RENFE - Spain
Some high-speed variable gauge trainsets class 130 have had two coaches replaced by diesel generator cars such they can operate over non-electrified tracks. They are known as class 730 and operate e.g. from Madrid to Galicia. Such a trainset is seen at Madrid Chamartin, with a diesel generator car in the center of the picture.
