The following list describes the characters that have appeared in the British children's book series The Railway Series, along with the television adaptation Thomas & Friends, which ran from 1984 until 2021. The Railway Series is a series of 42 British books written by Wilbert Awdry and his son Christopher Awdry. Wilbert wrote the first 26 books from 1945 to 1972 beginning with The Three Railway Engines; while Christopher wrote the remaining 16 books from 1983 to 2011 concluding with Thomas and His Friends.

Unless otherwise said on this page, the technical notes come from actual notes laid out by Wilbert Awdry when he was developing the characters and setting for his stories; these notes are cited in his publication The Island of Sodor: Its People, History, and Railways.

Introduced in The Railway Series

Steam locomotives

Name	Number	Configuration	Description	First appearance	Based on
Thomas	NWR 1	0-6-0T	Initially worked as the station pilot at Vicarstown. After helping to rescue James from an accident, Thomas was rewarded by being promoted to run the Ffarquhar branch line with his two coaches, Annie and Clarabel.	Thomas the Tank Engine (1946)	LB&SCR E2 class (with extended side tanks)
Edward	NWR 2	4-4-0	Runs the Brendam branch line and is one of the oldest engines on Sodor.	The Three Railway Engines (1945)	Furness Railway K2 Class
Henry	NWR 3	4-6-0	Was originally built as a prototype Gresley engine and needed special Welsh coal. Following a major accident when pulling the Flying Kipper at night, Henry underwent an extensive rebuild, giving him a new shape to allow him a better performance.	The Three Railway Engines (1945)	LNER Gresley Class A1 (prototype) (old shape; Henry I) LMS Stanier "Black Five" (new shape; Henry II)
Gordon	NWR 4	4-6-2	Assigned to the Wild Nor' Wester express passenger train that runs from Tidmouth to London, but occasionally hauls goods trains, much to his disliking, as he believes that these are below him. He and the Flying Scotsman are the only surviving class (A1/A3)s.	The Three Railway Engines (1945)	LNER Gresley Class A1
James	NWR 5	2-6-0	Does not like pulling trucks and feels superior to the others except the big engines and is proud of his red coat of paint. James was an 0-6-0 experimental version of his class; he was initially painted black and built with wooden brake blocks that caught fire easily, resulting in a crash on his first day, prompting Thomas to come rescue him with the Breakdown Train. He was rebuilt into a 2-6-0 and given a red livery to cheer him up and now currently works on the Main Line as a special utility mixed-traffic engine, hauling passengers, goods, and occasionally the Wild Nor' Wester express.	Thomas the Tank Engine (1946)	L&YR Class 28
Percy	NWR 6	0-4-0ST	First brought to Sodor while Gordon, Henry and James were on strike against having to shunt their own coaches "like common tank engines", and later became the station pilot at Tidmouth.

When the BBC Television producers visited Sodor, Gertrude was filled with wires and instruments as part of the "Television Train".	The Little Old Engine (1959)

Culdee Fell Railway

The Culdee Fell Railway (CFR) is Sodor's only rack railway. It climbs to the top of Sodor's highest mountain, which shares the railway's name. It is based on the Snowdon Mountain Railway in North Wales, was opened in 1900 and for many years was operated under the direction of Mr. Walter Richards, the General Manager. The railway was only featured in Mountain Engines (1964). The engines on the line are all 0-4-2RTs.

