When the light faded, Thomas and his crew didn't know where we were.

"Twilight? Where are we?" asked Thomas.

"Muffle Mountain, Thomas," I replied.

"I think I feel a… a little dizzy," groaned Thomas.

"I'll be back," I said, "Spike, you stay here with Thomas and his crew."

"Eh, okay… I guess…"

"Coal, Twilight," Thomas called to me, "coal from the North Western Railway – please remember. I think it's important."

"I will." And with that, I ran down the mountain.

"It's getting windy up here…" moaned Thomas.

Coincidentally, Chrysalis was at Muffle Mountain too, setting up the dynamite. She didn't know that Spike, Thomas, and his crew were already there. Once she was ready, she took up the plunger and set it off!

BOOOOOM!

"Oh!" groaned Thomas, "What was that?!"

Suddenly, the cliff they were on gave away, and Thomas began to roll down the mountainside!

"Bust my boiler!" he cried. Spike, the driver and fireman hung on for dear life!

"Jane, stop this crazy thing!" cried Spike.

At the bottom of the mountain, I saw Flash come in on his horse.

"Where's Shining Armor?" I gasped, "Can you take me to him?"

"Jump up!"

"I knew I could count on you, Flash," I smiled.

Meanwhile, Thomas was still going down the mountain out of control. He sped down right past a bewildered Chrysalis. Recovering from the surprise, she gave chase.

"You're not real," scowled Chrysalis, "you're a toy, a big blue toy! I could control you any way I like!"

Thomas' fireman spotted Chrysalis.

"Stay away from our engine, you harpy!" he shouted, and began swinging his shovel at her.

"How dare you attempt to hit a lady!" she snarled.

Suddenly as Thomas got onto straight land, a whoosh was heard, and he started going under the ground! Chrysalis was caught in his wake and was flown off her motorcycle into the light as well.

Spike, Thomas, his crew, and Chrysalis found themselves on another branch of the magic railway.

"Is that crazy woman behind us?" asked the driver.

The fireman looked back and saw Chrysalis floating along the magic railway.

"We better get rid of her!" exclaimed Thomas. His crew and Spike agreed, and soon the little blue tank engine puffed fast as he could. The three people aboard his cab were clinging on for dear life, because the track was bumpy, but they were hoping to get Chrysalis off their tail.

Chrysalis was bumped around like a shirt tumbling in a dryer. She didn't like this at all.

"Stop!" she cried as she was bounced around, "I command you to stop!"

"Sorry, crazy woman," called Thomas, "but I'm calling the shots here!"

Back in the workshop, Shining Armor was looking at some blueprints when…

"Shining Armor! Cadance!"

"Oh, Twilight!" he gasped, "I'm so glad to see you."

"I was at Crovan's Gate," I said, "and these narrow gauge engines say you might have been around Sodor before. But Miss Celestia is really ill, Luna's in danger, and I had to leave Spike and Thomas behind. Please help me…"

As I said those last three words, I turned to face the purple 0-4-0 tank engine in front of me.

"We'd like to help, Twilight," said Cadance softly, "but nothing seems to work."

I heard Cadance, but my focus was to the faceless tank engine. Then I could see the workshop led into where Spike and I came from in the magic railway.

"This is the lost engine from long ago, isn't it?" I asked, facing them once more, "Now we can go back and help Miss Celestia and Luna."

"I'm sorry, Twilight," said Shining Armor, "but we don't know how to because we can't make her steam."

As my brother's words sunk in, part of Miss Celestia's clue to her gold dust came to me…

Stoke up the Magic in the Mountain and the Lady will smile…

Then I realized that I knew the answer!

"Lady…" I said, reading the name on the engine's sidetank, "Is that her name?"

"Yes," said Shining Armor.

"Coal!" I said, "Special coal from the North Western Railway! That's what Lady needs."

I looked over at Flash, who was examining his horse's hooves. They were all covered in gold dust.

"Flash," I called to him, "while we were in the magic railway, we passed a coal truck. Do you think you can fetch it?"

