Meanwhile, back at the magic buffers, in an all-familiar whistle, rainbow flash, and bell ringing, Thomas finally emerged from the Magic Railroad. He puffed away from the magic buffers, heading off down the line, and he whistled happily as he puffed off towards the grotto.
"I see him. Here he comes." Velma called after looking through some binoculars to try and spot him.
"Guess he was a little bit behind us." Sheeva took a guess.
"AHA!" A horrid voice suddenly called out from down upon the mainline, and this made everyone all freeze in horror, Sheeva and Scorcher holding onto their daughter, Braedey and Rose both holding hands, just as Thomas pulled up to the grotto behind Lady. "There's the blue puffball!! And look who he brought!"
Lady and Burnett were both in shock. They both knew who owned that voice. It was Diesel 10 himself, now rounding the bend, with his claw raised and armed, ready for the attack, rolling forward like a tiger ready to ounce upon its prey!
"It's D-D-D-D-Diesel 10!" Shaggy and Scooby yell out.
"Slodge! Come and destroy!" Diesel 10 now ordered to his lackeys as he rolled forwards.
However, both Splatter and Dodge stopped where they were, no longer wanting to work with Diesel 10. "No, no. You do it yourself. We don't like you. Yeah, we mean that. Emphatically. Yeah, what does that mean? I have no idea. It's a good word." They talked to each other.
"If Diesel 10 gets to Lady, it's game over!" Scorcher now said to the others. "We need a plan, and fast!"
"Run, Lady! Quickly! And I'm going to help you!" Thomas said in alarm.
Burnett suddenly leaped into action as he got into Lady's cab. "So am I, M'Lady." He said to the little purple and gold tank engine, patting her side gently. "I won't let you down." With that, he began to operate Lady's controls, getting her ready.
"Rose, come on!" Braedey called, he and Rose now jumping into Thomas' cab.
"Braedey Martin, what are you doing?!" Daphne cried out.
"Saving a steam engine's life!" Braedey declared, Scooby now jumping into Thomas' cab, Scorcher climbing aboard Lady.
"Let's do this!" Scorcher declared, Burnett nodding back.
"AHH, who needs you, Splodge!!" Diesel 10 roared to his two former lackeys, not bothering to deal with with one of them as he got closer to the two steam engines go ahead, him while opening and closing his claw, ready to attack, ready to pounce.
Sure enough, Lady began to move away from the grotto. "Burnett! Watch out for the viaduct! It's starting to collapse!! It's dangerous!" Mr. Garcia called out to Burnett, remembering what was happening at the bridge.
"Roger that!" Scorcher called back as Lady puffs away first.
"We'll keep Lady safe!" Braedey called as Thomas soon chuffs away from the grotto in a cloud of steam.
Diesel 10 raced by with a roar of his engine, laughing evilly as the others jumps back, then they all turned to Mr. Garcia when he suddenly screamed unexpectedly.
"What's the matter?" Casey asked.
"Why did you just scream?" Daphne inquired.
"Yeah. What's the problem?" Fred asked, sounding calm and collective. "Thomas, Braedey and the others are gonna get Lady away from Diesel 10, and they'll be just fine." He pointed his thumb to down the track that the three engines just took.
"Don't you all understand?" Mr. Garcia now sounded worried, which he doesn't sound like often. "'Lady'. That Lost Engine's name is Lady." Everyone now looked down the line. "She's part of the clue to the source of our magic-"
"-and the Gold-Dust!!" Casey and Mr. Garcia call out in unison, and in three seconds, they scream out in fear!!!
"Zoinks!/Jeepers!/Jinkies!/Oh, no!" The gang and Scorcher's family cried out. "Braedey! Rose!" Willow cried. "Scooby!" Shaggy yelled in worry.
Sure enough, Diesel 10 was in hot pursuit of both Thomas the Tank Engine and Lady the Lost Engine, the two tank engines up ahead and chugging at speed, steam rising into the air, while the BR Class 42 diesel has his hydraulic claw raised and ready to strike.
"Now, I'll catch you, Burnett Stone!" Diesel 10 roared, him chases both Thomas and Lady down the line, while Braedey, Rose, and Scooby were onboard Thomas' cab, with Burnett and Scorcher both onboard Lady.
