Harvey/Behind the Scenes

Background Information
Harvey is a fictional standard gauge crane tank locomotive created by Jonathan Trueman.

Harvey first appeared in the sixth series episode Harvey to the Rescue, which first aired in 2002. His last appearance was in the twenty-fourth series episode A New Arrival, which was released in 2021.

Voice
Since his return in 2013, Harvey has been voiced by Keith Wickham in both the British English and American English dubs of the series. Keith Wickham gives Harvey a Scottish accent; reflecting his basis' origins.

Gauge 1 model
Harvey's models were scratch-built to run on gauge 1 track by model maker, Kenny Gittens. The models were made out of brass. They were painted in a matte finish and lined with yellow automotive pinstripe tape. The numbers and letters were custom printed stickers.

Two models of Harvey were built. Both were track powered, so pick-up contacts were attached to the metal wheels, which ran into the motor to power them. The electricity ran from the track to the wheels/pick-up contacts and went into the motor to power him. One model of Harvey was built for scenes where he had to move around, so his chassis had the motor inside it. The other was for scenes where he used his crane, so the motor was in the crane mechanism which was operated by a remote controller.

Harvey has had modifications throughout the model era. This includes:
 * Series 8:
 * His paint livery became darker.
 * Series 9:
 * In Thomas' New Trucks, he had a claw. He also used it in two scenes in the tenth series Learning Segment, Right Sized Engine for the Job.
 * Series 10:
 * One of his faces had more teeth painted to resemble a grinning face, but was not used on-screen until the twelfth series.
 * He regained his hook, excluding two scenes in the tenth series Learning Segment, Right Sized Engine for the Job.
 * Series 12:
 * His whistle sound changed.

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 set of models made in gauge 1 scale, Harvey's model would stay under HiT and later Mattel's ownership.

One of Harvey's television series models was on display at Drayton Manor with his happy face but was returned to HiT Entertainment in 2011. Sometime when Harvey was on display, his happy face fell off however it would later be put back on.

Faces
Ten different facial expressions were sculpted for Harvey, although only nine were used on-screen and the other, a sleeping face was left unused. The faces were first sculpted in clay and from that resin casts were made using a silicone mould. Two of Harvey's prototype faces are owned by the preservation group Top Props.

Close-up model
Close-up shots of Harvey's cab were required for scenes in where he had to interact with close-up scale figures. Most of the engine was built, excluding the wheels, and a visible face, however, only the back half of Harvey was shown on screen. Harvey's close-up model only appeared in the ninth series episode, Thomas' New Trucks.

CGI model
In 2009, the series introduced Computer-Generated Imagery (CGI) as a replacement for the show's long-standing live-action models. In 2012, Harvey was created in CGI by Nitrogen Studios, then transferred to Arc Productions. The model was "hand-sculpted" in Maya, a 3D animation and modelling software.

Harvey has had modifications throughout the CGI series. These include:
 * Series 17:
 * He gained permanent head and tail lamps.
 * He gained a brake pipe on his front and back, despite his basis not having one.
 * His coupling hook base was painted black instead of red.
 * His bufferbeam became the same colour as his body.

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