KTMB said the discount applies to the KL Sentral-JB Sentral-KL Sentral sector for travel from Dec 12 to Jan 11, 2026.

KTMB chief technical officer Ahmad Nizam Amin said passengers could enjoy the offer by using the “JBBEST” promo code when buying tickets, Bernama reported him as saying in a statement.

He said 5,000 promo codes were available, subject to terms and conditions.

Ahmad said the new train service was timely as it came ahead of the school holiday season and the year-end festive period, when many Malaysians travel to Johor.

Johor residents can also travel more easily to destinations outside the state through the ETS service.

“This facility will enhance domestic mobility and stimulate tourism and business activities in both directions,” he said.

Tickets may be purchased via the KITS Style app, KTMB’s official website at www.ktmb.com.my, or at KTMB kiosk machines.

KTMB said the launching of the ETS service marked the completion of the Gemas-Johor Bahru electric double-tracking project, which covers 192km and has 11 stations.
