Derek (also known as Paxman Diesel) is a large green diesel who is known for his initial "teething" troubles.

Biography

The Fat Controller realised Bill and Ben needed help with their work and sent for Derek, but Derek's cooling system overheated on Gordon's Hill and BoCo had to come to the rescue. The news of the rescue went through the North Western Railway's rumour mill in due course until a confused Percy informed Bill and Ben that Derek had a toothache. Bill and Ben were apprehensive of Derek as a result but forgot their fear when Derek's cooling system overheated yet again and they had to help him home. Derek was then sent to the Works to be mended.

Derek returned later and was seen straining pulling a goods train up Gordon's Hill.[3]

According to the Official Website, Derek now spends most of his time at the quarries and clay mines near Brendam Docks working with Bill and Ben.

Personality

Derek is a jolly, enthusiastic diesel engine, keen on making an impression, who was brought in to assist Bill, Ben and BoCo at the China Clay quarry. Unfortunately, due to his engine, he is highly prone to teething troubles, namely overheating and suffering frequent breakdowns, for which he is apologetic for the inconvenience. As a result, he spends many a day having his engine tended to, which is unfortunate since he really wants to work hard. However, Derek is a likeable chap and even Bill and Ben decided that they liked him due to his friendly nature. Derek has an infectious charisma, is keen to help anyone around him and has a passion for sorting things out in a jiffy - if his cooling system lets him.

Technical Details

Basis

Derek is based on a British Rail (BR) Class 17, also known as the Clayton Diesel-electric Type 1. 117 members of this class were built between 1962 and 1965. Derek's problems were undoubtedly inspired by those of his basis, as the twin Paxman engines of the real Class 17s were unreliable, being prone to problems with the camshaft, cylinder head and other areas. Because of these problems, all Class 17s were withdrawn by the end of 1971, after less than 10 years of service. One Class 17, D8568, is preserved at the Chinnor and Princes Risborough Railway in South Oxfordshire, England.

According to David Maidment, Derek (then known as Paxman) was originally envisioned as a BR Class 14 (also known as the D95XX series, nicknamed "Teddy Bears") diesel-hydraulic locomotive.[4] Fifty-six of these engines were built at Swindon Works between 1964 and 1965. Some of these engines worked as bankers at Ebbw Vale and had a tendency to run hot, leaving the Class 37 diesels to pull both the train and the banker to the top. These incidents became the basis for the story of Derek's debut in Double Teething Troubles.[4] A total of 19 engines of this class are preserved on various heritage railways around the United Kingdom.

Livery

Derek is painted in the BR Deep Bronze green livery. He has yellow warning panels on his front and back ends. He has white lining on his window frames and he has the BR Ferret and Dartboard crest on his sides.

Trivia

  • Derek was the first non-Awdry standard gauge engine to be introduced into the television series.
  • Derek was not named in any of his appearances as in his debut episode, Double Teething Troubles: he was only referred to as the new Diesel, or simply Diesel and in the music video Trying, the lyrics say "Who's that straining up the hill?" rather than Derek's usual name. This makes him the first character to only be named in merchandise ranges.
  • Originally, Derek was going to be named Paxman, but it was changed for fear it would offend the Paxman brand of diesels, or refer to celebrity Jeremy Paxman.
  • The BR crest on Derek's ERTL toy reads "Thomas Tank" instead of "British Railways".
  • In his Wooden Railway prototype, Derek is seen with a greyish engine, unlike the black one presented in his final toy. His 2007 reissue sports the correct yellow engine.
  • Derek's ERTL prototype shows him with a darker and different face and a darker colour scheme. His second Ertl promotional artwork incorrectly depicts him with steam engine type wheels, a darker colour scheme, a grey undercarriage, square buffers and with no red buffer beam.
  • According to Sharon Miller, she wrote Derek into a sixteenth series episode with a non-speaking role.[5] Bust My Buffers! was the episode in which this was to happen, but it never materialized due to "Paxman" in the script being mistaken for "Paxton".
  • Derek's theme tune from Double Teething Troubles is an arrangement of Mavis' theme from the third series.
  • Derek is one of the few characters from the classic series to not get a Capsule Plarail model, along with Daisy, 'Arry, Bert, Bertram and the Horrid Lorries.
