"The RENFE Series 333 are high power six-axle diesel-electric locomotives built in the 1970s; at the time of their introduction they were the most powerful non-electric locomotives in Spain.After three decades of service the class were rebuilt incorporating Alstom's newer technology, and thus extending their life - these rebuilt machines were given the sub-class names 333.3 and 333.4"@en .
