One morning, confusion reigned amongst the engines.
For a new coal mine had been opened recently.
"Why is there another coal mine?" Percy asked his brother Edward.
"Percy, I have no idea." Replied Edward.
"Do you know Thomas?" Asked Percy.
No I don't." His best friend responded.
Percy was about to ask Gordon when he said
"Don't think about it Percy -we're as clueless as you are."
"Shouldn't we ask Sir Topham Hatt about this?" Duck asked.
"Well, that would be wise." Toby approved.
"Right, we need another deputation." Gordon declared.
"Oh no- not me!" squeaked Percy, darting into his shed to hide.
"No it wouldn't be you." Edward called. "I'll do it."
"What's all the commotion? The Fat Controller asked suddenly, who had driven up to the sheds to speak to them.
"Please sir, we were just wondering what the coal mine was for." Edward said.
"Yes- begging your pardon sir, but isn't the coaling plant enough for us steamies?" Duck inquired politely.
"Not quite. You see there are more steam powered locomotives and other machines on Sodor, so we need as much coal if you are all able to function properly."
The engines nodded. That sounded logical.
