Harold and Anna were flying through the sky, but even with Harold's strong light, it was extremely difficult to see where they were going.
"Anna!" Harold called over the howling wind. "Are you sure that Thomas will be okay?"
"Of course," Anna called back. "He will probably be lucky to have Elsa beside him."
"But will she be okay?"
"Of course, Harold," Anna answered. Then, she remembered the quarry. "Harold, do you remember back at the quarry when Thomas rolled off the cliff?"
"Yes," Harold answered. "Thomas saved himself using those ice-track things, right?"
"Yes, he did. My sister, Elsa, gave him that power. But he still could be in trouble if he lost those powers."
Harold peered into the swirling snowstorm. "Well, it's extremely hard to see where I'm going."
Meanwhile, Thomas was still stuck in the snow bank. Elsa was pacing nearby, still trying to think of a solution on their situation.
But now, Thomas was feeling colder. "E-e-ell-lll-ssaaa…" he shivered. "It's s-s-sooo f-f-free-eezin-ng…"
"Then I'll light a fire," Elsa suggested, and she began walking towards Thomas's cab. But when she climbed into Thomas's cab and opened his firebox door, she was shocked. "Oh, my goodness; your firebox is pretty banged up, Thomas. I don't think I can light a fire in this safely."
Suddenly, Elsa paused. "Wait," she said as she climbed down, "do you hear that?"
Thomas listened carefully. "I don't hear anything…" he shivered.
"I can hear a helicopter," Elsa explained. "But what kind of helicopter would be flying in this weather?"
"Helicopter," Thomas wondered. Then, his eyes lit up. "Wait; maybe that's Harold!" Immediately, Thomas began calling as loud as he could. "Harold! Harold, I'm here!"
Harold was almost directly above them, and he heard something. It was Thomas's voice, but it was hard for him to tell that. "I hear something," he said, "but I don't know what it is."
"Hold on, Harold," said Anna, "I hear it, too. Let's fly slower and maybe we can figure out what that sound is."
As Harold inched further, he began to hear Thomas's voice more clearly.
"Harold! Help me!" Thomas's voice called.
"That's Thomas!" Harold called out. "Maybe we can find him!" Immediately, he scanned the area with his searchlight.
Elsa noticed the searchlight peering through the storm. Then, she had an idea. Using her powers, she covered herself and Thomas with a large sheet of ice.
"What are you doing, Elsa?" asked Thomas.
"If the light bounces off the ice and returns to its source, that makes it easier for us to be spotted," Elsa explained.
And she was right. Anna noticed the light return to herself and Harold, and immediately, she knew what it was. "Harold!" she called. "We've found Elsa!"
"Then I'll find a place to land," Harold replied, and he slowly began to descend.
In a few minutes, Harold found a place to safely land. As soon as he was on the ground, Anna stepped out as Harold turned his engine off.
"Elsa?" Anna called. "Are you there?"
Elsa heard Anna's voice, so she called back, "Anna! I'm over here!"
Anna looked around, and through the swirling snowstorm, she saw her sister!
"Elsa!" Anna cried happily. "You're okay!" She ran over to her sister.
Elsa held her arms out, and Anna gratefully ran into them, hugging her.
"Oh, Elsa," Anna smiled, "I'm so happy you're okay."
"So am I, Anna," Elsa responded. She and Anna let go of each other so they could keep talking.
"So, do you know where Thomas is, or what happened to him?" asked Anna.
"Yes," Elsa answered. She began walking back a little bit. "He's right here."
Thomas was only a few dozen feet away from where Harold had landed, and they all saw what had happened to him.
"Oh, my," gasped Anna. "Thomas, what happened?"
"I fell off the mountain," Thomas answered weakly.
Harold and Anna gasped in shock.
"You… fell off the mountain?" asked Harold.
"Yes, I did," Thomas responded. "I don't think I'll ever be a really useful engine again because of that."
"But that wasn't your fault, Thomas," Elsa assured him. "All we have to do is get you back to Sodor."
