KTM Komuter
On 11 September 2015, Keretapi Tanah Melayu Berhad introduced the Northern Sector KTM Komuter Shuttle (Tren Shuttle KTM Komuter Sektor Utara in Bahasa Malaysia) service between Gurun in Kedah, Butterworth in Pulau Pinang and Kamunting in Perak. This followed the completion of the Ipoh-Padang Besar Electrification and Double-Tracking Project in December 2014. This has since been expanded into the Padang Besar-Butterworth route of the KTM Komuter Northern Sector line.
