Gauge 1 model
Production orthographics were drawn up for Dennis' gauge 1 model on 13th July 2004. Dennis' model was scratch built from plastic to run on gauge 1 track, whilst his wheels and chassis were constructed from CNC. A second model was planned to be built however this model was never completed and was left unused.

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. Dennis' unfinished second model, would be disposed off by HiT Entertainment as it was no longer needed. The main first model however, would stay under HiT and later Mattel's ownership.

Dennis' model is currently in Mattel's storage unit in Southampton England. The second model was previously owned by a private collector after being rescued from the HIT skip in 2009 but was sold to Prop Gallery in 2022 and was painted up and completed to look like the original prop with the plan to be sold off later in the year.
