Train to nowhere

Standing inside one of the carriages of the steam train Martha looked around in amazement.
"It's bigger on the inside."
"Nah, just an optical illusion," replied the Doctor.
"They have a football pitch in one of the carriages! How do you explain that?"
"Maybe we aught to speak to someone who's knows what's going on..."
He grabbed one of the passing porters. "Excuse me who is in charge here?"
"Mr Orian."
"How do I find him then?"
"Oh, he will find you," replied the porter in an unsettling way.
"Hello," said a voice behind them. It belonged to a man with a thick bushy beard and ice blue eyes. "Can I help you?"
"I think you can Mr Orian," the Doctor flashed his psychic paper.
"And what does Scotland Yard want to talk to me for?"
