Although I don't really like the Thomas and Friends series anymore as a whole, due to being grown up, I still have happy memories of when I was still into the series. And I still like the engine prototypes the characters are based on.
In addition to the many characters of Thomas and Friends that I was fascinated by, one of my childhood hobbies was creating lots of my own fictional engine characters. Although most of them were one time appearance characters.
I made a story about them or I drew them, but that was it. A lot of them were forgotten over the years as a result. However I still have some scrapbooks of some of them, or copies of stories about them, so some of them are still remembered, even if they only made one appearance.
But here's a list of my "inner circle" of fictional engine characters, their basis's, when they were built, and how fast they have been reported to go. Some of these engine characters I created as a child, and some of them I created when I had already officially grown out of Thomas and Friends but wanted to reawaken the happy memories and times that I had enjoyed as a child.
I discovered the Fletcher Jennings Class C, LB&SCR E2 Class, LMS Fowler Class 3F, LNER Class A4, Bagnall 0-4-0ST, Midlander 4wDM, Hunslet Austerity, British Rail Class 08, BR Class 42 "Warship", and British Rail Class 17 because certain engines of Thomas and Friends - Skarloey, Thomas, Jinty, Spencer, Bill and Ben, Rusty, Wilbert, Diesel, 'Arry and Bert, and Splatter and Dodge, Diesel 10, and Derek - are based on these classes.
Although I have officially grown out of Thomas and Friends, I still haven't completely abandoned it permanently. This is partly due to my interest in characters, and my interest in locomotives. The rest of the classes that are featured here I discovered in 2010 while reading through this book of locomotives, with the exception of the , BR Class 03, and BR Class 20 which I discovered sometime in 2017. Enjoy! :D

- ↑ This is how fast Wilbur is known to be capable of going. It is unknown if other engines of his basis are capable of reaching the same speed. If so, then this may or may not be the fastest speed Wilbur can reach. It all depends on how fast his basis in real life can go.
- ↑ Leander is actually named after me, but because I don't wish to reveal what my name is in real life, he is referred to on the internet as Leander because of the type of locomotive he is based on, and so it makes a suitable alias to use for him.
