Oliver is a Great Western tank engine who works on Duck's Branch Line.

Bio in the Railway Series

Oliver worked on the Great Western Railway. Sometime during the 1960s, he ran away for fear of being scrapped with his coach, Isabel, and a brakevan named Toad. The three were forced to hide between signalboxes and rely on the goodwill of signalmen to pass at safe times. When control got wind of the runaways, they hid in an old quarry branch and had the cutting blocked by rubbish to avoid being spotted by the Diesels outside. The runaways decided it was safe to leave at some point, but before they could reach the greener pastures of Sodor, Oliver ran out of coal. Luckily, Douglas was able to rescue Oliver and hid him on a siding at Crovan's Gate. The Fat Controller soon found out and arranged for the three to be repaired and painted in Great Western colours. Toad decided to be Douglas' brakevan to thank him, and the Fat Controller rescued an autocoach named Dulcie and gave her to Oliver.

Oliver was then sent to work on the Tidmouth-Arlesburgh branch line, but became conceited after the big engines gave him their respect in recognition of his adventures and pushed his weight around, prompting several ballast trucks to push him into a turntable well. Oliver received little respect from the trucks after the incident, but got his own back by pulling the ringleader, S. C. Ruffey, apart. Oliver is now well-respected by the trucks, out of fear they will be pulled apart too.

Bio in the television series

Oliver and Toad were escaping from scrap when Douglas found, saved, and brought them to the North Western Railway. The other engines were impressed by his adventures and the attention soon went to Oliver's smokebox. He was so conceited that he ignored Duck and Donald's advice about trucks and several pushed him into the turntable well. Upon his return from the Works, Oliver regained his respect after pulling the ringleader of the trucks, S. C. Ruffey, apart. Oliver has since had many adventures, such as running Thomas' Branch Line during the engines' trip to England, discovering an abandoned house which was later turned into a tea-house, spending a night as a snowman after crashing into one in the village, and being saved by Emily when he was about to be hit by Thomas.


Oliver escaped the dreaded scrapyards of the Mainland, mainly thanks to Douglas, but also as the result of sympathetic signalmen, luck, and using goods only routes under cover of darkness, with some close calls along the way. Despite his previous heroism and daring feats, Oliver is an engine who is willing to admit every day is a learning curve. When he was still new to Sodor, he let the other engines' responses to his courage, resource, and sagacity from his amazing recounts of daring escapes and adventures get to his smokebox and he became conceited. However, when troublesome trucks pushed him into the turntable well, he grew into a much more humble, settled engine and was far warier of trucks. But later, with some help from his brake van Toad, he did gain much respect and authority among the trucks when he showed his strength with the ringleader of the trucks, S. C. Ruffey, a little more than he had perhaps been intending. Oliver still has gumption, but is now a more obedient, sensible engine. He feels his responsibility on the railway deeply, is ever thankful for being aided in his escape from scrap by Douglas, and is a trustworthy, tenacious, plucky engine. However, he does occasionally has one or two temper problems and grumbles quite easily (which has been correctly proven in Season 7), but despite this setback, Oliver is still one of the more really useful, and well-behaved engines on Sodor. 

Technical Details


Oliver is based on a GWR 14xx Class 0-4-2T. These engines were fitted with a mechanical system allowing the driver to control the locomotive remotely from the cab of an 'Autocoach', such as Isabel. They were originally assigned numbers in the 48xx series, but were renumbered into the 14xx series in 1946. Oliver's number comes from a real 14xx, No. 1436, which was built at Swindon Works in August 1934 as No. 4836 and worked in the West of England until it was withdrawn in October 1958. It was scrapped at Morkot Ltd., Caerphilly on the 30th of April, 1959. According to The Island of Sodor: Its People, History and Railways and Sodor: Reading Between the Lines, "It is doubtful whether this (1436) was the number actually allotted to him in 1946". Four engines of this class survive in preservation.


In the Railway Series, Oliver is painted in the Great Western Railway's Brunswick green livery with yellow lining, black wheels, brass GWR numberplates on the sides of his cab and a brass safety valve bonnet. Before he came to Sodor, he was painted in the British Railways Brunswick green livery, with a BR crest painted on the sides of his tanks. He carries two builder's plates on the sides of his cab.

In the television series, his paint had faded by the time he was rescued, leaving him in a rusty red colour. After his rescue, he was repainted in the North Western Railway's green livery with the 1934 GWR crest painted on the sides of his tanks and the number "11" painted on the sides of his cab in yellow.

"Oliver's no use at all; thinks he's very clever.
Says that he can manage us; that's the best joke ever!
When he orders us about, with the greatest folly,
We just push him down the well, Pop goes old Ollie!"
