“Help! I'm goin' tae fall!”

Trusty Rusty is the twenty-fifth episode of the seventh series.


When Rusty crosses a wooden bridge, he hits a bump, and his driver inspects the bridge, realising that it is in early stages of collapsing. Realising that it may soon be dangerous to cross, Rusty immediately hurries off to warn the engines. Arriving at the depot, where all the engines are getting their coal, he warns them about the bridge, but Duncan is skeptical, asking how Rusty would know, saying that he is only a diesel. He puffs away without waiting to be filled with coal. Rusty tells the Fat Controller about the bridge, and he agrees to send engineers to inspect it. After Rusty's driver puts up a sign reading "Line Closed," the engines have to travel a different route.

Meanwhile, Duncan is planning on getting more coal for the journey home, but the coal staithe is empty, so he asks Skarloey where he can find the nearest staithe. Skarloey tells him it is on the other side of the wooden bridge, warning Duncan not to cross it under Rusty's orders, but Duncan ignores his warnings, and he and his driver decide to face the risks. When Duncan arrives at the junction, his driver removes the warning sign, and they puff towards the bridge. Not knowing it is a mistake, Duncan runs out of steam, causing him to stop on the bridge, which then suddenly starts to crumble from Duncan's weight. Hearing the news from Skarloey, Rusty races off to rescue Duncan. He pulls him off the bridge, just before it finally collapses.

That evening, the Fat Controller scolds Duncan for his actions. Duncan thanks Rusty for saving him and being brave, and the Fat Controller praises him as a Really Useful Engine.




  • Going by production order, this is the twenty-second episode of the seventh series.
  • Stock footage from Stepney Gets Lost is used, which also was a deleted scene from Rusty to the Rescue.
  • In the US version, Rusty saying, "Don't use the old wooden bridge - it's dangerous!" when he warns the other engines not to cross is repeated after he rescues Duncan. This does not happen in the UK narration.
  • The scene of Rusty rescuing Duncan from the bridge is similar to Toby's Tightrope, as Mavis and Rusty are both diesel engines and Toby and Duncan are both steam engines.  
  • This episode marks the last of a few things:


  • When Duncan arrives at the coal staithe, Skarloey already looks shocked even before the former headed for the bridge.
  • When Rusty races to the rescue, the scene is mirrored because viewers can see that his number and name are reversed and the door to his cab is on his left when it should be on his right.
  • When Rusty pulls Duncan clear of the bridge, it suddenly jerks downwards slightly as it begins to fall; this is due to a film cut.
  • Wires can be seen under Duncan when the narrator says, "A beam snapped." The wires are also seen when he is about to fall, and when Rusty pulls him clear.
  • The narrator says, "Rusty chuffed bravely onto the bridge," but Rusty is a diesel.
  • When Rusty moves closer to Duncan on the bridge, studio equipment is seen sliding out behind the cliffs behind Rusty on the right hand side of the screen and again when the narrator says "soon they were coupled up."
  • When Duncan runs out of steam on the bridge, the narrator says he used up all his coal, but the coal can still be seen in his bunkers.
  • Because stock footage is used, Rusty is in his small scale model in the first cut.


  • Rusty:  Don't use the old wooden bridge. It's dangerous.
  • Duncan: How would you know? You're only a diesel. 


  • The Fat Controller: [to Duncan, after crossing the collapsed bridge earlier] That was very irresponsible. 
  • Duncan: Yes, sir. Sorry, sir, and Rusty, you were very brave.
  • Rusty (US Verison Only): Aw, thanks.
  • The Fat Controller: Yes, Rusty. You really are a useful engine.
  • Rusty: Thank you, sir.
