Steam along Thomas

Is the Thomas Steam Along Tomy/Plarail or Trackmaster?

Mainly the former. The metallic version is a Motor Road and Rail version from two sets (one for UK/AUS and another for US), and the non-metallic is a Plarail version sold individually. The metallic version was later sold seperately in the original TrackMaster UK range, but nearly all the engines in that range were the same as their previous versions just in redesigned boxes. All of the Steam Along Thomas' are now long gone, 2005-2008.
