It was exciting for the engines. There was going to be new engines joining the fleet. It was exciting for them all. "I wonder what classes they will be," said Max. "We'll find out when they get here," said Bertram.

The next morning, some whistles and horns were heard, and the engines looked to see steam and diesel engines coming towards them.

"Hello, I'm Alex."

"I'm Jack."

"Norvin."

"Rattler."

"Harold."

"I'm Barrow."

"And I'm Alison."

"Nice to meet you all," said Mallard, "I'm Mallard." "The Flying Scotsman." "Duchess of Hamilton." "Arron." "Max." "Perry." "Trooper." "Bertram." "Daniel." "Harry." "Steve." "City of Truro." "Nice to meet you all," said Rattler, "Now, can I please be shown how to work here? I've been told that there are some extra shunters needed here." Max and Perry smiled, and showed the diesel shunters around. "Now, Harry, could I learn the stations I need to stop at please?" asked Alison. "Of course," said Harry. "What about you Barrow?" asked Flying Scotsman. "High Speed, Non-stop express," said Barrow. "Really?" asked Mallard, worried one of them might get replaced. "Yes, don't worry, I'm doing it because there needs to be another connection to the south." "Oh," said Mallard, relieved. Soon, the engines started work.

Max showed Norvin the proper platform for the coaches, while Perry taught Rattler the way to handle trucks. Soon, the two engines had learned the ropes, and were getting used to their lives at King's Cross.

Harry and Alison double headed an express train heading north, and they soon became good friends. Flying Scotsman and Mallard each said their goodbyes to Barrow, who was double heading a stopping express with Steve to learn the stations. The diesels that watched it were disgusted by the sight. "Our revolutionary brothers," said one, "Working with scrap like that?!" "Disgraceful!" "What a horrid sight!" "I say we...." "You'll do nothing of it," said the station master, "These engines are preserved, and your shed masters and controllers will not be happy if you try to do something to these engines. I do not want any of the engines disgracing British Railways. This industry is already on it's knees, so no tricks!" "Yes sir," said the diesels.

The new engines all worked hard with each other. Jack and Alex helped bring goods and shunted trucks in the goods yard, while Harold worked at the coal mine with Trooper. Soon, the engines got together, even if there was some friction between some visiting engines. "You're a traitor to diesels everywhere!!" "And how am I?!?" asked Barrow. "You needed help from scrap iron!" "He's a steam engine!!" "Same thing!" City of Truro then bashed the diesel, and looked right at him, and said, "LISTEN HERE, CHOCOLATE BAR ON WHEELS, THIS IS MY FRIEND, AND IF YOU THINK YOU CAN BULLY HIM AND GET OUT OF HERE WITHOUT A SCRATCH ON YOUR PAINT, THINK AGAIN!!!! GET THE NEXT TRAIN OUT OF KING'S CROSS, NOW!! I DON'T CARE IF IT'S A GOODS OR PASSENGER, JUST GET OUT OF MY SIGHT!!!!!!!!!" The diesel rattled away in fear as fast as he could. City of Truro sighed, and looked at Barrow. "Wasn't that a bit over kill?" asked Barrow. "No," said City of Truro, "it's the only way that they'll listen. These boastful diesels are really testing my patients."

At the coal mine, a class 40 diesel was collecting a load of coal, and was about to take off, when Harold stopped him. "Where do you think you're going?" he asked the diesel. "Um, over to Scotland." "Not without a break van you don't." The diesel laughed, "I don't need a break van, I have special breaks that allow me to apply all the breaks on the trucks and coaches!" "What kind of bull excuse is that? Stay right there, I'll find you a break van. Leave it to the likes of a tank engine to change you big engine's diapers. How typically typical." Harold then steamed off to find a break van. The diesel grew impatient. "OH COME ON PIPSQUEAK, I'M GONNA BE LATE!!!" "Better late than never, Big Oaf." The diesel sighed, "This is gonna be a long day."

At King's Cross, many diesels were impressed that there were diesel shunters. "Now these are proper engines. About time they got rid of those relics." Norvin and Rattler were not too happy with their attitude. "If you're referring to our friends," said Rattler, "I suggest you watch your mouths." "Why, is that City of Truro gonna come and beat us?" The big diesels laughed, until Norvin said, "Yes, we'll tell him the exact things you said, and he will track you down until you become scrap." The diesels soon stopped laughing. They then waited for the guard's whistles, and then headed off.

Just then, Alison and Steve came back from the South coast. "Phew," said Alison, "Are the runs always that fast?" "Yes they are," said Steve, "Get used to it, cause you'll be doing mixed traffic services with me and Arron."

Soon, the engines all talked about their day, and Harold said, "I just don't understand these diesels being so barbaric. Not taking break vans. It's so primitive." "I know that, but many of them don't need them," said Max. "It's still stupid." "I agree," said Arron, "I would never pull a heavy goods without a break van." The engines talked endlessly of the old days of steam, and soon fell asleep, thinking of what was to come.
