Bandar Tasik Selatan has become a transportation hub of late with the ERL (Express rail Link), LRT (Light Rail Transit) and KTM Kommuter having a transit station here side by side.
For those who intended to reach KL, there is a shutlle bus to Puduraya Sentral operated by Rapid KL. Otherwise, the best option is to take the ERL, KTM Kommuter or ERL to the intended destination in KL.
The departure hall here reminisce those of an airport. How I wish all our bus stations look like this.
