TLDR: The double tracking projects which entails signaling to allow the electric trains to ply between Segamat and JB Sentral have been delayed repeatedly over the years. It is expected to cut travel times between Kuala Lumpur and Woodlands, Singapore to 4.5 hours, with only a singular transfer at JB Sentral. Currently, it takes 11 hours to travel the same 371-km route and it requires changing at JB Sentral and Gemas, causing most to choose either flying or taking coaches between the 2 capitals.
