The Southern Shuttle service in Johor Baru is currently utilizing diesel trains as an interim solution while awaiting the delivery of new Electric Multiple Unit (EMU) train sets. Transport Minister Anthony Loke stated that the government opted for this immediate deployment to provide commuters with travel options rather than waiting two to three years for new electric rolling stock.
Why is the Southern Shuttle using diesel trains?
The decision to deploy diesel trains serves as a stopgap measure to address immediate transit demand in Johor. According to Transport Minister Anthony Loke, the alternative would have been a multi-year delay in service availability. The current rolling stock allows for the immediate operation of routes linking Kulai, JB Sentral, and Pasir Gudang. These diesel units are scheduled to be phased out once the Gemas-Johor Bahru electrified double-tracking project reaches completion, at which point the line will transition to the Electric Train Service (ETS).
The Kempas Baru-Pasir Gudang route has been opened to passenger traffic for the first time. Previously, this specific line was restricted exclusively to freight services, marking a significant shift in regional rail utility.
How does the current service impact travel times?
Rail travel on the Southern Shuttle offers a faster alternative to traditional road-based commuting in the region. Based on official project data, the journey between Kulai and JB Sentral takes approximately 40 minutes. Additionally, the route connecting Kempas Baru and Pasir Gudang is estimated at 40 to 45 minutes. These transit times provide a benchmark for regional connectivity as the infrastructure continues to develop toward full electrification.

What are the primary criticisms of the current rollout?
Public feedback regarding the Southern Shuttle has focused on the cost-to-service ratio. According to reports from Bernama, some critics have raised concerns that the fares for the diesel-powered service are three times higher than comparable rail services in Kuala Lumpur and Seremban. While the Ministry of Transport maintains that the service provides necessary convenience, these pricing concerns highlight the tension between immediate service availability and long-term infrastructure affordability.

Future outlook for Johor’s rail infrastructure
The long-term strategy for rail in Johor hinges on the completion of the Gemas-Johor Bahru electrified double-tracking project. Once finished, the reliance on diesel-powered shuttle services will end. The transition to the ETS is expected to standardize service quality across the southern corridor, aligning it with the electrified standards seen in other parts of the peninsula. This upgrade is intended to increase both the speed and the comfort of travel for daily commuters.
