Background Information

Television Series

Nelson is a fictional ballast tractor created by Phil Fehrle and Robert Gauld-Galliers.

Nelson has not appeared in the television series since 2006.

Behind the Scenes

Live-action model

Nelson's model was custom built and painted in a matte finish with the numbers made from custom stickers. At a height of over four feet with his trailer. All of it was at 2 feet long at a 1:18 scale and weighed anything from 5kg to at least 15k.

Just like with Isobella and Buster, there were only two remotes built to control Nelson, one was used to control his movement, and one was used to move his eyes. His driving/steering remote was also shared with Patrick and was sourced from JR Propo's XP662 controller.

The eye mechanism had two servos, one for up and down movement and one for left and right movement. The up/down servo was attached to the body. The left/right servo had a rod attached to the arm, which connected to a bracket. The eyeballs were coupled to the bracket and locked in by the face-plate, so whenever the servos were powered, the eyeballs would move however the crew member desired.

Usage and Evolution
Present Day

In 2025, as part of Propstore's Thomas & Friends Online Charity Auction 2025, some of Nelson's faces would be put up for auction.

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 from 2010 till early 2011 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, Nelson's model would stay under HiT and later Mattel's ownership.


His driving/steering remote would also be listed for sale on the April 21st 2023 and sold a few days later.

In 2025, as part of the 80th Anniversary celebrations, Mattel would put Nelson's model, as well as 8 faces, up for auction as part of Propstore's Thomas & Friends Online Charity Auction 2025 in order to raise money for the National Autistic Society.
