458 is the sole survivor of NIR’s nine-strong 450 Class, built by BREL between 1985 and 1987. The bodies were constructed at York and the rest of the fitting was carried out at Derby. As with many railway vehicles in Ireland, they were a quick and cheap fix to rolling stock shortages – they were essentially 70 Class engines, generators, traction motors and other electrical equipment on British Rail MkI underframes housed in Mark 3 suburban bodyshells similar to BR EMUs and Sprinter DMUs of the era. As there had only been eight 70 Class power cars, the donor parts for the ninth 450 was from 80 Class No. 88 which had been written off in the Hilden crash in 1983.
Each 450 was named after a Northern Irish castle, and as a result were known by enthusiasts as the ‘Castle Class’. Our own 458 is named for Antrim Castle. It consists of three semi-permanently coupled vehicles: A driving trailer (68 seats); an intermediate (78 seats); and a power car (38 seats). The power car also houses the guard’s compartment, right next to the English Electric 4SRKT engine. The seating has now been reduced as a result of modifications made by us to accommodate a buffet area and a different configuration in the driving trailer to add additional wheelchair spaces and alternative seating.
458 began its NIR career in January 1987 on the Larne line, where it would spend most of its working life. Unlike the 70s that had went before them, the 450s were ideal for suburban services, with high density seating and five double doors on each side for optimal passenger flow. In 1996, it was renumbered as 8458 to prevent conflict with bus routes on Translink’s new computer system, though we have since removed this prefix.
458 underwent life extension work in 2005, gaining an overhauled interior and, uniquely among 450s, CCTV. With the arrival of NIR’s 4000 Class trains in 2011, withdrawal of the 450s was on the cards and it was then that they lost their nameplates. 458 became the last 450 in service, with its last passenger outing in March 2012. It was stored at Central station and later York Road until September 2014, when it was moved by road to Downpatrick in a two-day operation having been acquired by us in February that year.
Our intention with 458 was to convert it into our new buffet train to allow our then-in-use one to come in for overhaul. However this didn’t stop it from putting in passenger appearances on an ITG gala in October 2014, as well as at its official handover ceremony in November. Work began on the conversion in Winter 2015, though as tends to happen more urgent priorities kept arising and as a result this work was protracted until August 2018.
Among other work, a buffet compartment and kitchen facilities have been installed in the intermediate and the original 3+2 seating has been replaced with 2+2 to improve accessibility, whilst tables have been installed in every seating bay. The driving trailer has been gutted to allow future conversion to a Santa’s Grotto for our Christmas operations, and the guard’s compartment has been turned into a store. Wheelchair accommodation, previously housed in the guard’s compartment, has been moved to the intermediate.
458 officially entered service as a buffet train in August 2018, though due to electrical faults it was hauled out by a diesel locomotive using a translator carriage for the time being. This carriage, DBSO No. 8918, has both conventional coupling hooks and drop-head buckeye couplings at each end, allowing it to couple to 458 and our diesel locomotives.
458 was the star of the Derry Girls series three episode ‘stranger on a train’, a major filming project for the railway. Following extensive repairs and testing of doors and electrical systems (and the traincrew!), 458 entered public service in Summer 2022, complete with an on board buffet an ex-Irish Rail Mark 3 seating in the driving trailer. A far cry from commuter trains on the Larne Line!
