Northern placed a £492m order in January 2016 for 25 two-car and 30 three-car class 195 sets, together with 31 three-car and 12 four-car EMUs (class 331). Financing for the order is being provided by Eversholt Rail.
The 160km/h class 195 is equipped with MTU power packs incorporating 390kW Daimler engines and hydraulic-mechanical transmissions supplied by ZF.
Northern plans to introduce the first Class 195s on Chester - Leeds services in December.