Name	Number	Description	Based on
Godred	1	The original engine on the railway and is named after one of Sodor's historical rulers. Culdee tells the story about Godred in Mountain Engines: Shortly after the railway opened, he lost contact with the rack rail at a loosened rail joint and plunged sideways over a cliff. No one was injured except for Godred, who was so badly damaged that he was scrapped, with his parts being used to repair the other engines. This incident is based directly upon the Snowdon Mountain Railway's opening day accident when their No. 1 L.A.D.A.S suffered a similar accident.	L.A.D.A.S.
Ernest	2	Arrived in 1900.	Enid
Wilfred	3	Arrived in 1900.	Wyddfa
Culdee	4	The principal engine on the Culdee Fell Railway. When introduced in Mountain Engines, he had been overhauled in Switzerland between 1962 and 1963 and was on the last stage of his journey home. Culdee has great respect for dangers found on the line and relies on his coach, Catherine, to help him travel safety.	Snowdon
Shane Dooiney	5	Arrived in 1900. (Dooiney is Manx Gaelic for "man", cf Irish duine.)	Moel Siabod
Lord Harry / Patrick	6	Arrived in 1962 and was named after the manager. When he was new, Lord Harry was reckless and scared his coaches by taking risks. After he derailed and disgraced himself, Lord Harry was punished by having his name taken away. He asked for a second chance and was given a job of doing lowly shunting. He was fittingly renamed "Patrick" in honour of the climber who risked his life to help the others.	Padarn
Alaric	7	Arrived in 1962.	Ralph
Eric	8	Arrived in 1962.	Eryri

Name	Number	Description	First appearance	Based on
Neil	S&M 2	A tank engine with an unusual box shape, originating from the Sodor and Mainland Railway (S&M). In a flashback in Very Old Engines, he helped to transport Skarloey from Kirk Ronan Harbour to his new home at Crovan's Gate. He warned Skarloey about V-tipper wagons and they became friends. It is mentioned by Christopher Awdry in Sodor: Reading Between the Lines that Neil is still around but his whereabouts were unknown. In the book's second edition published in 2025, it was revealed that Neil had been found and donated by Richard Topham Hatt to the Crovan's Gate Preservation Society in 2023, the first rail museum proper on Sodor which was being helmed by the now retired Sir Topham Hatt III. Neil has operated at the new Crovan's Gate museum since then.	Very Old Engines (1965)	Neilson 0-4-0 box tank
Bloomer		A old Engine discovered by The Fat Controller in an old shed in Wigtownshire during the early 1970s, and attend the Shildon Cavalcade in 1975, which celebrated 150 years of the Stockton and Darlington Railway	Railways of Sodor (1976)	LNWR Bloomer Class

Bill and Ben	SCC 1 and 2	A pair of dark yellow 0-4-0 saddle tank engine twins belonging to the Sodor China Clay Co (SCC). They both work in the china clay pits, and at Brendam Docks, where they shunt trucks. Bill and Ben are Sodor's most mischievous engines, and they like teasing and playing tricks on the other engines.	Main Line Engines (1966)	Bagnall 0-4-0ST "Alfred" and "Judy"
Mavis	FQC 1	A privately owned diesel shunter who works for the Ffarquhar Quarry Co. (FQC). She mainly shunts trucks around the quarry's sidings. Learned how to keep the trucks in line thanks to advice from Toby.	The Railway Series: Surprise Packet (1971)	British Rail Class 04
Scruffey	N/A	A privately owned wagon, who worked for S.C. Ruffey & Co. Ballast Contractors. Kept in very poor condition by his owners. Like the majority of trucks, he was badly behaved and highly disrespectful towards the engines. This is exemplified by how he made a very rude song about Oliver's derailment in the turntable well whenever he saw the latter pass by. However, he received his comeuppance when Toad hatched a plan with Oliver to place Scruffey at the front of the train and sand the rails to give Oliver a firm grip when starting (acting on advice Stepney gave to Duck). By this time, Scruffey had already instructed the trucks to 'hold back', thus restraining the train from moving. This, coupled with Oliver's tractive effort at the front and Scruffey's poor condition, resulted in him being pulled apart. Following this, the trucks warn each other about what they perceive to be the consequences of teasing Oliver. Scruffey's ultimate fate varies between the Railway Series and the TV series. In the Railway Series, he is scrapped, having been deemed 'unserviceable before (he) came' by the Fat Controller, who then asks Oliver to help maintain discipline by keeping that information to himself. In the TV series, he is repaired, and remains silent.	Oliver the Western Engine (1969)	Various 5-plank wagons found across the British railway network

British Railways/Visitors

Various engines from British Railways (BR; also known as "the Other Railway"), and some from preserved/private railways and museums have visited the North Western Railway, both on regular trains to-and-from the mainland, for special events, or under a lease agreement.
