 The earliest royal coaches date back to the mid-19th century in the reign of Queen Victoria; until an upgrade in 1977 there were multiple sets based in different regions, a legacy of the pre-nationalisation era of railways in Britain.Many are now in museums or on heritage railways; the National Railway Museum in York has a royal themed exhibition.Dedicated locomotives have never traditionally been part of the Royal Train, first appearing in special livery only in the 1990s, but also seeing use on other trains since 2003.
