The 93 Class is the newest 6 car EMU for ETS services. Manufactured by CSR Zhuzhou Electric Locomotive Co., Ltd., a fleet of 10 sets were ordered, 6 of which were assembled locally in Batu Gajah, Perak, Malaysia.
The northbound and southbound directions are standard between Bukit Mertajam Junction and south of it towards Ipoh, KL Sentral and Gemas. If the train is travelling between the aforementioned stations and Padang Besar via Butterworth, the train will change direction at Butterworth.
Trains travelling through the Bukit Mertajam Bypass ie. not stopping at Bukit Mertajam and Butterworth are most likely not affected.
The train may also, in rare occasions, travel in the opposite direction ie. Coach A at the northbound end and Coach F at the southbound end.
