Renfe Class 319 (later versions)

The Renfe classes 319.2, 319.3 and 319.4 are six axle Co'Co' medium power mainline diesel-electric locomotives manufactured by Macosa using General Motors Electromotive division components under license.

In the 1980s the company started to upgrade its diesel fleet; the original class 319s began to be scrapped and a new version, twenty of which, were constructed, forming the sub-class 319.2 with numbers running from 319.201 upwards.

The new locomotive continued the GM-EMD tradition using the same engine and bogies but with other components completely new such as the generator.

Two units also received a brown, yellow and orange livery named Estrella.

The class 319.3 initially worked on passenger services, as designed, but have been displaced due to their relatively low power.

One unit fitted with Siemens equipment was used for testing on the installation of ETCS on the Madrid to Barcelona to France high speed line.
