British Rail Class 165
The British Rail Class 165 Networker Turbo is a fleet of suburban diesel multiple unit passenger trains (DMUs), originally specified by and built for the British Rail Thames and Chiltern Division of Network SouthEast. They were built by BREL York Works between 1990 and 1992. An express version was subsequently built in the form of the Class 166 Networker Turbo Express trains. Both classes are now sometimes referred to as "Networker Turbos", a name derived some three years later for the project that resulted in the visually similar Class 365 and Class 465 EMUs.

The class is still in service, now operated by Great Western Railway and by Chiltern Railways. When operated originally by Network SouthEast, along with that operator's Class 166 trains, the Paddington suburban units were initially known as Thames Turbos, while the units operated on the Marylebone suburban network were known as Chiltern Turbos.
