Background and Design
The class could be described as the bigger and better version of the RENFE Class 352, being similar in design, and from the same builder, but with more power and also two cabins to simplify operation.
They were delivered between 1968 and 1969, built to a similar two-engined hydraulic transmission design as the Class 352 but with Maybach 12-cylinder engine developing more power, 1,500 hp (1,100 kW) (at 1600 rpm) each, giving a tractive effort of 268 kN (60,000 lbf). Built with two interior walkways via the cabins, the locomotives were a little heavier than their predecessors at 88 t (87 long tons; 97 short tons).
The locomotives were fitted with coupling screws and Scharfenberg couplers. Auxiliary generators provide electrical power for the coaches.
Two sets of standard gauge bogies were also supplied, for cross border work (bogie exchange).
The locomotives were painted in red-silver.

“I had many problems in my conduct of the office being contrasted with President Kennedy’s conduct in the office, with my manner of dealing with things and his manner, with my accent and his accent, with my background and his background. He was a great public hero, and anything I did that someone didn’t approve of, they would always feel that President Kennedy wouldn’t have done that.”
—Lyndon Baines Johnson (1908–1973)
“... every experience in life enriches one’s background and should teach valuable lessons.”
—Mary Barnett Gilson (1877–?)
“If I commit suicide, it will not be to destroy myself but to put myself back together again. Suicide will be for me only one means of violently reconquering myself, of brutally invading my being, of anticipating the unpredictable approaches of God. By suicide, I reintroduce my design in nature, I shall for the first time give things the shape of my will.”
—Antonin Artaud (1896–1948)
