Chuggington Noir is the twenty fifth episode of Season 6.
Brewster is helping out at the Docks; simultaneously, Hodge and Eddie are fixing the carousel. Cormac arrives to pick up a new electric motor for his crane- ten times more powerful than his old one. After clearing the Docks to make way for an incoming ship, Brewster sees a thick fog approaching. Skipper Stu assures Brewster that the ship will be fine with the lighthouse, when suddenly, it goes out.
Eddie inspects the lighthouse, but finds out that nothing is broken- the power has gone out. Brewster puts on his classical detective persona. Hodge volunteers to assist him, and the two set off.
When the two chuggers arrive at the Depot, Brewster gets distracted by a squirrel while Hodge notices that the lights are on in the Repair Shed. Hodge remembers that he was the only who left everything inside on, and turns it all off. He then understands why Eddie always tells him to turn the lights off when he's done working.
Despite turning the Repair Shed off, Vee tells Brewster and Hodge that the lighthouse still isn't turning on. After reflecting on the situation again, Brewster tells Hodge that he's talking to the night, which causes Hodge to hear something coming from Roundhouse Park. It turned out that Hoot and Toot had started watching a film, but got distracted and left it on. Even after turning the movie off, the lighthouse still will not turn on- to make matters worse, the ship appears to be coming in early.
In a last-ditch effort, Brewster and Hodge turn everything on in Chuggington- but the lighthouse still stays off. Brewster begins to doubt his detective talent when Hodge notices a light coming from the Drop and Load Yard. It turned out that it was Cormac's new motor that was stealing all of the energy- after shouting at him multiple times, Brewster and Hodge are able to get Cormac to turn the crane off- just in time, too, as the ship makes a sharp turn just in time to avoid the rocks.
Brewster reflects on the night's events, and he and Hodge head on home.
