One of the novelties displayed at the 2012 InnoTrans fair in Berlin was the prototype 111Ed electric locomotive from Bydgoszcz-based Pesa company. It was intended as the first member of an entire family of model universal locomotives, commercially named ‘Gama’, which was also to include a diesel-powered one. The latter materialized in July 2014 as factory type 111Db and was displayed at the next InnoTrans fair in September. At that time Pesa already had a firm order for ten production examples, placed by PKP InterCity. They were intended to supplement (and possibly later supersede) elderly SU46s; pending their appearance, PKP IC leased five class 754 diesels from Czech railways. First 111Db for this operator began tests in May 2015, commencing line service in June. Last, tenth example was delivered in November. These locomotives have been assigned a ‘hybrid’ service designation SU140, promptly changed to SU160, wherein ‘SU’ indicates universal diesel locomotive and ‘160’ is maximum speed (in fact maximum operational speed has been set at 140 km/h, but homologation procedures require an ability to run at speed higher by ten percent). Teething troubles have been reported as minor and concerning auxiliary electric equipment and ABS system. Prototype, designated 111Db-001, initially remained the manufacturer’s property and was used for various tests. In June 2015 it was sold to Pol-Miedź Trans and later, in May 2016, to Orlen KolTrans.

In December 2014 prototype was tested by PKP Cargo, although these tests were contracted by PESA in order to confirm suitability for freight traffic. Rumors on possible order were promptly denied by this operator.
