lines of the London Underground network, although in Underground Ernie's world, it is called "International Underground". Victoria (voiced by Janet Brown) is the oldest train, and is like a mother to the other trains. She wears a crown, to suggest the link between herself and Queen Victoria, but visually appears more like a caricature of the former Queen, Elizabeth II. Although Victoria is presented as the oldest character in the series, the Victoria line in real life is actually one of the newest lines – only the Jubilee line, opened in 1979, is newer. Bakerloo (voiced by Howard Ward) is an eccentric and has a deerstalker hat similar to that of Sherlock Holmes (the Bakerloo line used to terminate at Baker Street, where the fictional detective lived at number 221b) but has a profile resembling that of the Duke of Wellington, the victor of the Battle of Waterloo, after the Waterloo Underground station (Bakerloo is short for Baker Street & Waterloo Railway). Hammersmith (voiced by Tim Whitnall) is twin brother to City, a fast and furious train who is a general knowledge "whizz". He wears blue spectacles. City (voiced by Chris Jarvis) is Hammersmith's twin brother, and is also fast and furious, but is an expert in mathematics and finances (presumably a reference to the City, where many of the banks and financial businesses in London and the United Kingdom are based). He wears pink spectacles. Hammersmith and City are usually coupled back end to back and travel together as one train. Jubilee (voiced by Tim Whitnall) is the youngest train, and is into computers, music, internet, emails, games, and all the latest gadgets and technology. He can be mischievous, but is still well liked. Circle (voiced by Chris Jarvis) is a "hippy chick"—always helpful and rarely loses her cool. There are also five international trains, which Millie visits when she goes abroad every weekend. She always bring back exciting stories for Ernie, as well as a souvenir: Brooklyn (voiced by Howard Ward) is from New York City, is decked out in the American Stars and Stripes. Sydney (voiced by Emma Weaver) is from Australia, always wants to go to the beach. Moscow (voiced by Howard Ward) is from Russia. He is strong, fast and likes to clear snow off the tracks. He often uses the wrong word when trying to use various English phrases, such as saying "as fit
