Double Teething Troubles AB Remake

Bill and Ben, the tank engine twins, work hard at the clay mines and quarries near Brendam Docks. While their work is very important, it can get hot and dirty for the twins, which in turn makes them naughty.
One morning, Bill and Ben were feeling very naughty indeed and they soon begin arguing over who has the rights to a line of freight cars in front of them. BoCo, who overheard the argument, rolls up to the twins and tries to break up the quarreling and warns the engines that the bickering will lead them into trouble, but the twins ignore him and collide into each other and derail at the points when they both try to take the cars. Sir Topham Hatt, who saw everything, intervenes and warns Bill and Ben to behave better. He then decides to bring in a new diesel to help them out, in the hopes that the diesel will give the twins the necessary help they need, all while making a good impression. BoCo also quietly suggests that the twins should just simply get back to work right away. Meanwhile, Sir Topham Hatt begins to have some doubts about his own decision; he is concerned that the new diesel may have some teething troubles and could cause more confusion than assistance.
Sit Topham Hatt was right; the new diesel, whose name is Derek, arrives on Sodor and is having issues while going up Gordon's Hill. While he manages to get halfway up, his engine coughs and breaks down, causing black smoke to billow out of his exhaust. BoCo is then called in to rescue Derek, who apologizes for the breakdown and explains he has teething troubles. The news soon spreads and Thomas tells Percy about Derek's teething troubles but Percy misunderstands Thomas, and thinks this means the new diesel has a "toothache." Percy then tells Bill and Ben about Derek and wishes them good luck, as they know they need another engine to help them out. The twins' manager then arrives and sends them to take their loads of clay to the docks, where they will be resting for the night as there is a lot of hard work to be done in the morning.
It was dark by the time the twins reach the docks. Feeling exhausted, they leave their freight cars by the quay and scurry off to the sheds, where Duck was waiting for them. Duck is quick to notice the twins' worried looks and after hearing about the diesel and his "toothache", Duck corrects them and explains that "teething troubles" means that Derek is a newly built diesel and is prone to have frequent breakdowns, which (in his case) is his cooling system. The next day, Bill and Ben prepare a train of clay cars and have just finished when they hear an unfamiliar sound. The twins soon realize that it must be Derek, who it turns to be as he arrives at the Clay Pits and helps the twins with the long train of China Clay cars by pushing from behind. However, during the journey, they come to a hill and another breakdown from Derek occurs from overheating. Bill and Ben are cross but ultimately, they end up pulling the diesel and the cars all the way to the docks.
That night, Sir Topham Hatt arrives at the sheds and congratulates Bill and Ben for their hard work and explains that Derek is sent back to the works. The twins agree to manage their work alone and apologize to BoCo for being rude and explain that Derek was very friendly. Then, Duck explains that friends always say goodnight to each other, and so they do, but all four engines still talk about Derek and his teething troubles all night long.
