The Stadler WINK (Wandelbarer Innovativer Nahverkehrs-Kurzzug [English translation: convertible, innovative short train for local transport]) is a multiple unit railcar designed and built by Stadler Rail of Switzerland that is planned to enter service in 2020.
The WINK is a derivative design of Stadler's FLIRT railcars that is intended for service on lightly traveled lines. It has an aluminium carbody that can be customized in length by the customer, and can be powered by either diesel or electric powertrains with supplemental on board batteries. Arriva units will be delivered with Deutz diesel engines, running on vegetable oil fuel, and batteries charged by regenerative braking; the engines are planned to be replaced by additional batteries once electrification is installed over part of their route. Each trainset can carry about 275 passengers, with seating for 150, and has a top speed of up to 160 kilometres per hour (99 mph) depending on customer specification.
