Bill and Ben (T&F)

"You know, I sometimes call them The Bees." "A good name. They're terrors when they start buzzing round."

- Duck and BoCo discussing Bill and Ben Bill and Ben are yellow saddle tank engine twins belonging to the Sodor China Clay Company. They work in the china clay works and at Brendam Docks, where they shunt trucks. For a brief time, they worked at Centre Island Quarry, where the task of keeping them in order fell to Mavis.

Biography
Bill and Ben made their first appearances listening to Percy recount the time he got caught in a flood helping Thomas, before being shooed off by Henry, as they were in a shed specifically for the Fat Controller's engines.

One day, Bill and Ben were sent to work in the yard. They got to use the turntable as a reward for their hard work, but they were both accidentally sent down the same track and they ended up buffer-to-buffer. They ended up blaming each other for the incident and refused to speak to one another. At last, Edward and BoCo lost patience and the Fat Controller heard about the incident. He gave the twins a chance to work together and sure enough, the plan worked. The twins started to speak to each other again. Bill and Ben sometimes found it dull up at the clay works and wanted something exciting to happen. They got their wish when a rockslide devastated the quarry. Luckily, Bill and Ben had taken all of the workmen and the foreman out of the quarry before the rockslide. The Fat Controller was so pleased that he called them heroes.

Later, BoCo could not handle the twins as much as he used to. This led to Sir Topham Hatt bringing in another diesel, Derek. Bill and Ben had heard from Percy that Derek had toothache, but they soon found out that Derek really had teething troubles. The twins and Derek had to pull a train the next day and Derek soon overheated. Together, the twins got the train to their destination. That night, they, BoCo and Duck talked about Derek all night long.

When Salty was sent to work with Bill, Ben and Mavis with an important job, he impressed them with his skills for handling the trucks. Unfortunately, the twins became jealous when they learnt that this was through him singing songs and telling tales of the sea and became even crosser when Salty told them stories. Luckily for them, Salty was transferred to Brendam Docks. Bill and Ben met Salty again when they themselves went to the docks and started teasing Cranky. This time, they encouraged Salty to tell them his stories, knowing that Cranky could not stand them. The twins spent the entire night being engrossed in and fascinated by Salty's many tales and when they left the following morning, Cranky was pleased. Afterwards, Ben had to get new buffers, so he was sent to the Works. Bill became jealous and his mind drifted away from his work. After some trucks teased him, Bill crashed through the buffers at the end of the track, falling into a ditch. Ben arrived to rescue Bill and Bill was taken to the Works to be mended.

Sometime later, Fergus was sent to help the twins at the quarry but they got tired of his "do it right" attitude. Bill and Ben collected a rock crusher from the docks and caused a rockslide. Fergus pushed them out of the way, but the twins returned the favour when they helped him out of the rocks.

In the seventeenth series, they teased Percy after he had an accident with a mailbag, unaware the pumpkins on their train were falling onto the tracks, which caused more problems for Percy. After Sir Topham Hatt ordered one twin to act as a back engine, Bill reluctantly went to push from behind. Ben ended up derailing near an embankment and Percy (although he was nervous because he had lost his new lucky charm) helped Bill pull Ben back onto the tracks.

After racing Connor several times (by racing, one would start the race and the other twin would be waiting at the finish), Sir Topham Hatt figured out their tricks. So people would not confuse the two or think they were the same engine, Bill was repainted blue. To continue the tricks, Ben tricked Kevin into giving him a blue coat of paint too. Since then they were repainted to their yellow schemes. They also teased Harvey about going fishing with his hook.

Thomas was sent to work with the twins at the Clay Pits while a bridge on his branch line was being repaired. They ran away from him and after he caught up, they teased him about being slow. They showed him to a line of trucks, which he was coupled up to. Thomas began pulling them but did not realise that Timothy was on the other end, jerking the little oil-burning engine backwards. Later that day, there was a storm at the Pits and the rain made the cliffs unstable. Thomas was near some cliffs and saw a set of mysterious footprints. However, the area was still unstable and he was unable to investigate. Bill and Ben pushed Thomas to safety just before the three were hit by a landslide. The next morning, the twins were congratulated by the Fat Controller. Later in the week, Thomas asked if they were playing a trick on him (he thought they were scaring him with fake footprints). However, Bill and Ben thought that he thought that their rescuing him was a trick and so they puffed away, offended. When Percy went to the clay pits to prove his bravery to James, Bill accused Ben of making puffing noises in his sleep and when Thomas came looking for Percy, the twins assumed that they could literally hear what Timothy was dreaming. When they went to work that day, they were almost hit by a landslide and after Marion found a fossil, Bill and Ben were both very intrigued by the concept of fossils.

