 560 HP diesel engine, with electric transmission to two traction motors mounted on the rear bogie. The seating capacity of the power cars was 45, however after providing for wheelchair accommodation, this was reduced to 42. The vehicle also incorporated a guards/parcel compartment. The intermediate coaches were fitted with an additional door on each side to aid passenger flow and had a capacity of 87. The driving trailers had a small cab built at one end, which necessitated the removal of six seats. This cab was set to the left to preserve the gangway connection, so that two train sets could be coupled together and still allow passengers to travel between the trains. All three types are of integral construction, however the power cars, because of their weight, also have an underframe. They were similar to the UTA 70 Class

. The railcars proved so successful that a second series was ordered in 1975, entering service in 1977/78.

Each vehicle was numbered individually, with power car numbers running from 67 to 69, and 81 to 99. The Intermediate Trailers were numbered 761 to 780 and the Driving Trailers were numbered 731 to 756. Power cars 81 to 89 were built between 1974/1975, while 67 to 69 and 90 to 99 were built between 1978/1979. Intermediate Trailers 761 to 764 were also built between 1974/1975, with 765 to 773 being completed between 1978/1979. Likewise, the Driving Trailers were also completed in batches, with 731 to 739 built between 1974/1975 and 740 to 751 built between 1978/1979. The additional coaches were conversions from BR or old NI Railways loco-hauled coaches, and were not original Class 80 vehicles. These were Intermediate Trailers 752 to 756 and Driving Trailers 774 to 780. During the mid 1990s the surviving vehicles were all renumbered by Translink, by adding 8000 to the their numbers to avoid duplication with the bus fleet opearated by Ulsterbus and Citybus, also Translink subsidiaries.

Refurbishment

Despite the increasing age and obselesence of the Class 80, the lack of available rolling stock has meant that NIR has been forced to retain a number of units, even in spite of the entry into service of the new Class 3000. As of 2009, NIR will maintain up to three 4-car units for use on passenger services. These will see a pair of 2-car units, a power car and driving trailer, coupled back to back. Six trailers will be refurbished and fitted with central door locking to enable them to remain in service until the new Class 4000 units enter service. [742 had been nominated for retention but was scrapped in May 2008 and replaced in the programme by 752]

The power cars are being overhauled at LH services in Staffordshire and the trailers at York Road works in Belfast

Set 89-733-738-69 remained in service until May 24, 2008

97 was converted to a Sandite spraying vehicle in 2006 and in 2006 and 2007 was used on these duties coupled to 89. On October 1, 2008 97 had a test run with refurbished 82 and this pair are being used for Sandite trains until December 2008

Set 93-754-749-94 has been sporadically on test since 23 July 2008. As of 3 November 2008, it has been reported than regular passenger services have been commenced with this set.

In 2009, 8097 was on Sandite duties again with 8082. During October 2009 while out on Sanditing Duties the engine in 8097 exploded. 8082 struggled with haulling dead 8097 so it was decided to add 8094 to back of the train to help it along.

On the 17th December 2009, a second refurbished 80 class was deployed onto the Larne Line. The current sets on the Larne Line are 8090-8749-8752-8093 and 8094-8754-8747-8082. The third refurbished set is currently stored at York Road and it consists of 8069-8733-8738-8089.

On 26.1.10- 8089 entered passenger service with 8093, 8090 was taken off the set on Saturday 23 January 2010. 8090 is currently being stored at the south end of the south sidding at York Road.

It has been rumoured that 8082 has now been withdrawn from service following from an engine fire. 82 has been fixed and returned to working order after the fire in Larne

In 2011, the entire Class 450 fleet, together with the remaining Class 80 units, was listed by NI Railways for disposal.

The final Class 80 units were withdrawn from passenger service on the 25th September 2011. However, a four car unit remains in service as NIR's sandite
