In 2009 Electric Locomotives Repair Works (Zakłady Naprawcze Lokomotyw ElektrycznychZNLE) of Gliwice completed the prototype of the first brand-new Polish electric locomotive in almost twenty years. Designated E6ACT and known under commercial name ‘Dragon’, it was ordered by several operators, nine examples being completed until late 2014. Further orders are at hand. Six-axle ‘Dragon’, with its maximum speed of 120 km/h, is intended mainly for heavy freight traffic and offers a modern replacement for obsolescent classes ET41 and ET42. In 2010 ZNLE Gliwice began first studies concerning a four-axle locomotive of similar rating, to be built in both universal (drafts up to 3 200 tonnes, 160 km/h) and passenger (200 km/h) variants. It was intended to build DC (3 kV), AC (15 kV 16 2/3 Hz and 25 kV 50 Hz) and multi-system versions, so that entire family would include six types: single-system DC E4DCU/DCP (universal/passenger),  dual-system AC E4ACU/ACP and multi-system E4MSU/MSP. Commercial name ‘Elephant’ was changed to ‘Griffin’ in 2011. Later a diesel-powered variant, designated D4MSU, was also proposed.

Until now (February 2016) only a single E4MSU was completed and shown for the first time at the InnoTrans Fair in Berlin in September 2012. It was the first multi-system electric locomotive built in Poland. In 2013 it underwent extensive tests at experimental railway establishments in Żmigród and Velim (Czech Republic). It was also briefly tested by PKP. It was planned to complete the first E4MSP in 2013, but this did not see fruition. Prototype E4MSU-001 was also tested by several private operators (Ecco Rail, Pol-Miedź Trans, CTL Logistics and Kolprem). Second presentation took place at the TRAKO 2013 Fair in Gdańsk in September 2013: the locomotive was sporting Newag livery, as in the meantime ZNLE Gliwice became Newag subsidiary. In January 2016 Lotos Kolej announced that they would lease five locomotives of this type, to be delivered until June 2017.

In May 2014 an agreement was signed between Newag and Ɖuro Ɖaković Specijalna Vozila of Slavonski Brod, Croatia, concerning co-operation in design, production and marketing of electric locomotives. On its basis ‘Griffin’, in the multi-system version, is to be built in Croatia. Until today (January 2016) production has not yet started.
