Montague (affectionately known as "Duck") is a cheerful and busy pannier tank engine from the Great Western Railway.
Duck was brought in originally to replace Percy as station pilot at the Big Station when the workload became too much. Formerly of Paddington, he is very proud of being Great Western, and has tried tirelessly to instill this ethos into the minds of his fellow engines – often to their annoyance. But Duck will stand no nonsense from anyone, be it trucks, coaches or engines and throughout his time as the Big Station pilot, he had the yard running like clockwork. Eventually, his hard work merited him the chance to run his own branch line on the Arlesburgh line, which runs down the coast to meet the Small Railway Engines and carry both ballast and passengers. He now works this line with the help of Donald, Douglas and Oliver, another Great Western engine.
