The HSR is expected to run up to four times an hour, of which one will be the direct service from Kuala Lumpur to Singapore.

A one-way ticket between the two cities is to cost an estimated S$60-65, which is about three times the cost of a bus trip, but cheaper than budget air travel.

As land management is a state government responsibility, the opposition-controlled government of Selangor can delay land acquisition in and around Kuala Lumpur if it wishes to do so. 

Assuming that 2016 is spent finalising the details, the design and tendering processes will occur in 2017.

If the eventual winners of the bid do not need to raise capital, construction can begin in 2018.

Allowing five years for construction and no delays, services can be expected to begin in 2023-24.
