If you want to get from Georgetown in Penang to Arau in Perlis, the only way to easily get there is to take a train operated by KTM (Keretapi Tanah Melayu Berhad).
From Butterworth to Arau, you have to take one of the KTM Komuter (northern commuter) train services (ETS trains no longer operate on this route).
These cheap trains run from the early morning until the evening, with regular services every one to two hours.

(Tambang / Harga Tiket KTM Butterworth ke Arau)
The train fare to Arau from KTM Butterworth is just 9.50 MYR.
As Komuter trains are like subway / Tube trains you get in the west, there is no need to plan ahead and book tickets in advance (like you have to do for ETS trains).
Just go to the ticket counter at Butterworth Station (located upstairs), buy a ticket to Arau, then take the next northbound Komuter train heading towards Padang Besar.
Please note: You can't buy KTM Komuter tickets from the KTM office in Georgetown - This office sells ETS / Intercity tickets only.
