With construction beginning in 1997, the Turbostar family of diesel multiple units are by far the most numerous design of such units introduced to the privatised railway. Over the next fourteen years, over a hundred units belonging to this family have been built at the Derby Litchurch Lane works of Adtranz/Bombardier Transportation to operators across the country. They have become a recognisable sight across the network, sharing many design similarities with the Electrostar family of electric multiple units. Today they can be seen from the north of Scotland to the south coast, conveying passengers on many local and long-distance services. This book takes a look at the varied services undertaken by Turbostars, covering both past and present operators.
