New Zealand British Rail Mark 2 carriage
Résumé
The New Zealand British Rail Mark 2 carriages were built by British Rail Engineering Limited for British Rail in the early 1970s. From the mid-1990s, 150 were exported to New Zealand. After being rebuilt, refurbished and re-gauged, they entered service with a variety of operators on New Zealand's railway network. The carriages generally replaced older NZR 56-foot carriages, some of which had been in use for almost 70 years.
British Railways Mark 2
The British Rail Mark 2 was the second design of carriage by British Rail (BR). The first was built in 1963.
Between 1964 and 1975, 1,876 Mark 2 carriages were constructed at Derby Litchurch Lane Works. There were seven sub-classes, 2 & 2A to 2F. The Mark 2D to 2F classes, built from 1971 onwards, had air conditioning and could be distinguished from earlier sub-classes by having sheet glass windows. All of the carriages imported into New Zealand were from these latter three sub-classes. When introduced they were used on all mainline services in Great Britain. They were superseded by British Rail Mark 3 carriages.
Because of construction constraints, most railway lines in New Zealand have a limited loading gauge. Great Britain uses , but its loading gauge is only slightly larger than New Zealand's . This means that British Rail rolling stock like the Mark 2 carriage can run on most New Zealand lines after gauge conversion. To fit the New Zealand loading gauge, the Mark 2s were lowered on their new bogies by 25 centimetres.
New Zealand rail operator Tranz Rail and heritage operator Mainline Steam Heritage Trust bought 69 Mark 2 carriages (one damaged by fire after arrival) in 1996. Eight were extensively refurbished for the Wellington–Palmerston North Capital Connection, classified S (for Scenic), with new Japanese bogies and new auto plug doors and interiors. The refurbishment proved more costly than expected, and the remaining carriages were laid up until a rebuilding programme began for the Auckland Regional Transport Authority for Auckland suburban trains.
