Technical studies are already underway for the Ringgits 40bn ($US 12.7bn) scheme which involves constructing a 330km standard-gauge from Kuala Lumpur via Seremban, and then following a route via the coastal towns of Melaka, Muar, and Batu Pahat to Johor Bahru, Malaysia's most southerly city, and Singapore.

A maximum speed in excess of 300km/h is envisaged to achieve a journey time of around 90 minutes. This would be highly competitive with air, and much quicker than using the current metre-gauge train service which operates over a 397km route and takes around 7 hours.
