LEGO Train Models

The early Lego train series of sets were developed in Germany. Many of the sets in the grey era were modeled after or inspired by prototypes in use by the Deutsche Bahn (yellow/red for electric trains, black superstructures over red running gear for steam locomotives). A few sets have been based on other prototypes – for example the French TGV trains and Austrian "Krokodil" engine.

More recently, sets modeled after United States trains have been released, reflecting the introduction and subsequent popularity of LEGO Trains in the US: the Santa Fe Super Chief(10020) and Burlington Northern Santa Fe (10133) Locomotive.
Lego also modeled the fictional Hogwarts Express (4758) under the Harry Potter license, although the model is neither powered nor does it use the correct type of wheels to be a true LEGO Train model. In 2005, Lego offered a 9V motorized Hogwarts Express, (10132), which was discontinued in 2006.
