Despite his dilemma, Duncan wouldn't quit teasing Peter Sam about the incident at Cattle Creek, and spent the entire night cracking jokes.
Rusty, having enough the next morning, decided that he would tell Duncan the story behind the Old Iron Bridge.
Duncan rolled his eyes at Rusty upon the completion of the story.
"That is nothing but a stupid urban legend. Everyone knows there's no such things as ghosts! Perhaps that new fuels they gave you has made you insane."
Rusty shot a cold look towards Duncan. Before he could get another word in towards Duncan, the Scottish engine had vanished, running off to go and do work.
Rusty's crew had finished their morning coffee, and happened to glance over at Rusty. They could see that the little diesel was greatly upset, and considering that it was Duncan, decided that the Scottish engine deserved a lesson for his actions and harassment.
They decided to talk it over with Peter Sam's crew during the clean-up. Working together during their lunch break, the four men came up with a scheme to get back at Duncan.
"We'll do it tonight, that'll teach him to mess with our engines!"
"Better yet, why not get Duncan's crew in on this too?"
"Are you sure that's a good idea?"
"Believe me, ANYBODY that works with that factory engine knows that he's ALWAYS causing trouble to others, no doubt about that!"
"Very well, then."
The plan was formulated, and upon finding Duncan's crew, the plan was decided to be put into action later that evening.
Autumn was coming to an end on Sodor, and Winter was beginning to take its course. In areas such as Cattle Creek, fog would become a normal sight to see, often rising up from murky swamps below. Often, this was considered a ghastly sight by locals within the villages nearby.
The plan made by each engine's crew worked almost perfectly, as the fog was quite thick, and save for lights diffusing the fog, barely anything could be seen.
It had been a month since the bridge had been finished, repaired back to its original state, and with stronger iron bars in order to prevent further accidents from happening. The work had moved onto the quarry where old machinery were being taken down to leave space for the Ministry of Defense to place in their equipment.
Duncan was assigned to pull away the equipment, but was delayed until later that evening as the machines needed were malfunctioning, and needed repair. It wasn't until sunset that the old machines were taken apart and separated on flatbeds, in order to be ready for the Standard Gauge engines on the North Western Railway to take away to Mainland Scrapyards.
Of course, being Duncan, he wasn't too happy about this.
"Come on, come on! If we don't hurry up, Millie's going to take my favorite place in the shed, again! I'm not willing to deal with Sir Handel's snoring again!"
Duncan's crew rolled their eyes, while also hiding a sly smirk on their faces.
"You know the rules! The Thin Controller and Mr. Hugh wish for these to be disposed of properly for the scrapyards."
Duncan sighed, knowing he was defeated. He groaned even more.
Finally, the workmen finished loading up the scrap, and hopped aboard the coaches Rusty was waiting with. The little diesel left first, and after he departed the sun had set, leaving darkness with the only light being those of Duncan's lights, and the Full Moon above.
When secured, Duncan and his crew set off, blowing his whistle to let everyone around know they were leaving. Not too far away from the quarry, the fog began to roll, thick as always. Duncan didn't care, for he was too concerned about returning to the shed at Crovan's Gate in order to secure his spot.
A sudden stop happened within the middle of the Old Iron Bridge. Duncan grew awfully quiet. Although he claimed that Rusty's story about the bridge was a load of cow manure, he himself was secretly scared.
His fears didn't stop when he heard the sound of something being thrown into the swamp below.
His face grew pale. "It's the ghost! Take me back, take me back please!"
Duncan's crew secretly snickered, they knew they had ended Duncan's harassment once and for all, or so they thought.
The fireman was the first to look up. His eyes widened significantly in fear, he then tapped the driver's shoulders. The driver's eyes widened as well, and both men ended up holding each other in fright from the cab.
Within the fog appeared the shape of a rusty old engine, complete with two crew members inside. The engine began whistling fit to burst as loudly as she could. Both her and her crews eyes flashed red, and both began charging at Duncan and his crew.
Duncan and his crew screamed bloody murder, and all three shut their eyes, crying in fear of meeting their maker on the Old Iron Bridge.
A few seconds later, the men opened their eyes. There was no one there, and the fog had mysteriously vanished, leaving a clear night of just a pale full moon in the night sky.
Ducan's driver started him up again, and the three remained as silent as church mice from then on.
The other engines never heard what had happened in Cattle Creek that night, but all that they knew was that Duncan was silent for two straight months, not saying a word to anybody. The only hints they ever got were if Duncan would begin screaming bloody murder in his sleep every so often.
The Thin Controller is often sitting in his office wondering what happened to Duncan. After all, to the Thin Controller, a silent and hardworking Duncan usually leaves him to believe that something had crawled into his smokebox.
"I wonder if he's seen a ghost?" he said.
