Bert (T&F)/Behind the Scenes

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

In 2015, Bert was introduced in the special, Sodor's Legend of the Lost Treasure, along with Rex and Mike. 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 The Great Little Railway Show, which was released in 2020.

Voice
Bert is voiced by Keith Wickham 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, Bert 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.

Bert's CGI model has a few changes from his original Railway Series design. These include:
 * Blue wheels.
 * A grey running plate.
 * He now has a brakepipe and a lamp-iron.
 * He gains two additional round windows on the front of his cab. The red lining that was originally present on his cab is also absent.
 * He gained a headlamp above his smokebox.
 * Akin to his appearance in Jock the New Engine, his wheels are outside his frames. His wheelbase is also much longer.

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