In the eighteenth series, Bill and Ben played Guess What's In My Shovel with Marion. They also teased Timothy for being an oil-burning engine, but when the Clay Pits ran out of coal, Timothy went to pick up some more. They apologised for their teasing. However, they later sent Timothy on what the Fat Controller referred to as a "fool's errand" to search for a rainbow-coloured truck. Timothy brought back a green truck with several colours of paint on it full of dockyard waste. Bill and Ben were sent to take it to Whiff's Waste Dump as punishment, as well as being on waste duty. They also teased Emily and Samson.

In the nineteenth series, the twins became convinced that Timothy was no help at all. So when they found out that the Fat Controller was looking for an engine to help at Brendam Docks, they volunteered Timothy. Unfortunately, the twins were too busy messing around to work on their own property. Luckily, once Timothy was no longer required at the docks, he came back to the Clay Pits to help them clear up the mess.

In Sodor's Legend of the Lost Treasure, they teased Henry when he saw a ghostly rail boat on the rails the previous night, which was really Skiff.

In the twenty-second series, Harvey came to help them out when they had an accident. Rebecca was there to see Harvey arrive to help them and thought he looked cool with his crane. Later on Valentine's Day, Bill, Ben and Diesel teased Thomas and Rosie that they were a lovely couple, while Thomas and Rosie did not want to be embarrassed by the teasing.

Bill and Ben made up a game called "Hunt the Truck" and hid a truck for Nia. After Edward made them give Nia her truck, the twins attempted to get revenge on Edward by hiding his truck full of Christmas decorations and presents for Sir Robert Norramby's Christmas party. Edward knew what the twins were up to and took the truck from where they hid it. As a way to give them a taste of their own medicine, he pretended to be worried about losing the truck and how the party would be ruined, prompting the twins to go on a search for it. They eventually gave up and decided to apologise to everyone for what they did, only to run into Edward at the party and realise that he had taken the truck they hid and taught them a lesson on how it felt to have trucks hidden from them.

They were later seen in a queue of engines at Ulfstead Castle, after Percy told the latter there was to be a railway show there.

Personalities
Bill and Ben are Sodor's most mischievous saddle tank engine twins, who have great fun in teasing and playing jokes on other engines of the railway. They enjoy attention and love taking visitors and being photographed. They tend to work together, like most twins, but even this youthful pair can have their arguments among themselves and can squabble with one another - particularly about whose fault one of their follies was. They are highly prone to playing tricks and being cheeky. There is no real harm to them, but even Edward admits that they are maddening at times. Bill appears to be the quicker-witted leader, while Ben seems to be the follower of the pair.

Despite their cheeky and mischievous antics, if a dangerous event occurs, such as a rockslide, they are shown to be quick-witted and capable to act to rescue anyone in trouble. This was shown when they saved a group of workmen and Thomas from many rockslides. The two also usually try to keep their jokes from becoming harmful, and will show remorse if their cheeky antics go too far. Even though they like causing confusion and delay, like all engines on the North Western Railway, they want to be Really Useful.

Basis
Bill and Ben are based on the Bagnall 0-4-0STs "Alfred" and "Judy" of Par, Cornwall, who are both preserved and in working order at the Bodmin and Wenford Railway. According to the foreword of Thomas and the Twins, Alfred and Judy are both Bill and Ben's twins.

Alfred was once repainted yellow for a Days Out with Thomas event, to resemble Bill.

In the television series, Bill and Ben are twice the size of their basis'; Alfred and Judy. This was so their eye mechanisms and motors could be accommodated. When they returned to CGI, they were modelled in the same larger size.

Livery
Bill and Ben are painted golden yellow with red lining. Both have brass nameplates with yellow writing, the initials "SCC" painted on the sides in yellow and "BRENDAM BAY" on the front of their saddle tanks. In Buffer Bother, Ben has silver buffers, but returned to having black buffers afterwards.

From the seventeenth series onwards, the twins have red wheels instead of their original black. In the episode Bill or Ben? from the same series, the twins were painted dark blue with dark blue wheels, yellow lining and yellow lettering, but returned to their normal livery soon afterwards.

Quotes
"What's that?" asked Bill loudly. "Shh!" whispered Ben. "It's Gordon!" "It looks like Gordon, but it can't be. Gordon never comes on branch lines; he thinks them vulgar!" Gordon pretended he hadn't heard. "If it isn't Gordon!" said Ben. "It's just a pile of old iron". "Which we better take to the scrapyard!" "No Bill, this lot's useless for scrap! We'll take it to the harbour and dump it in the sea!" Gordon was alarmed. "I am Gordon! STOP! STOP!"

"I remember the first time I met those two", laughed BoCo. "They nearly made my eyes pop out! Edward soon put a stop to their games". "Edward is the only one who can keep Bill and Ben in-order", chuckled Duck. "I sometimes call them, the Bees". "A good name!" replied BoCo. "They're terrors when they start buzzing around!"
