British Rail Class 165

Class 165/0

Thirty-nine Class 165/0 Turbo trains were built in 1990-91, in two batches, for the Chiltern subdivision of Network SouthEast, numbered 165001-039. Both 2-car and 3-car variants were built. Initially, thirty-three units were ordered (comprising the vehicles that made up units 165001-165022 and 165029-165039) but an additional order was placed for a further six units (165023-028). Units 165001-028 were delivered consecutively, as 2-car units, whilst units 165029-039 were delivered as 3-car units. These vehicles have a top speed of 75 mph (121 km/h). They are now all fitted with tripcocks for working over the London Underground lines between Amersham and Harrow-on-the-Hill, although upon delivery this equipment was only fitted to 165006-028. Automatic Train Protection is also fitted, making them one of the few classes to have both these features 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 DMOSL+MOS+DMOS. Individual carriages are numbered as follows:^[1]

• 58801-58833 (units 165001-022/029-039) and 58873-58878 (units 165023-028) - DMOSL
• 55404-55414 (units 165029-039) - MS
• 58834-58866 (units 165001-022/029-039) and 58867-58872 (units 165023-028) - DMOS

Class 165/1

No.165119 at Didcot Parkway. This unit is painted in the original Network SouthEast livery.

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 (145 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 DMOCL+MOS+DMOS. Although still listed on the vehicle data sheets at DMOCL vehicles, the first class area has been removed from 2-car 165s operated by GWR (the 3-car units were similarly de-classified, but this accommodation has now been re-instated as First Class), as such these vehicles are now technically DMOSL vehicles. Individual carriages are numbered as follows:^[1]

• 58953-58969 - DMOCL
• 58879-58898 - DMOSL changed from DMOCL in 2015^[4]
• 55415-55431 - MOS
• 58916-58932 and 58933-58952 - DMOS

Two coaches of no. 165115 were destroyed in the Ladbroke Grove rail crash. The remaining driving motor carriage remains as a spare vehicle.^[5][6]

Chiltern lines

Chiltern Railways refurbished three car Class 165/0 No. 165032 at London Marylebone

The 165/0 units were originally delivered in Network SouthEast livery for used on routes including fast services from London Marylebone to Princes Risborough and Banbury and local services from Aylesbury to London and Princes Risborough. In this role they replaced the Class 115 DMUs. They were later used further afield, when Chiltern services were extended to serve Leamington Spa, Solihull and Birmingham Snow Hill.

In December 1993, due to a downturn in traffic as a result of the recession, units 165001-007 were transferred from the Chiltern lines of Network SouthEast to the Thames lines (from Aylesbury to Reading depots). All vehicles had their tripcock equipment removed before transfer. The following year, unit 165007 was returned to the Chiltern lines, followed by 165006 in 1995. Due to unavailability of tripcock equipment upon their return, the units were coupled cab-to-cab and operated for some months between the vehicles of other units as semi-permanently formed four car units - until tripcock equipment became available, allowing them to be restored to operational two car units. Following privatisation, two former Chiltern units (165003 and 165005) were repainted into Thames Trains livery. Chiltern Railways inherited 34 Class 165/0 units from Network SouthEast, and the remaining five others were returned 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 were displaced and are now found less often on expresses to Birmingham, generally working on shorter routes such as stopping services to Aylesbury, High Wycombe, and Stratford-upon-Avon and also the Birmingham Moor Street - Leamington Spa local services.

A new depot was built at Aylesbury in 1990/1991 for the maintenance of these trains and has been enlarged since British Rail days, with the addition of a wheel lathe. Light maintenance and refuelling is carried out at Wembley LMD and Tyseley TMD and units can occasionally be found at Stourbridge LMD. Units are also regularly stabled in the Marylebone station environs, Aylesbury South Sidings and at Banbury, where a further depot is currently under construction at the south end of the station on the western side of the line.

All Chiltern units were refurbished between late 2003 and early 2005.^[3] 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 high back seating. The existing 3+2 low back 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. A further refurbishment commenced in 2015, concentrating on the toilet areas, to make these units fully Disability Discrimination Act 1995 (DDA) compliant for operation beyond 2020.

Thames lines

First Great Western Class 165/1 No. 165106 at Reading

The Class 165/1 fleet were built for local services from London Paddington along the Great Western Main Line; their main destinations included local trains to Reading, Greenford, Newbury, Bedwyn, Oxford, and Banbury, and services along the branch lines to Windsor & Eton Central, Henley-on-Thames, Marlow and Bicester Town.

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 that had been transferred from the Chiltern lines. In April 2004, operation of the Thames Trains franchise passed to First Great Western Link. 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.

In January 2010, First Great Western announced an £8 million refurbishment programme for its fleet of Classes 165 and 166 Turbo DMU trains:^[10]

• seats re-trimmed
• interiors repainted
• Passenger Information Displays replaced with a GPS-based system
• upgraded lavatory facilities
• flooring stripped and replaced

In 2012, First Great Western took delivery of Class 180 Adelante units for Cotswold Line service, and three-car Class 150 Sprinter units for Reading to Basingstoke Line services, allowing Class 165 and 166 units to be used to reinforce Thames Valley services.^[11]

In late 2015, as part of the rebranding to GWR, the Class 165 fleet had all first class sections removed to increase capacity.^[12]

Bristol lines

165132 arrives into Gloucester on 14 July 2018 with a Swindon to Cheltenham Spa service. In preparation for the service between Cardiff and Portsmouth, the coaches have been lettered D and E (pictured) for reservations.

All the Class 165s (alongside the 166s of which majority have already transferred) are due to transfer to Bristol and move allocation to St Philip's Marsh depot. This is to be able to strengthen and provide better capacity in the Bristol area ^[13], which will allow most of the current fleet in the Bristol area to move further west. It is planned that in the future, the service between Cardiff Central and Portsmouth Harbour will be operated by a five coach train (a 3 car 166 and 2 car 165 coupled together). Because of this, the 2 car 165s will have lettered coaches with one coach being coach D and the other will be coach E, of which 165132 has already received. Alongside the 166s, the 165s are to operate on the Severn Beach line, Bristol to Exeter line, Golden Valley line, Heart of Wessex Line and Wessex Main Line.

On 1 July 2018, the first 165 (165132) came into service in the Bristol area, operating the 2041 Bristol Temple Meads to Cheltenham Spa service. Since then, other units have came into service in Bristol and started service on some of the above lines around Bristol, alongside the 166s. It is planned that in some point in 2018, they are to start service between Cardiff and Portsmouth in their five coach formations, however they are currently not cleared beyond Southampton Central.
