These locomotives can have four or six axles and there will be an initial firm order for 30 units with deliveries scheduled to start in 2020.

Batch 3 (Super Cargo East) consists of up to 50 six-axle 15kV/25kV ac 5MW locomotives without last mile diesel engines. These locomotives will be certified for operation in Romania, Bulgaria, and Hungary. The locomotives will also be authorised for use in Austria, albeit only on the line between Vienna and the Hungarian border at Hegyeshalom. An initial firm order for 10 units will be delivered from 2017 onwards.

All Super Cargo locomotives need to offer a minimum tractive effort of 450kN and all three batches will have a maximum speed of 120km/h. The contract will include maintenance of the fleet across their entire sphere of operation.