"Of course I will." And with that, Flash rode off on his horse.

Back on the North Western Railway, Diesel 10 was still racing along with Luna on his roof. As they got closer to Barrow, Diesel 10 noticed Splatter and Dodge in a siding.

"Why haven't you two destroyed those buffers yet?!" the big diesel roared.

"We were gonna get to it," said Splatter.

"But that steamroller turned against us," finished Dodge.

"You two are working for the wrong side!" Luna called as Diesel 10 roared past.

"Does she mean that?" asked Dodge.

At last, Diesel 10 was approaching the smelter's shed at the scrapyards.

"I'm sorry, Twilight," Luna gasped to herself, "I'm sorry, sister, that I haven't been responsible, reliable, or really useful, but I will be!"

As Diesel 10 roared into the smelter's shed, there ahead of them was a very shocked James! He had been turned around and was preparing to back down onto his trucks on the opposite line. Diesel 10 screeched to a halt as Luna was catapulted into the air and landed on James' roof!

"James," gasped Luna, "thank goodness you're here!"

Frantically, Luna sat up and pulled out her conductor's whistle. She blew on it, but no gold dust came!

"Aha!" said Diesel 10, raising his claw, "So you've lost your sparkle too, huh?" He cackled maniacally. "End of the line, Twinkle Toes!"

"Oh no," gasped Luna, "it's empty!"

"Here we go!" said Discord, "Into the smelting pit!"

"Luna, what are we going to do?!" cried James. His crew was also in a panic, and they felt like sitting ducks.

"I'll think of something!" cried Luna.

They were getting closer and closer to the buffers.

"That's it now," said Diesel 10 in a devious manner.

Suddenly, Luna remembered the gold dust she had promised to hold on to for me.

"I'll find you some more, Twilight," she said to herself, "I promise, but if I'm going to be any help at all, it's now or never. I've got to use up the rest of this stuff!"

She dug into her pockets and poured the remaining gold dust into her whistle. At that point, James had just backed into the buffers. Since he was still moving, the buffers fell into the smelting pit.

"Are you ready?" asked Discord.

"No we're not!" snapped James.

"James the brains, get us out of here!" exclaimed Luna, and with one blow on the whistle, gold dust surrounded her and James and they disappeared!

"Now we are!" remarked James as he disappeared.

"What the-?!" cried Discord.

"I thought they'd run out-?!" Diesel 10 spluttered.

James and Luna rematerialized at Vicarstown.

"Huzzah!" cheered Luna, "Good has triumphed over the wicked!"

"Hoo-yah!" said James in excitement.

"That was close," said his driver.

"I thought we were goners," added the fireman.

Luna climbed off James' roof, into the red engine's cab, and then jumped off the footplate.

"Thank you for the lift, James," she said, "now I must find my sister."

Luna looked and noticed they were not alone. They had arrived on a siding near Vicarstown. There watching them were Percy, Edward, Gordon, Henry, Toby, Emily, Duck, Miss Celestia, Big Macintosh, the Cutie Mark Crusaders, and the other five girls.

"Sorry I took so long getting back, sister," Luna said to Miss Celestia, and explained everything.

"Luna, we're both out of gold dust, aren't we?" asked Miss Celestia.

Luna looked at her own whistle, and nodded sadly in agreement. "Bankrupt…"

Suddenly, Arry and Bert rumbled in.

"What are you two doing here?" asked Gordon crossly.

"We've come to cause trouble for you steamers," said Arry.

"You said that yesterday!" called Percy.

"Well, we never got around to it until now," said Bert, "now we're gonna smash them magic buffers."

The diesels rumbled off towards the magic buffers.

"You shall not get away with this!" shouted Luna.

Before anyone could say anything, Luna scrambled up to a hill close to the buffers and began to push a boulder. But it was too heavy. Thankfully for her, Arry and Bert had begun arguing over who should smash the buffers.

Just then George arrived, his driver having recovered from the punch and had taken control once again. George could see what was going on and wanted to help stop Arry and Bert.

