The British Rail Class 170 Turbostar is a British diesel-hydraulic multiple unit passenger train designed and built by Adtranz, and later by Bombardier Transportation, at Derby Litchurch Lane Works.
The Class 170 was derived from the British Rail Class 165 and 166 DMUs, known as the Networker Turbos, of the 1990s. The first units were introduced to service in 1999, shortly after the privatisation of British Rail; they have been commonly used to operate regional as well as long-distance services, and to a lesser extent suburban services. A total of 139 units were built, but some were later converted to Class 168 and Class 171 units. These trains are currently in use with CrossCountry, East Midlands Railway, Northern Trains and ScotRail.
