Terence (T&F)/Behind the Scenes

Background Information
Terence is a fictional crawler tractor created by the Rev. W. Awdry.

Terence first appeared in the first series episode Thomas, Terence and the Snow, which first aired in 1984. His last appearance was in the twenty-third series episode Diesel Do Right, which was released in 2019.

He appeared as a recurring character until the seventh series, and due to the stories focusing primarily on the Steam Team and the Narrow-Gauge engines from the eighth to sixteenth series, he was widely neglected and remained absent for a period of time, save for a minor non-speaking role in the special the Great Discovery.

When the show transitioned into full CGI in 2009, Terence was absent again for eight years. During his absence, in a 2015 interview with SiF, railway consultant Sam Wilkinson expressed his interest to reintroduce Terence into the CGI Series. In 2017, Terence made his return in the twenty-first series episode, Terence Breaks the Ice.

Voice
Since his return in 2017, Terence has been voiced by Tom Stourton in both the British English and American English dubs of the series. Stourton gives Terence a Liverpudlian accent.

Gauge 1 model
Terence's model was custom built from perspex for the first series. The model was built to run on Styrofoam road and was painted in glossy car body paint. The wheels and caterpillar tracks were sourced from a Tiger I tank model made by Tamiya. In order to save space inside of the engine, he was not fitted with an eye mechanism, and he had his eyes black-tacked into place.

Terence's model has had minor modifications throughout the the model series:
 * Series 2:
 * He gains additional black lines running across the sides of him.
 * At some point prior to being put on display at Drayton Manor he lost the black pieces next to the lower half his face.

Present Day
After production of the model series wrapped in 2008, most of the models and sets would be put into storage, with some being put on display at Drayton Manor Theme Park. All other models would be logged and referenced in 2009 by HiT Entertainment, from this HiT would decide on which models were to enter storage once again, which would be given to crew members and which to be disposed off. Due to only having one model made in gauge 1 scale, Terence's model would stay under HiT and later Mattel's ownership.

Terence's model was on display at Drayton Manor and was wearing his content face. His snowplough was broken around 2010 and his stack has snapped off, but were both repaired and glued in around 2019. In July of 2022 Terence was removed from the exhibit and returned to storage however during the construction of Drayton's Manor's new prop exhibition in 2023, Terence would be put on the layout alongside his happy face.

Faces
Four different facial expressions were sculpted for Terence, although only three were used on-screen and one of which a concerned face was left unused. The faces were first sculpted in clay and from that resin casts were made using a silicone mould.

CGI Model
In 2009, the series introduced Computer-Generated Imagery (CGI) as a replacement for the show's long-standing live-action models. Terence was recreated from scratch in CGI by Arc Productions/Jam Filled Toronto in 2016 for production of the twenty-first series. His model was "hand-sculpted" in Maya, a 3D animation and modelling software. Photographs of Terence's Gauge 1 model were used for referencing.
 * Terence had some modifications in the twenty-first series, including:
 * Losing his widow's peak and gaining eyebrows, making him resemble his facial appearance in The Railway Series from Toby, Trucks and Trouble onwards.
 * The lining running across his side is removed.
 * His engine is redesigned.
 * His treads are a slightly different design.
 * His face also became more elongated, covering his entire front and lost the small indents it originally had.
 * Gained rivets around his front.
 * His front fender disappeared.
 * His rear drawbar changed in style and he also gained a coupling loop on his front.
