Absolute Nightmare of a Steam Locomotive - Will it Run?

A few months ago I purchased a huge lot of British steam locomotives form eBay. Among them was this homemade 4-4-2 New British rail Atlantic steam locomotive which I suspect up until now was being used as some sort of decoration.

Who ever assembled this locomotive decided to spray some paint directly into the motor and all over the wheels which caused the entire unit to seize. During it's track test the motor finally gave out and I was left looking for a new solution. Luckily a train show over the weekend just so happened to have a replacement motor.

Although this locomotive turned out to be a bit of a nightmare to work on, I am happy with the results as it wasn't likely it would ever run again.
