Thomas the Train Toys

'Thomas'-based merchandise has proven very lucrative. At least five different categories of trains and tracks exist: "Take Along Thomas" with grey tracks; Tomy battery-operated engines with blue tracks; Brio-type wooden engines with wooden rails and roads (by ELC and others); electric model railway (produced in O gauge by Lionel, HO/OO gauge by Hornby and Bachmann and N gauge by Tomix); and Lego engines and tracks; along with complementary videos, DVDs, books, games, puzzles, stationery, clothing and household items.