"No, you won't." Burnett yelled out to the villainous British mainland diesel. "Because the magic you refuse to believe in will get the better of you!" He added in.
"You'll never catch us, Diesel 10!" Scorcher called back at the BR Class 42 locomotive, then he goes and shovels more coal into Lady's firebox to keep her going. "Not now, not ever!"
The three engines were flying along at speed down onto the mainline, the three engines now headed towards a nearby road bridge that passes over their track, the two tank engines going as fast as they can, Diesel 10 hot on their tail.
"You can run, but you can't hide!!! Right, Pinchy?!" Diesel 10 laughed evilly, snapping his claw twice, his engine roaring as his wheels pound against the tracks. Then, as he got much too close to Thomas, he lowers his claw at him, ready to take a snap. "Pinchy's hungry!"
"Rikes!/Yikes!" Scooby and Rose cried.
"Whoa! Get back!" Thomas cried, and he goes faster, gaining some ground away from Diesel 10.
"Kick it into high gear, Thomas!" Braedey called out, adjusting the tank engine's regulator.
Lady was too scared to say anything as she looks back, and both Burnett and Scorcher sense this. "Come on, Lady." Burnett coached to his little tank engine, patting the side of her cab in a gentle comfort.
"You got this, you mighty engine." Scorcher coaches as well.
Lady's wheels whirred like the wind, her traction rods and pistons going through the paces as she accelerates as fast as she could as she, Thomas and Diesel 10 power on under the bridge, continuing on down the line.
"Coming, Puffball!" Diesel 10 called out to the two steam engines, laughing evilly, as he chases on after both Thomas and Lady, even passing by the watermill. "Look out!" He taunted.
Back on the mainline, Henry was just making his run along with a heavy goods train, having just gone through the tunnel of his namesake. As he was making his way along, he saw Thomas with a little engine racing at high speed on the opposite track, and Diesel 10 was chasing them both!!
"Oh, no!" Henry whistled out before he began to puff away as fast as possible to warn the other engines about what's going on. "I've got to hurry!"
Further down the line, Thomas and Lady both continue on, the two of them soon raced through Henry's Tunnel just up ahead, the same tunnel structure Henry had just gone through a few moments ago. They charge through, the clouds of steam floating above the tunnel's mouth as they go through.
"Here I come! Duck, Pinchy!" Diesel 10 told his claw, and it lowers itself down in response, just as Diesel 10 enters the tunnel after moment after the two tank engines, his evil laugh echoing from inside the tunnel walls.
After exiting Henry's Tunnel, Thomas and Lady both struggle to gain some distance between them and Diesel 10, as he surged forward after them. Both Scorcher and Braedey onboard the two tank engines comic to shovel coal and adjust controls to help them run away as fast as they can. They race on down the mainline at speeds that the express could only reach, and both showing no signs of stopping anytime soon.
"I like my lunch STEAMED!!" Diesel 10 taunted the two engines as he got closer, and laughed evilly at his own joke, then he growled at them through clenched teeth, his claw raised to strike down.
"Keep going!" Rose said to Braedey.
"I am! I am!" Braedey insisted back.
As Thomas and Lady's wheels whirred like the wind and pound against the rails as they charge on, the two tank engines and the monster diesel race over an overpass bridge. As they do, James saw the three race by overhead, as he was pulling a goods train.
"What was that?!" James asked in shock. He then whistled out to Thomas, understand the situation as he accelerated off to go and find the other engines.
Back with Thomas, Lady, and Diesel 10, they race on down the line at high speed. Lady was puffing faster than she's ever gone before for some time, but she wasn't going fast enough to get away from Diesel 10. She could only look back while she keeps going.
"It's okay, Lady. You're going great. Just keep going, and don't stop." Scorcher coached to the little tank engine, and patted her side.
Braedey kept shovelling coal into Thomas' firebox, all the while with Rose doing her part to help. She, Burnett, and Scorcher now look or lean outside of their engine cabs, and they all now see Lady and Thomas had gotten ahead, but Diesel 10 wasn't giving up as he continued to chase after them.
"Huh. Pretty fast, for a puffball." Diesel 10 oddly complimented to them, and he tries to go faster to keep up with them, but they keeping the gap.
"Keep going, Thomas!" Rose called. "You're doing great!"
