The Class 93 is a type of electric multiple unit ordered by Keretapi Tanah Melayu for its intercity Electric Train Service (ETS). A total of 10 sets in 6-car formations have been built and delivered by CSR Zhuzhou of China. As per the technology exchange agreement, part of the consignment shall be partially assembled in Batu Gajah, Malaysia.

The Class 93 ETS will be serving the northern route of the electrified double tracking project (EDTP) expanding upon current ETS rail service beyond Ipoh, to destinations such as Butterworth, Alor Setar, until the Malaysian border station of Padang Besar. Field testing of the KTM Class 93 sets have found that utilizing the present upgraded electrified double track, it is possible for the train to reach Padang Besar from Kuala Lumpur within four hours and fifteen minutes, with 5 stops at hand, while the Kuala Lumpur-Penang leg can be covered within 3 hours.

The rolling stock were to have been put into operation for the launch of the ETS Transit service between Ipoh and Padang Besar and the ETS Ekspres service between KL Sentral and Padang Besar. However, reports of problems during the testing and commissioning of the train sets had resulted in the Malaysian land public transport regulator, SPAD, not approving the trains for use in time for the launch of the two services on 10 July 2015 and 11 July 2015.

The KTM Class 93 is a custom built train engineered to high speed metre gauge operation. Dubbed the "Malaysian Bullet Train", or "Pocket Rocket", it features a streamline sloped head, with better aerodynamic efficiency relative to previous KTM rail classes. It is expected to be one of the fastest trains operating on metre gauge track. Relative to KTM standard meter gauge bogies, special higher strength materials were used in bogie construction. This is done in order to damp and sustain the higher stresses incurred by going at high speed over narrow gauge.
