Plarail Thomas was first brought to the US as the Battery Operated Rail System in 1997
Percy, James, and Henry were available with track in "Accessory Sets" - I haven't found any photos of them
They started using Tomica World packaging the next year in 1998 (Sometimes they even used UK boxes with a sticker over the European Tomy information with the US info on it)
I don't have any boxed Tomica World engines, but I do have the two sets pictured plus a TW Thomas Starter set

I have a website where I have been writing about and photographing many of the sets and pieces that I find interesting.
