"Based on feedback, we do not foresee any disruption to the train services."

The official said there had also been no reports of cancellation of tickets by passengers.

The southern province of Songkhla is reported to be stable.

The border towns -- Danok near Bukit Kayu Hitam in Kedah, Pekan Siam at Padang Besar and Wang Kelian-Wang Prachan -- are calm.

The Malaysian consulate in Songkhla said it was business as usual there.

"Songkhla and all the border towns are free from violence and protests.

"The people here are more interested in business. They are far away from the political scene.

"Malaysians travel across the border freely without any signs of a high-security alert."

There are 150 to 300 Malaysians who work and live in Songkhla.