"How can we do that?" asked Harold. "I can't lift Thomas; he's too heavy."
"No," Thomas agreed, "but Rocky can lift me; he's the Sodor Search and Rescue breakdown crane."
"Great idea, Thomas," agreed Anna, "but how can we get him here?"
"Let's just fly back to Sodor and get him," said Elsa.
"No, Elsa," Anna told her, "we can't do that."
"Why not?"
"Because there are no tracks that lead here from the Island of Sodor," Anna answered.
Elsa realized her sister was right. But Thomas had a thought.
"Wait a moment," he said, "'no tracks'…" He thought, and then he smiled. "Wait, that's it!"
"What's it?" asked Elsa.
"There are no tracks between here and Sodor," Thomas stated, "so we'll just have to make some!"
"How do we do that?" asked Anna. "That'd take a lot of time and materials to build the tracks that far."
"No," Thomas corrected, "not tracks with rails and ties; tracks made of ice." He looked at Elsa. "Elsa, you remember that you created those ice tracks leading to Sodor when I first came to Arendelle, right?"
"Yes," said Elsa.
"Then you can create tracks of ice leading to Sodor on your own using your powers."
"That's a great idea," agreed Anna.
"But how will I know what direction or elevation to generate them in, Thomas?" asked Elsa.
"We have a map," Anna suggested. "You can use it if you need to while we fly back."
"But we need that to find our way back, Anna," Harold reminded her. "And we shouldn't stay here longer than we have to. Sir Topham Hatt needs us to get back as soon as possible."
"Oh, yeah," Anna sighed. "What do we do, then?"
Suddenly, Harold had an idea. "Anna, I have something in my cockpit that will definitely help."
"Okay, Harold," Anna said, and she climbed into Harold's cockpit.
"It's in the glove compartment," Harold responded.
Anna opened the glove compartment, and inside, she found something. "Pilot radios!" she smiled. She took them out and walked out. "We can use these, Elsa," she told her sister.
"How will doing that work?" asked Elsa.
"While Harold and I fly back to Sodor, we can tell you how high or low and which direction to generate the ice tracks," Anna explained.
"That's a great idea," Elsa agreed. "Then let's do it!"
"Excellent!" Thomas smiled.
So Anna climbed back onto Harold, and they began to take off. But first, Anna looked at the map, and then she spoke to Elsa through the radio. "Okay, Elsa," Anna said, "I'll tell you if you need to change direction, elevation, or both. So until I do, just keep going in the direction you're going."
"Okay, Anna," Elsa responded.
"To start, have your tracks go in the same direction as we're flying, and keep them close enough to the ground for now." Harold and Anna flew off, and Elsa generated the tracks in that direction.
As Harold and Anna flew back towards Sodor using their map, Anna kept a close eye on the tracks as well as the route they were taking. Whenever there was an obstacle in the way, or whenever Elsa had to change direction, Anna helped her to safely navigate around the landscape.
At last, they came to the edge of the sea. Anna spoke back into her radio. "Elsa, we've reached the sea, so now we just have to cross it, and we'll get back to Sodor."
But Elsa was beginning to get tired out—Mount Everest was much farther from Sodor than Arendelle was, so she had to make her ice tracks go for much longer and further than the first time. "That's great, Anna," she panted, "because I'm getting tired."
"Well, once we get there, I'll let you know, and you can have a break. And since it's the ocean, until we reach Sodor, it'll be just fairly straight and even in elevation." With that, they all continued on their way.
By the time Harold reached the Docks, it was almost sunrise. Harold landed nearby, and Anna observed Elsa's ice tracks; she helped her connect them to the main tracks, just like a railway junction. As soon as they were connected, Anna spoke to Elsa once more:
"Okay, Elsa; you did it, so you can take a break now."
Elsa was very relieved to hear this. "Thank goodness," she panted. "I need a rest." She climbed onto Thomas's footplate and lay against his side, and she closed her eyes to get some sleep.
