billion initiative as part of its strategy to modernise public transport, support economic growth and improve regional connections.

Double tracking means providing two railway tracks instead of one, increasing the space available for train movements. Electrification replaces reliance on diesel traction with an electric system that includes feeder lines and overhead equipment. Together, the changes allow higher speeds, greater capacity and more reliable services.

The southern extension completes electrification of the West Coast Line from Padang Besar to Johor Bahru. Its importance reaches beyond the two endpoints: towns between them gain access to the same modernised railway, allowing KTMB to consider different combinations of express, intercity and local services.

How the Opening Schedule Has Changed

The project was originally due for completion in 2021. The COVID-19 pandemic disrupted supply chains and workforce availability, while land acquisition problems and technical challenges with electrification pushed the work beyond that deadline.

By late 2024, construction had passed 98% completion. Passenger operations were then planned in stages, bringing electric services progressively farther south before the final extension to Johor Bahru.

• 2021: The original completion deadline was missed as the project encountered pandemic disruption, land acquisition issues and technical challenges.
• Late 2024: Work reached more than 98% completion.
• March 2025: The phased ETS rollout began with services to Segamat.
• April and May 2025: The rollout timetable placed Labis in April and Kluang in May.
• August 2025: An earlier schedule anticipated full operations by this month.
• September 2025: The final extension to JB Sentral was scheduled.
• End of 2025: Officials anticipated that the entire line would be operational.
• January 2027: The Johor Bahru–Singapore RTS Link was scheduled to open.

Transport Minister Anthony Loke Siew Fook has stressed safety and thorough testing. Delays in the Segamat district were linked particularly to checks on electric feeder lines and overhead systems, equipment that must work reliably before regular train operations can proceed.

The September extension and the expectation of full operation by the end of 2025 describe different stages of bringing the railway into service. Passengers planning journeys need to follow the phased opening, rather than assume that the earlier August target covered every part of the route.

How Much Faster Will the Journey Be?

The Kuala Lumpur Sentral–JB Sentral journey previously took up to seven hours on slower diesel trains. Electric express services are expected to cover it in as little as 3.5 to 4.5 hours, saving between 2.5 and 3.5 hours compared with that seven hour journey.

At the shorter end of the projected range, the journey would take half as long. At 4.5 hours, passengers would still spend substantially less time travelling between the two cities. The improvement makes rail a more competitive choice alongside road and air travel.

Trains are expected to operate at speeds of up to 140–160 km/h, with up to 22 daily services. Seating capacity is given as 300–346 passengers per train. Journey times will depend on the service pattern, including how many stations a train serves along the way.

Business travellers could benefit from a direct connection between the two central stations, particularly when comparing the complete trip with flying. Airport transfers and security checks add time beyond the flight itself, making the railway's shorter journey more useful than a simple comparison of train and aircraft speeds suggests.

Leisure passengers are promised a comfortable, scenic and more environmentally friendly journey. The new ETS3 trains include WiFi, USB charging ports and spacious luggage compartments, allowing travellers to work, keep devices charged and carry their belongings during the trip.

Which Services Could Use the Upgraded Line?

Keretapi Tanah Melayu Berhad (KTMB) has an opportunity to rethink the services available on the southern railway. A route with two electrified tracks can support different travel needs, from passengers seeking the fastest journey to people who need a stop in a smaller town.

Three possible service patterns illustrate how the upgraded line could be used:

• Express business class services: Trains running without stops or with limited stops between KL Sentral and JB Sentral, aimed at business travellers seeking speed and comfort.
• Intercity services: Trains calling at major towns such as Seremban, Pulau Sebang in Melaka, Segamat and Kluang, balancing shorter journey times with regional access.
• Commuter rail: Frequent services for daily journeys within Johor, connecting Segamat, Johor Bahru, Pasir Gudang and Tanjung Pelepas, easing road congestion and supporting urban mobility.

Express and intercity services serve different purposes. Fewer stops can help passengers reach the endpoint sooner, while more stops give communities along the line access to the railway. Commuter services would focus on regular local journeys rather than travel between the capital and Johor Bahru.

The project is projected to serve around 3,000 passengers daily on the JB–KL route, with demand expected to grow as the service matures. KTMB has reported strong ticket demand on the new routes, while travellers have welcomed the promised improvements in comfort and efficiency.

Why the Singapore HSR Remains a Different Proposition

The proposed Kuala Lumpur–Singapore HSR promised travel between the two capitals in less than two hours. It has been repeatedly delayed and remains uncertain, with its estimated cost, reportedly above RM60 billion, presenting a major financial obstacle.

Political difficulties, complex land acquisition and questions about viability over the longer term have also affected the HSR proposal. Its future remains unresolved as Malaysia brings the existing southern railway into use.

