There in the shadowy sidings of the Mid-Sodor scrapyards was a little narrow gauge engine. He had been through a lot, through wars and battlefields and trouble on his old railway.
When the railway closed down, the engine was immediately sent here where he would be cut up and later melted down.
The engine knew that it would be a matter of time before his life would end with the cutter's torch, so he made a plan.
The engine had combat experience and weaponry experience. He knew that he could use those abilities in order to save himself and have his revenge on Duke. He believed that Duke was the reason for what he went through.
Though during his time on Mid-Sodor, he had been equipping himself with some guns used in the great war (plus some modern day ones). This included the chemical gas stored into his sanding gear.
While he was at the scrapyards, he had been mending himself. Now his wheels are nice and even and he can go on the tracks more easily and derail less. When he saw the cutter's torch coming to him, he put his plan into action.
With a gust of smoke, he sprayed chemical gas right at the cutter's face. As he fell to the ground, The little red engine made his move. Others tried to stop him, but it was no use. Stanley used his weapons against all of them.
Then a prototype diesel shunter blocked the line, expecting him to stop. But the little engine didn't stop. He just opened the regulator to full and without a second thought, derailed the big locomotive. The big engine was severely damaged, but Stanley made it out of the scrapyards with only minor scrapes.
"See you for the first time in ages for the last time Duke.", he said.