James spotted George. "Well, go ahead and push the boulder," he called, "just don't smash the buffers!"

George trundled up to the top as fast as he could, which wasn't very fast at all.

"Can we be of assistance, miss?" his driver asked Luna.

"Yes, please," she gasped, "we must stop those diesels from smashing the buffers!"

George rolled up and pushed the boulder with all his might until the boulder rolled down the hill in the direction of Arry and Bert, away from the magic buffers.

"Look out below!" called George.

Arry and Bert were shocked at the sight of a large boulder charging towards them and oiled backwards fast as they could into another siding! Arry braked before hitting the buffers, but Bert rammed into him and the two diesels hit the buffers with a crash!

"Watch it, clumsy wheels!" snapped Arry.

Then the boulder rolled in front of them, blocking them from getting out. Arry and Bert were trapped like rats.

"This is your fault, idiot!" said Arry crossly.

"No, it was yours!" argued Bert.

"Huzzah!" cheered Luna, "The fun has been doubled!"

Everyone else cheered, but Fluttershy was concerned.

"I hope Twilight, Spike and Thomas are okay," she said with worry.

Meanwhile in the magic railway, Flash and his horse had finally found the coal truck. He fixed a rope between the horse and the truck, made sure it was tight, and he made his journey back.

"Woah!" the truck shouted, "Take it easy with your horse, will you?!"

"Sorry about that!" Flash called to the truck.

Back in the workshop, Shining Armor and Cadance were getting Lady ready for her journey. As I watched them, a question came to mind.

"Why didn't you tell anyone about Lady?" I asked.

"I felt I'd let everyone down," said Shining Armor, "most of all, Cadance's family; they chose me to be Lady's driver."

"Why did Chrysalis call you a liar?"

"She never believed anything we said was true," said Cadance.

"Did you ever get to take a ride on Lady?" I asked Cadance.

Shining Armor gave a sad sigh. "Chrysalis and Sombra crashed Lady before I had the chance to take Cadance on a ride," he said, "I wanted this to be our Shining Time."

I was puzzled. "Shining Time?"

"A wonderful journey," said Cadance, "when the wheels turn and the rails shine. It was always going to be tomorrow; tomorrow Lady would work, and tomorrow would be perfect…"

"But eventually," finished Shining Armor, "we gave up on tomorrow…"

"Please don't," I begged, putting my hand out to my brother, "don't give up on today too…"

Shining Armor remembered something and pulled out the friendship bracelet I had made for him and put it on his wrist. And in that moment, he gave a wonderful smile for the first time since his wedding.

Just then, we saw Flash and his horse pulling the missing coal truck.

"Twilight, Shining, and Cadance," he called, "I've got the coal."

Before long, Lady's bunker had been filled with the special coal. Shining Armor then began to shovel some into the firebox. Once Lady had steam up, smoke billowed out of her funnel, her headlamps flickered on, and Shining Armor blew the whistle. With me, Cadance and Flash aboard with him in the cab, Lady slowly began to move from her siding into the tunnel, leaving the empty coal truck behind.

"Hey! What about me?!"

Before long, Lady was puffing down the magic railway.

"Stoke up the Magic in the Mountain and the Lady will smile," I said to myself, "that's part of Miss Celestia's clue to her gold dust. But what else is there?"

"Twilight, look!"

Flash had me go to the back of Lady so I could see what he was talking about. The rails were beginning to turn gold as shavings flew from behind Lady.

"The railway's getting its energy back," Flash said in amazement.

Shavings of all the colors of the rainbow fell behind Lady as she puffed along the magic railway, and I caught some of them in my backpack. The yellow sky hiding behind the trees was turning green.

"Well, Lady," said Shining Armor, "the lights are all green now; green for glory."

"I'm so glad we finally got to have this journey," Cadance smiled.

"So am I," said Shining Armor, "and I'm glad Twilight's with us too."

I smiled and gave my brother and sister-in-law a hug. The twisted, thorny trees disappeared and in their place was a beautiful green meadow before a blue sky. And with a golden flash, Lady's face reappeared on her smokebox door.

