The 160km/h ETCS-equipped locomotives will be authorised to operate in the Czech Republic, Slovakia, Hungary, Poland, Germany and Austria. The first five units will be delivered at the end of this year and Regiojet will receive the remaining three locomotives in 2018.
The locomotives will be equipped to operate on 16.7Hz and 25 kV 50Hz ac and 3kV dc electrification systems.
Regiojet has also placed an order with Romanian rolling stock manufacturer Astra Vagoane Calatori for another 16 inter-city coaches, supplementing the 10 it has already supplied.
The new coaches will be equipped with leather seats and an entertainment system with screens in the seat backs. Each coach will seat 80 passengers.
Deliveries are due to be completed before the end of the year.