The Gemas–Johor Bahru upgrade costs RM9.5 billion and is integrated into the national rail system. Using the stated figures, the HSR estimate of more than RM60 billion is over six times the cost of the southern upgrade. The projects have different routes and ambitions: one promises a very fast connection between two capitals, while the other modernises an existing Malaysian corridor.

The express railway offers substantial improvements without reaching HSR speeds. Its government funding and connection to existing tracks make it a practical option for current travel needs, while leaving room for future upgrades if demand and funding support them.

A government official, whose name was not given, described the rationale for the express connection:

The express rail to JB is a practical solution that meets the needs of Malaysians today, while keeping the door open for future upgrades.

For travellers heading to Singapore, the new ETS journey ends in Johor Bahru. The planned RTS Link supplies the next part of that regional connection, rather than extending the express train itself into Singapore.

What the Railway Could Change for Johor

Johor Bahru's role as an economic gateway gives the improved railway importance beyond passenger convenience. Faster connections are expected to support investment, tourism and labour mobility, making it easier for people to travel between Johor, Kuala Lumpur and the towns in between.

Businesses could gain from more dependable transport, while visitors would have another way to reach destinations along the southern corridor. Workers could benefit from a wider range of travel options, particularly if frequent commuter services develop within Johor.

Freight is another part of the project. The upgraded railway is intended to support movement between Port Klang and the Port of Tanjung Pelepas, linking the passenger transport improvements with Malaysia's logistics needs.

The railway is also expected to ease road congestion. The scale of that benefit will depend on how the services develop and how many travellers use them, but the planned mix of express, intercity and commuter trains addresses several types of journey rather than a single market.

Officials expect the completed southern line to act as a catalyst for economic development in Johor and beyond. The projected 3,000 daily passengers on the JB–KL route provide an initial measure of the demand anticipated as the connection enters regular service.

A Royal Launch and New Public Spaces in Kluang

His Majesty the Yang di-Pertuan Agong Sultan Ibrahim personally piloted the inaugural ETS3 train from Kuala Lumpur to Kluang. Transport Minister Anthony Loke and other dignitaries accompanied the King during the journey, giving the launch national prominence.

On arrival in Kluang, Sultan Ibrahim officiated the opening of Laman Rel Mahkota, a public park extending 2.8 kilometres beneath the railway viaduct. The park connects the transport project with a new space for the surrounding community.

The railway upgrade has inspired related developments, including the Kluang Heritage Railway Linear Park. That project aims to create green spaces and promote urban development with lower carbon emissions.

Station openings during the phased rollout have been marked by local events. Public response has been described as overwhelmingly positive, with travellers keen to experience the faster journey and the comfort of the new trains.

Kluang shows how a railway project can affect the places around its tracks as well as the people aboard its trains. Alongside improved transport, the town is gaining public spaces tied to its railway setting.

How the RTS Link Will Connect Singapore Travellers

The Johor Bahru–Singapore RTS Link is scheduled to open by January 2027. It is expected to provide a connection across the border for thousands of daily commuters, shoppers and tourists.

Singaporean travellers would be able to cross into Johor Bahru and then board ETS services at JB Sentral for a direct journey to Kuala Lumpur. The combination offers an alternative to traffic congestion on the Causeway and the transfers involved in airport travel.

The two rail projects address different parts of the journey. ETS strengthens travel within Peninsular Malaysia, while the RTS Link provides the connection between Johor Bahru and Singapore. Used together, they could make the southern corridor easier to navigate for work, shopping and tourism.

The expected gains include stronger ties between Malaysia and Singapore and a more connected economic zone around the border. For passengers, the concrete benefit would be another way to combine an international crossing with onward travel through Malaysia.

The Final Piece of a Wider Rail Programme

The Gemas–Johor Bahru project is described as the final piece of Malaysia's West Coast Rail Electrification Programme, which began in 2011. The wider history of upgrades includes Rawang–Ipoh in 2008, Seremban–Gemas in 2013 and Ipoh–Padang Besar in 2014.

Those earlier sections have already brought benefits through reduced traffic congestion and stronger local economies. Completing the southern section extends the modernised network to Johor Bahru, creating a fully electrified West Coast route from the Thai border.

Malaysia expects the network to strengthen its position in sustainable transport and logistics, support passenger and freight movement, attract further investment and encourage tourism. The railway also provides a foundation for possible future upgrades, including high speed services if demand and funding align.

The delays have shown the practical demands of a project of this scale. Construction depended on land acquisition, workers, supplies and electrical equipment, while opening the line depended on safety tests. Progress continued through pandemic disruption and changing schedules.

The government's decision to continue the EDTP while HSR remained stalled reflects a focus on an existing, funded railway. Resilience, transparency and adaptability have been central to completing the work in phases, with the remaining priority being to bring the entire southern line reliably into operation.
