The KTM Komuter Northern Sector (Malay: KTM Komuter Sektor Utara) is one of the five KTM Komuter services run by Malaysian rail operator Keretapi Tanah Melayu. The service was introduced on 11 September 2015 following the completion of the Ipoh-Padang Besar Electrification and Double-Tracking Project in December 2014, which also saw the extension of the ETS service to Padang Besar from Ipoh.
