The first batch of 72 locomotives, numbered BB 63001–BB 63072, were powered by Sulzer 6LDA22B engines developing 440 kW (590 hp). The second batch of 36 locomotives, BB 63073–BB 63108, received the 6LDA22C also rated at 440 kW (590 hp). The third batch was introduced in 1959[2] and consisted of 20 locomotives, BB 63109–BB 63128, had the same engine but uprated to 535 kW (717 hp). The next 87 locomotives, BB 63129–BB 63195, had the 6LDA22D, rated at 535 kW (717 hp). The final batch of 55 locomotives, BB 63196–BB 63250, was introduced in 1962[2] fitted with the 6LDA22E of 550 kW (740 hp). The locomotives were 14.68 m (48.2 ft) long and weighed 64–69 t (63–68 long tons; 71–76 short tons).[1]
