Trackmaster Knapford Station Question

[Super]

Toys R Us exclusive, hmmm, would like to know more about that. Looking at some pictures, I found 3 sets (could there be more?) that has this Knapford Station, 2 that have the battery compartments and both are called Knapford Celebration, one with the special edition Celebration Thomas and one with Thomas, Stanley and Harold. Then there is the Thomas and Emily at Knapford Station that, looking closely at the box, looks to be the one I pictured above with no battery cover and green track numbers. If you can find a picture of the Toys R Us Exclusive edition or if anyone else knows of a different release of this Track master Station I would appreciate any info.
