Thomas

Details of Thomas' arrival on the North Western Railway in 1915 show he arrived by mistake. How this happened is unknown, but it is believed he was sent to Sodor in a wartime mix-up. His driver and fireman got along well with the local people and married Sudrian women. By 1920, neither one wanted to leave the Island or their beloved engine.

Through an inquiry, Sir Topham Hatt found out that the LB&SCR had written off Thomas as being "lost on war service". Rather than face complications resulting from a change in their books, the LB&SCR quietly sold Thomas to the North Western Railway for a "nominal sum".

Thomas formerly worked as the station pilot at Vicarstown, shunting trains for the bigger engines on the Main Line to take out. He enjoyed teasing the other engines, especially Gordon, who he would quietly sneak up on and whistle loudly while Gordon dozed in a siding. Eventually, Gordon managed to get back at Thomas by pulling out of the station before he could be uncoupled from his coaches, dragging him down the line at a tremendous speed. Thomas vowed to never tease Gordon again. Perhaps as a result of his brief excursion beyond his boundaries, Thomas longed to see more of the world and become a part of it and became jealous of the bigger engines for having the chance to pull trains.

On an occasion when Henry felt ill, Thomas took his morning passenger train since there were no other engines available, much to his delight. However, for unknown reasons, Thomas left the station before he could be coupled to his train, leaving behind the coaches, the passengers and their luggage. Thomas was not aware of his mistake until he was stopped by a signalman who asked where his train was. Ashamed and confused, Thomas returned to the station and collected his coaches. Subsequently, the incident made him a laughing stock among the other engines.

Thomas continued to grumble to the other engines, though they took no notice of him. However, Edward felt sorry for him and allowed him to take his goods train to Wellsworth while he handled his shunting duties in the yard. Although Edward had warned him to be careful around the trucks, Thomas took no notice and bumped the trucks as he started. When they reached Gordon's Hill, the trucks pushed him down the line, causing him to lose control. He only just managed to stop the train before hitting a set of buffers in Wellsworth Yard, where he was confronted by the Fat Controller. So that Thomas could learn about trucks almost as much as Edward, the Fat Controller kept Thomas there, continuing the swap with Edward, and could easily keep an eye on things, as he lives at Wellsworth.

While Thomas worked there, he saw the Breakdown Train. Shortly after he learned what its purpose was, James ran right past him, out of control thanks to his trucks, and derailed in a field west of the station. Thomas fetched the Breakdown Train and rushed to James' aid, helped to clean up the broken trucks and bring James back to the shed when he was re-railed. As a reward for his actions, Thomas was given two new coaches - called Annie and Clarabel - and the responsibility of running the Ffarquhar Branch Line, much to his delight.

Thomas loved his branch line dearly and had many adventures during his first days on the line. He once left his guard behind by accident and on another occasion he accidentally swallowed a fish in his tank when he took on water from the lake, causing him tremendous pain. During the autumn season, Thomas met Terence and teased him for his caterpillar tracks, though he soon came to regret this after he became stuck in the snow and had to be pulled out by him. Thomas later met Bertie and was challenged to a race to Ffarquhar. Although he was behind for most of the race, Thomas managed to overtake Bertie and won.

In 1960, Thomas crashed into the Ffarquhar stationmaster's house after a careless cleaner had meddled with his controls. Being unable to stop on his own, this incident taught Thomas that he still needed his driver to control him, as opposed to when an earlier compliment by his driver had gone to his smokebox. Thomas was sent to Crovan's Gate Works to be mended and received some changes to his design, including a new footplate that was now level from smokebox to bunker. When Thomas returned to the branch line, he began looking after the passenger trains with Daisy.

In 1990, Thomas was invited by the National Railway Museum to represent the North Western Railway in the Great Railway Show, an event showcasing many famous engines across the UK. Thomas was excited, but the journey to York was shaky; he damaged his front buffer beam when he hit a crossing gate and the lorry he was travelling on was booked for parking illegally. Thomas was repaired when he arrived at the Museum and befriended Green Arrow while he was being mended, though he continued to have bad luck when he ran into a bag thrown onto the line and frightened a small child. Fortunately, Thomas managed to make up for his bad luck when, as he was double-heading a rail tour with Green Arrow, he noticed the line up ahead was damaged and stopped the train. As a reward for his actions, Thomas was made an honorary member of the National Railway Museum and received a commemorative plaque. Afterwards, Thomas left York and returned to Sodor. When Thomas returned from York, he helped with building of the Harwick Branch Line.

In 1995, during the Golden Jubilee of the Railway Series, Thomas derailed on his branch line after rabbits had been undermining the track. He was rescued and managed to attend the Jubilee at Tidmouth albeit after being delayed at Knapford Junction after a set of points and a signal failed.

In 2007, during which Toby was having to handle the overflow of quarry workers, Thomas discovered an old carriage named Victoria, who he asked to be restored and help Toby. He brought her up from the Junction to Ffarquhar to meet Toby, after having to bypass Terence's toppled cart that had nearly blocked the line.

In 2011, Thomas had been crossing the river bridge near Elsbridge, when he was forced to stop due to an injured swan laying on the rails. He escorted it to Ffarquhar where it was taken to a vet and after recovery, Thomas brought it back to Elsbridge where the swan was freed. Later, he attended the Thin Clergyman's centenary. In the summer of that year, Thomas was upset about Stanley replacing Toby, but eventually came around.
