- “Well Oliver, so you don't know your own strength, is that it?"
- ―The Fat Controller and Oliver
Toad Stands By is the twentieth (twenty-third in Australia) episode of the fourth season. It first aired in the US on the Shining Time Station special One of the Family in 1995 and re-aired in the Mr. Conductor's Thomas Tales episode, Wildlife in 1996.
Oliver returns from the works after an earlier incident with the trucks that accidentally pushed him into the turntable well. Oliver seems as good as new but is worried about the trucks, thinking that he would rather not use them. The trucks, prompted by their ringleader, S.C. Ruffey, sing a rude song to spite him. Thomas, Percy and Duck are shocked and angrily order them to be quiet, but since they can't be everywhere at once, the trucks just continue singing where they aren't.
Toad, fearing that the matter may escalate, asks Douglas to speak with Oliver and gives him an idea. Oliver, feeling a sense of responsibility after what the trucks did to him previously, agrees with Toad. Following Toad's advice, Oliver handles the worst trucks two by two so he can handle S.C. Ruffey last. Oliver soon shunts S.C. Ruffey and his lieutenants and prepares to pull them, but S.C. Ruffey whispers to the trucks to hold back and they do. Oliver, however, is determined and simply pulls S.C. Ruffey apart, much to the horror of the other trucks and the delight of Duck and Toad.
The Fat Controller arrives and scrutinizes the remains, he attributes it to S.C. Ruffey's poor build due to material fatigue and design flaw and decides to have him repaired. Sometime later, the trucks become fearful of Oliver and whisper to each other not to anger him. S.C. Ruffey, who is now repaired, wisely remains silent.

- This is the fourth time where Douglas appears without Donald, the first being in Escape, the second being in Rusty to the Rescue and the third being in Thomas and Stepney.
- At the beginning of the episode, the scrapyard Oliver passes is really the Skarloey Railway Engine Sheds set redressed with scrap models of Thomas, Gordon, and Donald and Douglas.
- Oliver no longer has a Brooklyn accent in the American narration.
- There are some differences in the US and UK narrations. Some differences are:
- When Duck yells to Oliver and the trucks, "Go it." In the UK narration." in the UK version, but in the US narration, he just says "Go on.".
- In the US narration, the line "OOOOOOOOOHHHHH! " is omitted.
- In the UK narration, Douglas says, "Of course, Toad." In the US narration, he says "Certainly, Toad!"
- This is the only time tankers have faces until The Fastest Red Engine on Sodor. The faces are the same ones used on the Skarloey Railway's slate trucks.
- The song sang from the trucks when Oliver arrives at the yard has the same tune of Pop Goes the Diesel.
- The loud crashing sound effect heard when S.C. Ruffey falls apart has also been used in several other Classic Series episodes, notably in the fifth season episode, Rusty and the Boulder, when Boulder damages the sheds at the yards, and in a few New Series episodes up until the twelfth season episode, Mountain Marvel.

- Toad asks Douglas if he can work with Oliver, even though Oliver did not give Toad to Douglas after his escape in the TV series like he did in the Railway Series. This error is due to the fact that much of the episode's script is copied word-for-word from the original story.
- When the trucks are singing, a spider can be seen crawling a van before the close-up of Duck.
