TrackMaster Knapford Station Celebration Set???

[Super]

I am not much of a knower of Thomas stuff as I thought there was only one Trackmaster Knapford Station set. Did a little looking around after your question and it looks like there may have been 2 sets called Celebration, one with Thomas and the one you mention with Stanley, Harold and Thomas. These along with the Emily and Thomas at Knapford Station are now all I have ever heard of but of course you probably already knew that.
