The British Rail Class 165 Turbo diesel multiple units (DMUs) were built by BREL at York Works from 1990–1992. [2] These units are suburban trains, with an express version appearing later in the form of the Class 166 Turbo Express trains. The Class 165 Turbo belongs to the Networker family of trains.

Description
Two batches of units were built for different subdivisions of Network SouthEast to replace elderly "Heritage" DMUs as well as locomotive-hauled trains on services out of London Paddington and London Marylebone. The fleet are wide-bodied to take advantage of the gauges of the former Great Western Railway and Great Central Railway on whose lines they run. As such they are restricted to these lines.
Both have a 350 horsepower (260 kW) Perkins 2006-TWH diesel engine on each car, Voith Turbo-transmissions, and Gmeinder final drive.
When new, the units were branded as either Chiltern Turbo or Thames Turbo between the two first class windows of the DMCL carriage.
Class 165/0
Thirty-nine Class 165/0 Turbo trains were built in 1990-91 for the Chiltern subdivision of Network SouthEast, numbered 165001-039. Both 2-car and 3-car variants were built. Units 165001-028 were delivered as 2-car units, and were followed by eleven 3-car units numbered 165029-039. These vehicles have a top speed of 75 mph (121 km/h). They are fitted with tripcocks for working over the London Underground lines between Amersham and Harrow-on-the-Hill. Automatic Train Protection is also fitted, making them one of the few classes to have this feature in Britain.
165029-039 were temporarily allocated to the Thames line in 1992. This was necessary as resignalling of Paddington station meant that Network SouthEast could no longer run locomotive-hauled trains to and from Paddington. Insufficient numbers of Class 165/1 Turbo trains had been delivered by this date to operate all the locomotive-hauled services, so all the 3-car Class 165/0 Turbo trains were diverted to the Thames line as replacements. Once sufficient Class 165/1 Turbo trains had been delivered, 165029-039 were returned to the Chiltern line.
Each unit was formed of two outer driving motors, with an additional intermediate motor in the 3-car units. The technical description of the formation is DMSL+MS+DMS. Individual carriages are numbered as follows:
- 58801-58833 and 58873-58878 - DMSL
- 55404-55414 - MS
- 58834-58866 and 58867-58872 - DMS
Class 165/1
Thirty-seven Class 165/1 Turbo trains were built in 1992 for the Thames line subdivision of Network SouthEast, numbered 165101-137. Like the Chiltern units, both 2-car and 3-car variants were built. Units 165101-117 were delivered as 3-car units, followed by the 2-car units 165118-137. They are re-geared and fitted with bogie yaw dampers to allow top speed of 90 mph (140 km/h), more suitable for mainline use.
Each unit was formed of two outer driving motors, with an additional intermediate motor in the 3-car units. The technical description of the formation is DMCL+MS+DMS. Individual carriages are numbered as follows:
- 58953-58969 and 58879-58898 - DMCL
- 55415-55431 - MS
- 58916-58932 and 58933-58952 - DMS
Two coaches of no. 165115 were destroyed in the Ladbroke Grove rail crash. The remaining driving motor carriage remains as a spare vehicle.
Operations
The 165/0 units were originally delivered in Network SouthEast livery for used on routes including fast services from London Marylebone to Princes Risborough, Banbury, Leamington Spa, Solihull and Birmingham Snow Hill, and local services from Aylesbury to London and Princes Risbough.
Two units (165003 and 165005) were later repainted into Thames Trains livery.
Chiltern Railways inherited 34 Class 165/0 units from Network SouthEast, and the remaining five others were transferred from Thames Trains in 2004 - leaving Chiltern Railways operating the whole subclass.
After privatisation they continued to work similar services as before, but with the arrival of the faster Class 168 Clubman units the 165 Turbo trains have been pushed down the pecking order, are found less often on expresses to Birmingham, instead generally working on shorter routes, such as stopping services to Aylesbury and High Wycombe.
A new depot built at Aylesbury for the maintenance for these trains has been enlarged since its inception during British Rail days. Light maintenance and refuelling is carried out at Wembley LMD and Tyseley Depot. Units are also regularly stabled at Marylebone and Banbury.
All Chiltern units were refurbished between late 2001 and early 2005.[2] Air conditioning was added and the opening hopper windows replaced with sealed units. A new passenger information system similar to that on the Class 168 Clubman trains, CCTV cameras, and an area designated for the use of wheelchair-users were added, and the first-class section was removed as Chiltern became a standard-class only railway in 2003. The original 3+2 seating at the outer ends of the driving vehicles was replaced by new 2+2 seating. 3+2 seating was retained in the centre areas of the driving vehicles and throughout the centre vehicles of the three-car units. A cycle/wheelchair area with tip up seats was also added to each unit.
Thames lines
Class 165 Turbo trains were built for Network South East to replace elderly "Heritage" DMUs, and locomotive-hauled trains on services from London Paddington along the Great Western Main Line - known as the 'Thames line'
Their main destinations included local trains to Reading, Greenford, Newbury, Bedwyn, Oxford, Banbury and Bicester, and services along the branch lines to Windsor and Eton, Henley-on-Thames, Marlow and Greenford.
Following privatisation of British Rail, the franchise was won by the Go-Ahead Group who operated it as Thames Trains from 1996 to 2004 and inheriting the all the Class 165/1 Turbo trains as well as the first five Class 165/0 Turbo trains produced. As part of the franchise change they introduced a new blue, white and green livery. There were two variants of this livery; the Class 165 Turbo carried the non-express variant.
In April 2004, operation of the Thames Trains franchise passed to the First Group, who operated the company as First Great Western Link. The livery remained the same, but First Great Western 'Link' branding was applied over the Thames Trains logo.
In 2004, due to deliveries of new Class 180 Adelante units on sister company First Great Western, the five Class 165/0 Turbo units became redundant and were transferred to Chiltern Railways.
During 2007, the Class 165/1 Turbo trains were re-liveried with the First Great Western Neon Dynamic Lines livery.
In future it has been proposed to run the Class 165 Turbo alongside Class 150 and the express variant, Class 166 Turbo Express trains on the Cardiff Central to Portsmouth Harbour route, subject to line clearance.
