While high resolution detailing of both the covers can be seen, two promotional stills from the upcoming film have been published.
They both depict Thomas and Luke, one where the two cross paths on standard and narrow gauge tracks and another showing them hard at work.
The duo of images are set at the Blue Mountain Quarry location. The second however contains close glimpses of not only Thomas and Luke's drivers, but also a worker in the background.
