Built in Leeds by Kitson, Thompson & Hewitson in 1855, the Queen was probably fast enough in the 50-plus years she ran on the Howrah-Raniganj line of the Eastern Indian Railway. In 1971, she became the first exhibit of the National Rail Museum, in whose grassy environs she stayed parked until 1996, when she was given a makeover by the Perambur workshop of the Southern Railway. The little green engine now tows a 60-seater passenger car on a seven-hour, 143km journey from Delhi to Alwar, on weekends between October and March. As the world&rsquos oldest functioning locomotive (certified by the Guinness Book of World Records), the Queen is now, as the Rail Museum website puts it, &ldquoa living legend, much older than the Titanic&rdquo.
