Whiff

Whiff is a dark green 2-2-4 rubbish-collecting tank engine with dark green wheels and glasses, the first engine character in the TV series to do so.

In Emily's Rubbish, Emily has to work with Whiff. She is quickly teased for spending time with a smelly engine. But Whiff is the only engine who doesn't mind moving trucks full of rubbish. He shows up and takes the rubbish trucks away for Emily when she can't move them by herself from the path of Spencer, and after this Emily is no longer afraid to call Whiff her friend. Whiff seems to have a two-tone whistle, and is the second steam engine in the TV Series to have no side-rods (The first being Fergus).

Whiff is based on the NER 66 Aerolite, found at the National Railway Museum.
