Rex/Behind the Scenes

The Railway Series
Rex is a fictional miniature gauge tender locomotive created by the Rev. W. Awdry. He lives and works on the Arlesdale Railway.

He first appeared in the Railway Series book, Small Railway Engines, which was published in 1967. His last appearance was in Jock the New Engine, published in 1990.

Front of Rex:

Rex is based on the Ravenglass and Eskdale Railway's River Esk.

Television Series
In 2015, Rex was introduced in the special, Sodor's Legend of the Lost Treasure, along with Bert and Mike. Their appearances marked the first production since the fourth series to introduce engines from the Railway Series as new characters.

Rex is voiced by Tom Stourton (UK/US) in the CGI version of the series on both sides of the Atlantic, respectively.

CGI model
In 2009, the series introduced Computer-Generated Imagery (CGI) as a replacement for the show's long-standing live-action models. In 2015, Rex was modelled in full CGI by Arc Productions for the 2015 film, Sodor's Legend of the Lost Treasure. The model was "hand-sculpted" in Maya, a 3D animation and modelling software.

Rex's CGI model has a few changes from his original Railway Series design. These include:
 * Green wheels;
 * A grey running plate;
 * He now has a brakepipe and a lamp-iron.
 * He gained a headlamp above his smokebox;
