History

edit

In the 1990s there were few passenger electric locomotives in Russia. The existing Chesh electric locomotives CHS4 and CHS4t were rather old to head passenger trains. A decision was therefore taken to commission a new electric passenger locomotive.[4]

The first example of this locomotive was made in 1998, based on the existing VL65 design and modified for passenger traffic. The locomotive proved successful and was ordered in large numbers.
