Pesa Acatus

Pesa Acatus (Latin for boat) is a standard-gauge electric multiple unit produced in a single copy at the Pesa plant in Bydgoszcz in 2006, specifically for the Marshal's Office of the Łódź Voivodeship. During test runs, it was a four-car unit (ED74 series, 16WE unit type, 310Ba+411Ba+411Bb+310Bb car type), and it is nowadays operated in a three-car configuration (ED59 series, 15WE type). The design of the vehicle began in 2004, and a year later, it was offered in a tender and subsequently ordered. In April 2006, the production of the train was completed, and throughout that month, it underwent testing for approval for operation. On 29 May 2006, an official presentation of the unit took place in Łódź, combined with an inaugural ride. In 2011, the unit was withdrawn and awaited overhaul, which was ultimately carried out from December 2013 to June 2014. In 2016, the technically functional vehicle was withdrawn due to the expiration of its approval for operation. In 2007, a development version of the vehicle named Bydgostia was created. In 2010, the manufacturer also built the Acatus II model, and in 2014, the Acatus Plus family, but they are only related to Acatus by name.
