Malaysia orders multiple-units with graphene capacitor energy storage

A €180m contract for 22 multiple-units of two types was signed by Malaysia’s Ministry of Transport, national operator KTMB and CRRC Zhuzhou Locomotive on April 11.

The order includes 13 four-car DMUs for use on regional services. These Class 61 units will have an operating speed of 120 km/h, design speed of 140 km/h and be equipped with CRRC’s own design of graphene-based supercapacitor. CRRC said the 60 kF capacity energy storage would enable 85% of the braking energy to be recovered for use when accelerating.
