The Stadler WINK (Wandelbarer Innovativer Nahverkehrs-Kurzzug [English translation: convertible, innovative short train for local transport]) is a hybrid multiple unit railcar designed and built by Stadler Rail of Switzerland that entered service in the Netherlands in 2021.

The WINK was unveiled in November 2017 when European operator Arriva announced an order for 18 trainsets, which it planned to place in service in the northern Netherlands beginning in 2020.

The WINK is a derivative design of Stadler's FLIRT railcars that is intended for service on lightly travelled lines.

[1] Arriva units were 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.

[1][2] 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.