Meanwhile, over at the Big Dipper viaduct, the main span section in the centre of the bridge was struggling to hold itself up under its own weight. Some sections of the stone arch and keystones started to come loose, and they fell into the ravine below. It was only a matter of time before the main span section gives way.
Soon enough, Thomas and Lady rounded the bend, and they were now approaching the viaduct at speed. Onboard the two engines, their occupants could see the bridge up ahead, and they remember the warning Mr. Garcia said to them before they departed from the grotto.
"Well Lady, this is your shining time too." Burnett said to his engine, and gently patted the side of her cab.
"I hope so." Lady replied softly with a small smile on her face.
"This is it." Scorcher hunkers down for the trek across the viaduct.
Thomas and Lady's wheels whirred even faster, as they charged towards the bridge. Scooby and Rose both hold on tight as Braedey adjusts the regulator and reverser, him leaning out to see the bridge up ahead.
"Come on, Lady! Little engines CAN do big things!" Thomas coached to the little tank engine, as he and Lady now come up onto the viaduct, and they begin to cross it.
"Here we go!" Braedey said, and he and Rose held on tight.
As the engine's weights were being pressed down onto the rails of the bridge, the keystones and the stone in central span of the bridge began to break apart, and they began to split from the middle section of the viaduct, the span about to come apart. Lady charged on over the middle section, her wheels whirring and pistons puffing as she crosses over. But as she did, the stones in the central section now fell into the ravine, now leaving the tracks now suspended over a 10 metre gap above the ravine like a tightrope!
Thomas charges on ahead, his wheels crunching against the rails, Scorcher and Burnett looking back, the former watching in concern. Braedey, Rose, and Scooby all hang on tight as the blue tank engine now approaches the exposed span and tightrope tails. Thomas, as if he weighed no more than a human, amazingly crossed the gap without breaking the rails, and as he gets clear, both sides of the arch section fell into the ravine, leaving the tracks unsupported from below like tightropes spanning the two.
"We... we made it!" Rose cheered.
"We're alive!" Scooby announced.
"Yes, we are!" Braedey smiled.
"Well done, Thomas!" Burnett cheered out to Thomas, as both he and Lady got off the viaduct and continue on down the
"You amazing little engine! You made it!" Scorcher called, then he blew Lady's whistle in cheer. Thomas smiled and he whistled back, the two tank engines puffing away from the viaduct.
"Wait. What about Diesel 10?" Rose now questioned as she looks back.
Back over at the viaduct, Diesel 10 charged across the viaduct to catch up with the two tank engines, but as he does, he now saw the damaged section of bridge up ahead, plus the tightrope rails, and the huge drop down into the valley below.
"Huh?" Diesel 10 immediately slams on his brakes, sparks now flying from his wheels. "Who-what's going on? Whoa-ho-ho-ho!!" He tried to stop before the edge gap, but with his weight and inertia, it was already too late. As his front bogie wheels and front section came up onto the section of unsupported track of the bridge, the entire piece of track immediately gave way under his colossal weight, and Diesel 10 fell forward, cab over wheels, into the ravine below!! "AAAH!!!"
But then, his hydraulic claw amazingly managed to grab onto a sleeper on the other track, and he held on tight, Diesel 10 hanging over the ravine being held up by nothing but his own claw holding onto the sleeper.
"Phew. Puffball!!" Diesel 10 cried out to Thomas, hoping he might hear, as he hanged by only his claw over the span. Down below, unaware of what was going on overhead, there was a tug pulling a barge under the bridge. "Keep on!" Diesel 10 now pleaded to the sleeper, but the sleeper gave way from his weight, and Diesel 10 plunged into the ravine!! "COME ON!!!" He yells out, then he landed in the sludge barge below with a deafening crash!!
As the tug continued to pull the barge down the river, oblivious of what just happened behind it, Diesel 10 sat in the barge, unable to move or even do anything. His engine was heavily damaged, his bogies and wheels are broken and damaged, while black sludge rolled down his sides, and his claw was too heavily damaged and broken from the fall to move at all.
Diesel 10 groaned out in pain from the crash, but as he lay there, he tried to think of something positive out of this unlucky experience. "Huh. Oh, well. Nice time of the year for a cruise." He laughed to himself, as the tug continued on his way down the river, still oblivious of what had happened behind it...
