Derek is a Diesel, best known for his initial "teething" troubles.
The Fat Controller realised Bill and Ben needed help 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 in Calling All Engines!, pulling a goods train up Gordon's Hill.
Derek is a jolly, enthusiastic Diesel engine, 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. But Derek is a likable 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.
Derek is based on a BR Class 17, a Clayton and Beyer-Peacock Diesel-electric Type 1.
Derek is painted in the British Railway's green livery with yellow warning panels.

- Derek was not named in his appearance in "Double Teething Troubles," he was only referred to as "the new Diesel". It was not until the release of the merchandise when his name was revealed. Originally, he 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.
- In 1999, the official website referred to Derek as "Paxman Diesel".
- Derek's theme is a rearrangement of Mavis' theme.
- Derek's problems were undoubtedly inspired by his basis, as the twin Paxman engines on the real Class 17's were unreliable, being prone to problems with the camshaft, cylinder head, and other areas.
