British Rail Class 314 alternating current (AC) electric multiple units (EMU) were built by BREL York works in 1979. They were the third variety of British Rail's then-standard 1972 design for suburban EMUs, which eventually encompassed 755 vehicles and five classes (Class 313/314/315/507/508). Able to operate from 25 kV overhead line only, the fleet works inner-suburban services on the Strathclyde rail network in Scotland. The class can run to a top speed of 70 mph (113 km/h).
Sixteen Class 314 3-car units were introduced in late 1979 to operate on the then newly opened Argyle Line and were used on both this and the North Clyde Line routes until October 1999, when the scrapping of most of the elderly Class 303 stock resulted in them being transferred to Cathcart Circle services. The Class 314 was based on the experimental Class 445 or "PEP" unit, the design of which spawned the sister Class 313 and Class 315 units which are used extensively in the London commuter area.
In line with the other PEP-based classes, the Class 314 units consist of two outer motor cars with an unpowered trailer vehicle in the middle, giving a technical description of DMSO+PTSO+DMSO. The coaches are of integral aluminium alloy construction based on a steel underframe. Each 3-car set can seat up to 220 people, and following the standard practice in the Glasgow suburban sector, peak time services can be formed by operating two units in multiple to form a 6-car train.
Since 1999, they were mostly found working on the Cathcart Circle Line services to Cathcart, Neilston and Newton. The Class 314s have also operated the Paisley Canal Line during off-peak times following the electrification of the branch in November 2012. A small number of units also worked Inverclyde Line services to Gourock and Wemyss Bay, mostly during peak hours. They were replaced by Class 380 trains on this line, but then returned to share the service with 380s. They are also seen on the Ayrshire Coast Line occasionally, particularly when extreme weather affects the availability of other ScotRail EMUs.
The Class 314s are due to be retired in 2019, when delivery of Class 385s allows for the Class 318s and Class 320s to be cascaded on to lines previously operated by the 314s. Scotrail announced that replacement by 385s would begin on the Inverclyde Line from 19 May 2019, with 314s only taking three early morning Gourock services each day.
Units 314208 and 314212 were severely damaged when they were "drowned" in an Argyle Line tunnel following the River Kelvin bursting its banks in torrential rain at the end of 1994.
Overhaul and refurbishment
In May 2006, a limited mechanical overhaul programme to the units was initiated, with upgraded door mechanisms and upgrades to the electrics and Automatic Warning System (AWS) equipment. 314202 lost its classic Strathclyde orange/black livery (the last remaining operational multiple unit in Scotland to carry the old livery) in favour of the carmine/cream scheme when it passed through Glasgow Works at the end of November 2006. 314206 entered Glasgow Works on 20 July 2007. This was to be the final unit to receive a major overhaul, pending a decision on the future of the Class 314 units.
In 2009/2010, all Class 314s received a life extension overhaul (C5E). The work included:
- Bogie change
- Cab works
- Various other modifications
In 2011, the Class 314s underwent a C3 overhaul/relivery at Railcare Springburn. All 16 sets were refurbished internally, whilst five units received the new ScotRail saltire livery.
- Any corrosion repairs required
- Relivery (5 units only)
- Internal repaint
- Internal lino replacement on floor
- Replacement seat inserts/covers
- Full bogie/buckeye overhaul
- Further reliability upgrades
In September 2008, the Scottish Government's agency Transport Scotland announced that all ScotRail trains (including from the Strathclyde Partnership for Transport) would be eventually repainted in a new, blue livery with white Saltire markings on the carriage ends. Relivery of the first unit - 314 212 - took place in spring 2011.
In 2016, 2 other Class 314 units (314209 & 314214) were also repainted into the Saltire livery. 314201, 202, 205, 206, 207, 210, 213, 215 & 216 all remained in the debranded SPT Carmine & Cream livery. These units are now the last units (apart from one car of the preserved Class 303) to carry the SPT Carmine & Cream livery.

Withdrawal of the units began on 21 September 2018 when units 314207, 314212 and 314213 were retired from service, although 314207 and 314213 were temporarily returned to service on 5 October 2018 due to unavailability of the newer Class 385s fleet. On 9 January 2019, 314212 was taken to Glasgow Works at Springburn where it was stripped of spare parts before being delivered by road to England for scrapping; it was the first unit of the fleet to be scrapped.
As of September 2019, there are currently 7 of these trains in service. These are 314202, 314203, 314205, 314209, 314210, 314214 and 314216.  All remaining Class 314s will be withdrawn in December 2019.
