TL;DR – For now only, we hope.
While there are many ways we could travel from Singapore to Johor Bahru, we all know that the fastest way to getting to Johor Bahru would be via the shuttle train service is run by KTM Berhad and called Shuttle Tebrau.
Since its launch on 1 July 2015, this train service has made life easier for frequent JB-goers as the Shuttle Tebrau transports passengers across the Causeway in only 5 minutes.
Unfortunately, that might not be the case at the moment (at least).
According to Railtravel Station, as of 1 October 2018, KTM Berhad has launched its new ticketing system called the KTM Shuttle Tebrau, and this new system will be “faster and easier for the passengers”.
However, this new Shuttle Tebrau ticketing system will only accept payment via Malaysian internet banking.
In other words, from 7 October 2019 onwards, Singaporeans and other nationalities will not be able to purchase Shuttle Tebrau tickets online without a personal Malaysian internet banking account – unless you have a Malaysian internet banking account and/or Malaysian debit card.
Alternatively, if you are itching to go to JB, you can still purchase your tickets from the ticketing counters at Woodlands Train Checkpoint in Singapore.
