If original is the first ever 2007 TrackMaster Toby by HiT Toy Company, then it the mainstream US release in Little Friends by himself with a half straight track piece. Next would be the more exclusive US 3-pack with Henrietta and the Troublesome Truck which did not change its cars the following year unlike other engines. The Little Friends Toby was then re-released without the track piece in 2009.
Whilst the 2012 TrackMaster by Fisher-Price Toby was first sold in Toby's Electric Co. Delivery, the Little and Big Friends releases updated soon after as well, with the Big Friends still retaining the blue van.
