Time is Time


Not only the Engines on Thomas' Branch Line are having difficulties, but on Edward and Duck's Branch Line too. Edward, Duck, Donald, Douglas, Bill, and Ben are preducing Thick Black Smoke. Every now and then, BoCo is often coming to pull the Engines back to the Sheds. One day, Douglas takes some ballast wagons to be filled up, but the Trucks want to play a trick, so they hold back, making Douglas so cross, he preduces the Thickest Black Smoke. Everyone and everything gets lost in a Thick Black cloud. Rex's green paint is covered in dust. The Trucks coughing too, do no more tricks. Later he tells the Engines about, and they all agree Something Has to be done.