"So Shining Armor, you didn't forget about magic," she said happily, "it's safe inside you."

Shining Armor and Cadance smiled hearing this. As Lady continued down the magic railway, we heard another whistle.

"Thomas!" I said excitedly.

"You've found her!" exclaimed the little blue tank engine, "And she's beautiful!"

"She looks amazing!" cried Spike from his cab, and waved to us. We waved back at him.

By that point, the branchline where Thomas was on met the magic railway's main line. He was still bumping along, but as Lady's wake of shimmering shavings settled on the rusty track, Thomas gained traction and sped up.

Within minutes, Lady charged through the magic buffers.

"We're back at Vicarstown," I said, "stop at the halt."

At the halt waiting for us was Miss Celestia, Luna, Big Macintosh, the Cutie Mark Crusaders, and the other five girls. The rest of the Steam Team and Duck were there as well.

As soon as we got out of Lady's cab, everyone came to greet us.

"Miss Celestia," I said, "this is my brother Shining Armor."

"Why would I not know my nephew-in-law?" Miss Celestia grinned.

I was surprised.

"You mean you're Cadance's aunt as well?" I asked.

"Indeed," replied Miss Celestia, "didn't Shining Armor mention that to you?"

"Ah, no I haven't," he admitted.

"He's been a little upset for a while," Cadance explained. We knew why, don't we?

"Luna," Miss Celestia said to her sister as she gestured to Lady, "do you realize who this is?"

"Is this the lost engine?" Luna said in surprise.

"Indeed I am," replied Lady.

"It is great to see you again," smiled Edward.

"It has been a long time, Edward," said Lady.

"You two know each other?" asked Fluttershy.

"Of course," said Edward, "I was the one who helped bring her to Muffle Mountain for hiding."

"Wait a minute," said James, "you knew where she was this whole time?! Why didn't you tell us sooner?"

"It was a promise to Cadance's father and Shining Armor," said Edward.

"Plus I didn't want to risk someone else wanting to harm Lady," added Shining Armor, "so it had to be kept secret; only Cadance knew."

"Where's Thomas and Spike?" asked Rarity.

"Oh, they'll show up any minute through the buffers," I said.

"Not so fast!" said a voice.

We all looked to find Sunset Shimmer, Trixie, and Lightning Dust walk into view. Apple Bloom, Sweetie Belle and Scootaloo huddled together nervously, Fluttershy squeaked in fright, and Flash glared angrily at them.

"What are you doing here?" he asked crossly.

"We want the Elements of Harmony," said Sunset.

"Why do you want them?" I asked, "But more importantly, how do you know they exist?"

"I read about them in a book," said Sunset, "and why do I want them? I want power!"

"Why should we give them to you?" Miss Celestia asked firmly, "You don't deserve them."

"If you don't," said Lightning Dust, "then we smash those magic buffers!" And she showed a sledgehammer, causing everyone to go into a panic!

"You wouldn't!" cried Toby.

"You must be mad!" exclaimed Rainbow Dash.

Suddenly with a whoosh, Thomas shot out from the magic buffers with his crew and Spike still on board.

"We're back!" he called to the others.

While this distracted the others, Sunset saw the opportunity to sneak behind Miss Celestia and grabbed the box containing the Elements of Harmony without anyone noticing her.

"Aha! There's the blue puffball!"

Suddenly Diesel 10 appeared, as if from nowhere.

"And look who he's with," added Discord.

"Spladge!" called Diesel 10, "Come and destroy!" The two shunters had been following Diesel 10 but stopped.

"No!" they said firmly.

"You do it yourself," said Splatter, "we don't like you!"

"We tired of you pushing us around!" agreed Dodge.

"Ah, who needs you, Spladge?" growled Diesel 10.

Edward rolled onto the line ahead of Diesel 10, much to everyone's shock.

"What are you doing, Edward?!" cried Gordon.

"Are ya trying to get yerself hurt?!" exclaimed Applejack.

