Duck

Montague (affectionately known as "Duck" because of his supposed waddle) is a Great Western 
pannier tank engine. He has his own branch line. 
Duck has two Great Western autocoaches named Alice and Mirabel, as well as three Great Western Slip Coaches collectively nicknamed "Slippies". 
==Bio in the Railway Series==
Duck worked at Paddington before moving to Sodor in 1955 to take over Percy's shunting duties, 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 the shed. Duck earned a reprimand from the Fat Controller for this. 
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 at Wellsworth pending further inquiry and after bravely stopping a runaway goods train at his own risk 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 continued working on the main line until 1967, at which time the Tidmouth-Arlesburgh branch line - nicknamed The Little Western - was restored and Duck was asked to run it with help from Oliver and, on occasion, Donald and Douglas. 
==Bio in the television series==
Duck had pretty much the same start in the television series as in the original book series. Duck and Percy often worked at the harbour. The workload eventually got too heavy and the Fat Controller had brought Diesel to help. Duck and Percy were furious and went on strike until the Fat Controller made them work again. When Diesel pushed some trucks into the sea, he was sent away. Duck and Percy gladly did the work alone. Duck often liked to watch the boats sail at Brendam. One day, a regatta was being held and Duck wished he could sail to faraway lands. Percy and Harold ignored Duck's remarks. When a man had hurt his hand, Duck brought him to Bertie, who would take the man to the hospital. Thanks to Bertie's remarks at Duck for flying along the rails, Duck now knew that rails could take him as many places as water could. 
Duck has had many adventures, such as: Helping Stepney take the express to Crovan's Gate after the Diesel broke down, supporting Oliver when he took on S. C. Ruffey and the other trucks, went to the Big City with the engines after they received a letter from a little girl, and tried helping Henry with getting the Flying Kipper up Gordon's Hill, but ended up crashing into it after the tail lamp fell off. 
Later, Duck was trapped at the docks with the big engines and Cranky. A tramp steamer crashed into the shed causing the shed and Cranky to topple over while also causing the engines to be trapped. Luckily, Thomas and Percy rescued them. Afterwards, George refused to let Duck get his truck off the Main Line, resulting in Gordon crashing into it. Duck was spared punishment when the Fat Controller was told George was to blame for Duck not clearing the Main Line before Gordon came through. 
Sometimes it appears Sir Topham Hatt has deputized Duck on other places on the railway. He has been seen in various yards along the mainline and Edward's Branch Line doing mostly goods work. 
During one hectic summer, Sir Topham Hatt was not sure how to handle the number of passengers traveling on his railway. Duck suggested bringing slip coaches, which he had used on the Great Western Railway, on the island. However, James lied and used the idea as his own, initially receiving praise only to cause trouble. Duck soon took control of the slip coaches and things worked out perfectly, with the coaches now appearing to be used year round. 
==Persona==
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. He likes things to run like clockwork, without fuss, and is a very efficient, loyal engine. He takes tremendous pride in the responsibilities bestowed upon him, particularly in his role of running his own branch line with Oliver, sometimes known as the "Little Western" as a result. 
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 frustration of other engines. 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, Oliver, BoCo, and the Scottish twins.
