EP20

The EP20 (ЭП20) is a type of 6 axle Bo'Bo'Bo' electric passenger locomotive being built for Russian Railways by Transmashholding's Novocherkassk Electric Locomotive Plant. The locomotive was designed by Tekhnologii Relsovogo Transporta (TRTrans), a joint venture between Transmashholding and Alstom.

An order for 200 locomotives was placed in 2010, and the first production unit formally presented in 2012.

Design

The EP20 was developed by an Alstom-TMH joint venture "TRTrans", established in Novocherkassk, by French, Belgian, and Russia based engineers.

One specification for the design was the ability to haul 24 coaches at 160 km/h or 17 vehicles at 200 km/h on straight level track.

The EP20 has a modular design. The locomotive body consisted of an underframe and sidewalls, with removable roof segments, and separately manufactured cab units. The driving cab modules were sourced from PKPP MDC (Ukraine); the cab design included a progressive deformation steel cage for impact absorption, and incorporated heating and air-conditioning. Access was via side doors in the main bodyshell, accessed via cab unit rear doors. PKPP MDC also supplied washrooms (2 per unit), incorporating a retention toilet system supplied by EVAC.
