with or without hsr, singaporean still come to jb and kl regularly. plus with rts commencing next year and sjfz to begin soon. it’s no longer compulsory to come to kl as sg bizmen will focus more on johor. so, there is no need to rush for hsr
My personal opinion, KL Singapore High Speed Rail, should not be built at the moment. We do not have enough commuters between the 2 countries to make the High Speed Rail Profitable. If it is not Profitable, it will be a Financial burden to both Government.
