Electric locomotive EP1 is a Russian electric locomotive which has been produced by Novocherkassk Electric Locomotive Plant since 1998. It is the first Russian passenger electric locomotive with the 2_o-2_o-2_o or Bo-Bo-Bo axle arrangement. There are, as December 2016, 866^[1][2] of these locomotives.^[3]

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.

This locomotive is an EP1 with a new driver's cab, as featured in the 2ES4K locomotive. This cab features a new modern control console, and climate control. This variant first appeared in 2007.^[3]

This locomotive is a further modification to the EP1M, featuring a more powerful motor, and also appeared in 2007.^[3]