"Leave them alone, Diesel 10!" Edward said firmly, "You don't have to do all of this and instead realize that steam engines and diesels are equal."

"Get out of my way, old tin kettle!" shouted Diesel 10, and without warning, he knocked Edward off the rails with his giant claw, much to everyone's horror!

"You big… ugly… MONSTER!" shouted Percy furiously.

"How dare you strike an innocent engine!" snapped Rarity.

At that moment, Chrysalis shot out from the magic buffers, landing on top of Diesel 10's roof!

"That makes three of us," grinned Discord.

"Run Lady, quickly!" cried Thomas, "And I'm going to help you!"

"So am I, Lady," said Shining Armor, jumping into Lady's cab, "I let you down once, and I'm not letting it happen again!"

"And I'm going with," said Cadance, joining her husband.

Thomas and Lady raced away.

"Watch out for the Big Dipper!" called Miss Celestia, "It's dangerous!"

"I'll get you, Shining Armor!" snarled Chrysalis, "And that engine too!"

"No you won't, Chryslais!" called Shining Armor.

"The magic you refuse to believe in will get the better of you!" added Cadance.

"Be careful!" I called with worry. Suddenly, Miss Celestia noticed something.

"The Elements of Harmony!" she cried, "They're gone!"

"Spike's missing too!" added Rarity.

"Oh no, he's still in Thomas' cab!" I realized. Then suddenly came an explosion and a beam of magical energy shot into the sky!

"What's that?!" exclaimed Apple Bloom.

The beam faded and floating towards us was…

"Sunset Shimmer?!" Fluttershy squeaked.

Sunset now had crimson skin, had a yellow, crimson and black sleeveless dress on, red devil wings, black boots, her haircut was spiked up, had a matching crimson and yellow tail, goblin ears, fangs, a gnarled horn on her forehead, and black eyes with cyan irises.

"Ah," she said evilly, "so much power, and it's all mine!"

Next to Sunset appeared what looked like Lightning Dust and Trixie transformed as well. Lightning Dust's form had wings like Sunset, but her body was green. Trixie's form also had a gnarled horn but her body was blue.

"The Great and Powerful Trixie is now even more Great and Powerful!" Trixie cried proudly. Lightning Dust rolled her eyes.

"I'll get you, blue puffball!" snarled Diesel 10.

"No you won't!" Thomas responded cheekily. Spike leaned out of the cab and blew a raspberry at the clawed diesel.

Up ahead, Diesel was shunting on a siding.

"Diesel!" called Diesel 10, "Help me take out those puffballs!"

"I may be devious, but I'd never hurt a person!" snapped Diesel, "So do it yourself!"

Diesel 10 snarled, his claw snapping wildly.

"Why do I have to everything around here?!" he snarled as they neared Henry's tunnel.

Thomas and Lady shot right through, but Diesel 10 had to lower his claw first. As they passed the washdown, Bowler could be seen covered in suds.

"Oi, Bowler!" called Diesel 10, "Wanna help destroy these puffballs?"

"Do it yourself!" sniffed Bowler, "Can't you see I'm being cleaned?"

"Grrr!" snarled Diesel 10. By now, he, Thomas and Lady were switched onto the branchline leading into Ballahoo.

"Hey Cadance!" Chrysalis called out, taking off her gloves, "The gloves are off!" and she threw them to the side and did some sort of fighting gesture.

Back at Vicarstown, Sunset and her transformed cronies were preparing their next move.

"Now that we're powerful," she said, "I think the first thing we should do it get rid of all these useless steam engines!"

"You're crazy!" exclaimed Henry.

"Ya don't say!" Trixie said psychotically.

"Steam will never vanish on Sodor!" said Rainbow Dash, "You may try and hurt us, but you'll never get rid of steam power!"

"That's a good idea," said Lightning Dust, "let's get rid of you six first!"

Sunset formed a large ball of magic energy in her hands and threw it towards us! The six of us huddled together expecting the worst. Everyone else shut their eyes!
