Pesa submitted a bid of Zlotys 166.2m ($US 51.2m) for the contract, while the only other shortlisted bidder, Solaris, offered a price of Zlotys 169.2m.

Pesa will supply its Swing LRV which is already in service in Warsaw, Gdansk, and Szczecin. Deliveries are due to start in October 2015, although the order is subject to the conclusion of a funding agreement with Poland's Ministry of Infrastructure and Development.

MPK Lodz currently operates a fleet of 456 trams, the most modern being a batch of 10 type 122n LRVs supplied by Pesa in 2007.
