Thomas & Friends: All Engines Go!

While preparing for the Sodor Festival of Lights, Thomas accidentally damages the light he was meant to deliver. The mishap leaves him faced with a choice, and he decides to tell the truth about what happened. By being forthright, Thomas discovers that honesty not only resolves the problem but also earns him the respect needed to become the leading engine. He realises that trying to hide the error would only cause more trouble, and his willingness to own up demonstrates true leadership. The episode shows how his candid admission turns a simple mistake into a valuable lesson, reinforcing the idea that straightforwardness is the surest path to achieving the top spot among his peers.

The episode follows the troublesome Tess as she puts intense pressure on her coworker Nia. Under that strain, Nia makes a mistake that triggers an accident, causing sand to be driven into the gears of Tess's equipment during a crucial delivery. The sand clogs the moving parts, putting the whole operation at risk as the deadline draws near. Determined to fix the problem, Nia's turning to Sandy's newly developed super‑grease – a specialised lubricant meant to free stuck components. She applies the grease, hoping it will penetrate the grit, restore the gears to smooth function, and allow the delivery to proceed without further mishap.
