A/N: So, if you're wondering what the title is about, read on! It'll be interesting, I promise. Anyway, I would very much appreciate reviews, especially if those reviews have some story ideas in them. You don't even need a full idea, maybe even just a character or two. I'll think of something.
Percy had been helping out at Vicarstown after Rosie had ended accidentally shunted a very full truck through an old shed wall, and promptly got shut up in the shed for it. His job was the same as usual: station piloting, and, if necessary, short runs down the Norramby branch. Now, the station at Vicarstown is elevated, and thus, doesn't have much room to spare for moving coaches about. This fact annoyed Percy a lot, since he was used to the sidings next to Knapford station, which he always used when he was piloting there. He was in a rather disagreeable mood that afternoon, and decided that the best way to let off some steam would be to do actually do it, preferably in someone's face. But who do I wheesh? He pondered, but he was snapped out of his thoughts by a long, deep, and very loud whistle. "Perfect! Gordon's here!" And so he made his plan to vent his frustration.
Gordon had made it to Vicarstown in just under record time, and was feeling very pleased with himself. "Now, to get some rest, and get turned around for the trip home." He was uncoupled from his coaches almost immediately, and set off towards the Vicarstown yard, which the sheds were very close to, in order to do just that.
An important fact about Vicarstown yard, as well as the nearby sheds, was that they were actually at ground level, as opposed to raised 3 stories in the air. They were also just to the east, and slightly south of, the main line. This meant that engines heading to the yard, or the sheds, had to be switched onto a somewhat steep incline, which ended in a rather sharp curve underneath the main viaduct. Smaller engines made the trip just fine, but for an engine of Gordon's size, he had to be very careful to not head at it too fast, or else he would very easily tip over, which would be very bad for a number of reasons.
Unfortunately for Gordon, as he was making his way to the track leading to the sheds, Percy crept up behind the big, blue express engine as quietly as he could, and, once he was satisfied, he let the steam build in his pistons, and after a faint hissing began emanating from his cylinders, he waited a few more seconds, before blasting open his cylinder doors with a mighty "WHEESH!" The short, shrill shrieking from Percy's now-closed cylinders was accompanied by a massive blast in pressure, and two sizable jets of steam. This assault on Gordon's senses proved too much, and the express engine raced off as fast as he could to get away from Percy. However, all this had happened before Gordon had actually passed the slope, and so he was left with his wheels locked and his brakes screeching furiously, sparking as they went, before finally, Gordon came off the track, burst through the wall, and onto the streets below. Percy, who had been up until that point fuming, had realized only just before Gordon had gone off the rails that something was going to, and indeed, had, gone wrong. Luckily, his wheeshing and gotten the attention of all of the staff, and the breakdown train was brought in. Unfortunately, they had a problem: Given where exactly Gordon had derailed, they couldn't exactly pull him up from the incline, and he was too far from the main line to be reached from there. However, Diesel Ten happened to be passing through with a scrap train, and using the hydraulics in Pinchy, carefully guided Gordon over to a place where he could be lifted back up. This did mean Gordon's wheels were severely damaged, and thus, he would have to spend a massive amount of time in the works before he was back in working order.
Percy had made the wise decision to make himself scarce before the rescue team started their investigation. He decided that the best course of action was to head down the Norramby for a little bit, and wait for it to blow over. And it worked, for a little while. Eventually, however, he was found out, as Gordon was in good enough shape where he could manage to hold a proper conversation. Sir Topham Hatt was now furious at Percy, not just for causing the accident, but not owning up to it, either. And so he ordered Percy be locked in the Vicarstown sheds for the next week, unless absolutely necessary.
A/N: And here we go! What crazy things will come of Percy's wheeshing? I'll take suggestions, so review with some!
