Network Rail’s prototype Class 73/9 Ultra73 locomotive
Two Cummins diesel generator sets supplied by the National Railway Equipment Corporation in America, electronically controlled power conversion equipment, and new electro-pneumatic brakes make up the basis of the new design.
These improvements enable the ‘73/9’ to provide the same power operating under diesel as it does via the third rail, while being cleaner, quieter and more fuel efficient. It also meets the requirements for electromagnetic and signalling compatibility.
Prior to its conversion the locomotive was 73104, and is now numbered 73952.
Class 73s as standard are electro-diesels, capable of 1,500hp under third rail operation and 600hp using their English Electric 4SRKT engines. The rebuilt ‘73/9s’ will use two Cummins QSK19 engines that are capable of 755hp each under both electric and diesel, providing 40% greater fuel efficiency. These engines are also fitted to Class 185s, ‘220/221s’ and ‘222s’.
