Thomas - Series 11/12 model history

The first appearance of the Series 11/12 model of Thomas was featured in Thomas and the Jet Plane due to the lighting being more warmer in the episodes starting as of Series 11, it gets to larger saturation to fit the color better.

The first picture is the book of Thomas and the Treasure.

The last picture is from the Series 11/12 Engine Roll Call song.

I recently got blocked from this Wikipedia for not listening to the rules and I tried making the history of Thomas, I know that my lifespan would be longer if this happens again.
