"This is going to be a real problem, Professors ," said the engine driver to Hogwarts Deputy Headmistress Minerva McGonagall and Headmaster Albus Dumbledore as they all stood on the platform of Hogsmeade Station, which serves both the village of Hogsmeade and the neighbouring Hogwarts School of Witchcraft and Wizardry. The GWR 4900 engine, used to pull the Hogwarts Express, was currently spewing out steam and groaning.

"What exactly happened, driver?" asked McGonagall. "Well….she hasn't been given an overhaul in over thirty years, and her safety valve, regulator, and gears are done for. They're not something we can just magic away. We'll need proper repairs without magic."

"Muggles are geniuses with their hands," said Dumbledore. "Are you saying we give the engine to Muggles, without them knowing where we got it, why it's coloured like this...we could break the Secrecy Statutes!" exclaimed McGonagall. "Yes, and it's the beginning of term soon. We'll need another engine. Preferably a steam engine too….the purebloods and the students love them," said the driver.

"I think I know where we can find a steam engine to pull our Express this September," said Dumbledore.

"Really?" asked McGonagall. "Remember those Caledonian engines, Minerva, who saw the Hogwarts Express whilst pulling a goods train together, in 1953?"

"Those two? Those jokers? We used Memory Charms on their crews, but they didn't work on those engines! How in the good name did engines become sentient?"

"I can hear you three talking," said the engine, getting annoyed.

"We're sorry, Helga," said the driver.

"Besides, there's only three Caledonian 812s left! How do we not know they weren't scrapped!"

"They weren't scrapped," said the driver. "They were sent to the North Western Railway, on the Island of Sodor, and still work there as utility engines. We could use either of them, both of them, or another part of the railway's fleet."

"How many engines?" asked Dumbledore.

"The two 812s we're talking about, a GWR 5700 0-6-0PT, a GWR 1400 0-4-2T, a GER D56- the last of its kind, a J70 steam tram, a BR Class 28, an SR USA Dock Tank 0-6-0T, a rebuilt Furness Railway K2 with 3500 Fowler tender and D49 cab, an industrial 0-4-0ST, a modified L&Y Class 28 2-6-0, a Billinton E2 with extended side tanks and a forward-dipped running plate-strangely enough, its back is straight, so it must have been either rebuilt or built like that by accident, a Stanier Black Five, an A1 Pacific that's going to be rebuilt into an A3, a GNR Stirling Single, an SR Q1, a BR Class 07, an LMS Ivatt 2MT, a DMU, a BR Class 35, a Dubs 0-4-0CT, two Class 08s, a GNR N2 and a battery-electric engine.

"All in all, about 25 engines."

"Sounds like a big railway-and Sodor's not that big, to tell the truth," murmured McGonagall.

"Still, it's a good place to look for an engine," said Dumbledore. "I'll have Snape go down and look for one and tell me which one is the best option. Hopefully, nothing will happen."

For those of you who don't know, these are the engines:

Industrial 0-4-0ST=Percy

Caledonian 812s=Donald and Douglas

DMU=Daisy

Class 35=Bear

GNR N2=Ryan

SR Q1=Neville

Ivatt 2MT=Arthur

SR USA Dock Tank=Rosie

BR Class 07=Salty

GNR Stirling Single=Emily

GWR 5700=Duck

A1/A3 Pacific=Gordon (they probably have the money to convert him, and he probably wants to)

Stanier Black Five=Henry (post-Flying Kipper rebuild)

Furness K2=Edward

GER D56=Molly

BR Class 28=BoCo

Class 08s=Sidney and Paxton

J70=Toby

L&Y Class 28=James

Dubs 0-4-0CT=Harvey

GWR 1400=Oliver

Battery-electric engine=Stafford

Billinton E2=Thomas
