Chuggington Wiki

— Zack's catchphrase

Zack is the head leader of the Chuggineers. He was first introduced in the Season 4 episode, Rescue at Rocky Ridge.


Zack joins Chuggington to head up the Chuggineers. This foreman is organised, hard-working and extremely safety conscious, making him the perfect leader of the Chuggineer crew and mentor to Brewster. Joined by his fellow team members Tyne and Fletch, this engineering team are responsible for all the heavy lifting, loading and building of bridges, tunnels, stations as well as laying track and making repairs.

Technical Details


Zack is loosely based on the General Electric (GE) Dash 8 series, Evolution Series, Dash 9 series and AC series, more specifically the C44-9W and AC4400CW due to their "wide cab" designs. However, Zack lacks the steps and handrails on the front, making him look more reminiscent to an Electro-Motive Division (EMD) F40PH, which is also evident by his underbody and backplate design, and the nose design of the cab also seems to bear a minor resemblance to an Electro-Motive Division (EMD) DDA40X.


Zack is painted blue with white stripes, red base, and an orange caution stripe between two big white caution stripes. He also has caution stripes on his front plough, backplate, and the left and right sides of his fuel tank and on top of where the headlights are above the engine.
