Rex (T&F)/Behind the Scenes

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

In 2015, Rex was introduced in the special, Sodor's Legend of the Lost Treasure, along with Mike and Bert. Their appearances marked the first production since the fourth series to introduce engines from The Railway Series as new characters. He last appeared in the twenty-fourth series episode Thomas and the Inventor's Workshop, which was released in 2021.

Voice
Rex is voiced by Tom Stourton in the CGI version of the series in both the UK and US dubs.

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 brake pipe and a lamp-iron.
 * He gained a headlamp above his smokebox.

In addition to his standard livery, a few other texture variants exist of Rex's CGI model. These texture variants include:
