Duck

Montague, affectionately known as "Duck" because of his supposed waddle, is a green pannier tank engine. Duck runs his own branch line with Oliver. He holds great pride in being Great Western and this results in him having a strong work ethic. This can, however, be a cause for friction with his colleagues, when he insists that his way is the only right way to do things.

Biography
Duck worked as the station pilot at Paddington before moving to Sodor in 1955 to take over Percy's shunting duties at Tidmouth, leaving the latter free to assist with the construction of Knapford Harbour. Duck was a hard worker, but the others mistook his work ethic for simplicity and tried to use this to their advantage. They soon found their mistake when Duck and Percy took revenge on them by barring them from entering the shed. Duck earned a reprimand from the Fat Controller for this, but so did the other engines, who were told, as Duck put it, that it is the Fat Controller's railway, and as controller, he is the one who gives the orders.

When Diesel arrived, the others took a liking to his flattery, but Duck was doubtful and left Diesel to his own devices, which resulted in the latter getting into a mishap with some old trucks. Duck tried to help Diesel when the trucks started to tease him, but to no avail. Diesel vowed to get revenge and inspired by several incidents occurring around the yard in Duck's absence, spread rumours that Duck had given offensive nicknames to the others. Duck was sent to work as a banker for Edward at Wellsworth pending further inquiry and after bravely stopping a runaway goods train at his own risk, he regained the respect of the others. Of course, by this time the others were aware that the matter was all Diesel's fault, but Duck's heroism certainly helped.

Duck would later show Donald and Douglas around when they arrived and they soon became friends. He also allowed Stepney to take a special visitor and helped him double-head a passenger train when Class 40 broke down from sucking an inspector's hat into his air-intake.

Personality
Duck is a Great Western pannier tank engine. His real name is Montague, but he is usually called Duck, which he prefers. This is said to be because he waddles, though he does not really. Duck knows how to hold his own and tends to stand for no nonsense from any engines that might get ideas above their station and try to order him or others about; as a result of this and his strength, most tank engines look up to him, though he has never gotten along particularly well with Thomas. However, his moral code is not perfect and often favours fairness to kindness. He enjoys running like clockwork, without problems, or interruptions, making him a very efficient and loyal engine, and he takes tremendous pride in the responsibilities bestowed upon him.

Duck is cheerful, busy and tends to bustle about. He is very proud of his noble Great Western heritage, often claiming that "there are two ways of doing things: the Great Western way, or the wrong way", occasionally to the annoyance of other engines. He strongly admires City of Truro and enjoyed talking "Great Western" with him when he visited the North Western Railway. He is also shown to be kind to others.

Duck is often welcoming of newcomers, even most diesels, in spite of having lies told about him by Devious Diesel not long after his arrival. He will often support the underdog, stick up for his friends and help others see the error of their ways. However, occasionally he does have the "Tank Engine sense" of teasing the bigger engines such as Gordon. Duck is also known to have a rivalry with James, but he has earned the respect of the bigger engines and has firm friendships with Edward, Percy and the Scottish twins.
