KTM Komuter Northern Sector

The KTM Komuter Northern Sector 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.

Currently, the KTM Komuter Northern Sector consists of two routes, namely the Butterworth–Padang Besar route and the Bukit Mertajam–Padang Rengas route. The Bukit Mertajam station acts as the interchange station between the two routes.
