Newag has been commissioned by LOTOS Kolej to modernise its SM42 locomotives to upgrade them to 6Dg type. It is the first overhaul of diesel locomotives that will be performed by the Nowy Sacz company for this Carrier. So far, LOTOS has operated 6Dg locomotives on a lease basis.
On April 9, 2014, LOTOS Kolej and NEWAG S.A. signed a contract for modernising three Sm42 Diesel locomotives. The contract provides an option to increase the object of the contract up to eleven locomotives in total. The Carrier will have made the decision on possible modernisation of more locomotives by March 31 each year.
The first three modernised 6Dg locomotives will be returned to the ordering party in July 2014 and another locomotives will be delivered subsequently, depending on orders placed, but no later than by the end of 2018.
The choice of the offer depended on the price (55%), experience (15%), cost of maintenance inspections (15%), individual fuel consumption (10%) and the guarantee (5%). Following individual negotiations, Newag’s offer was selected.
