Type 111Ed, designed and built by Bydgoszcz-based Pesa company, is an entirely new four-axle single-system universal electric locomotive, the first one in Poland fitted with an auxiliary generator driven by a diesel engine. It was developed at the manufacturer’s risk and intended for both PKP and private operators as an replacement for old and obsolescent locomotives, of which many are still in use.

Type 111Ed was the first locomotive of the entire family, with commercial name ‘Gama’, to include both single-system (3 kV DC) and multi-system vehicles, the latter with maximum speed of 160 and 190 km/h, as well as a diesel-electric one, initially intended to be powered by an unspecified engine rated at about 2200 kW. The latter materialized in 2014 as type 111Db, with 2400 kW MTU power unit.

Prototype 111Ed, officially named ‘Marathon’ due to declared range with power supplied by the auxiliary generator, was shown at the InnoTrans international fair in Berlin in September 2012. Later it underwent tests in Bydgoszcz, Poznań and Żmigród. During these tests new locomotive attained 173 km/h and, except from few remarks concerning control panel layout, was found entirely satisfactory. In January the locomotive began service trials with Lotos Kolej. On March 1 tests with PKP InterCity were commenced, 111Ed hauling passenger and express trains between Warsaw and Kraków, later also Poznań, Gdynia and Wrocław. After minor modification at the Pesa works it returned to Lotos Kolej for further tests.

Current Pesa offer includes as many as nine distinct versions, namely:

-        111Ea – 3 kV DC, freight;

-        111Eb – 3 kV DC, universal;

-        111Ec – 3 kV DC with auxiliary diesel, freight;

-        111Ed – 3 kV DC with auxiliary diesel, universal;

-        111Ee – 3 kV DC, 15 kV and 25 kV AC, freight;

-        111Ef – 3 kV DC, 15 kV and 25 kV AC, universal;

-        111Eg – 3kV DC, 6000 kW, passenger;

-        111Eh – 3 kV DC, 15 and 25 kV AC, 6000 kW, passenger;

-        111MS – 1.5 kV and 3 kV DC, 15 kV and 25 kV AC, 6400 kW, passenger.

Until now, only two of them have reached the production stage. First firm order was placed in April 2014 by Koleje Mazowieckie, for two locomotives in the 111Eb variant. They were delivered in December and are operated solely in passenger traffic, with new push-pull type drafts also ordered from Pesa. 111Eb-001 was displayed at the TRAKO 2015 fair in Gdańsk in September 2015. Two more 111Ebs were purchased in 2016 by PHU Lokomotiv and sold to Industrial Division in September 2017. In April 2015 prototype 111Ed-001 was purchased by Ecco Rail private operator, to be sold to PHU Lokomotiv a few months later. This locomotive was later also sold to Industrial Division. Currently (April 2022) the latter company still owns three 111Es, which have been leased to several private operators.

Apart from above-mentioned prototype, 37 111Eds have been built. Of these, 111Ed-030, delivered in July 2021, was purchased by Pol-Miedź Trans and still remains in use with this operator. The remaining 36 examples were ordered by Rail Capital Partners, a Bydgoszcz-based leasing company co-owned by PESA. They have seen service with several Polish private operators, including Alza Cargo, Bahnoperator Polska, Captrain Polska, JSW Logistics, KOLTAR, Lotos Kolej, LTG Cargo Polska, Olavion, Orlen Kol-Trans, Pol-Miedź Trans, PPM-T (a track maintenance company) and PUK Kolprem. At least one example saw a brief service with PKP Cargo. In July 2021 three 111Eds were ordered by PCC Intermodal. Further orders may follow. During InnoTrans 2016 international fair in Berlin letters of intention were signed by Pesa and two Czech operators, EP Cargo and LocoTrain, which intended to place their orders. Until now, however, these orders have failed to materialize.

Main line electric locomotive with auxiliary generator is a comparatively new concept. Locomotives with such arrangement have been offered by Siemens (Vectron AC Last Mile) and Bombardier (TRAXX F140 AC – German class 187). It has to be noted, however, that due to low speed and short range (about 40 km) type 111Ed will probably be of little use with passenger trains in conditions other than exceptional. Type 111E is the second new electric locomotive of indigenous design, built in Poland since completion of the last EP09 at Pafawag in 1997, and the first one from Pesa. Currently Pesa, formerly a railway stock repair establishment (founded in 1851), is the largest manufacturer of rail vehicles in Poland, which has so far supplied over 100 EMUs for various operators and has large orders from Russia and Germany.
