British Railways Mark 2 : ウィキペディア英語版 | British Railways Mark 2
The Mark 2 family of railway carriages were British Rail's second design of carriages. They were built by British Rail workshops (from 1969 British Rail Engineering Limited) between 1964 and 1975. They were of steel construction. ==Introduction==
The Mark 2 has a semi-integral construction, giving it more strength than a Mark 1 in the event of an accident, although a key driver of the changed construction method was to overcome the serious corrosion problem point in the Mark 1 at the base of the body, where it was attached to the underframe. Other changes of design, such as the window units, were for the same reason, which had become a serious problem in Mark 1 vehicle maintenance costs. Revised painting methods were also part of this, which coincided with the change of livery from maroon (dark green on the Southern) to the blue and grey that Mark 2 coaches wore for much of their lives (some of the earliest Mark 2 coaches had the old livery at first). The Mark 2 coach was one of the mainstays of the InterCity network, but new rolling stock introduced in the post-privatisation era has resulted in most being withdrawn. Since their withdrawal from most main line duties, Mark 2 coaches have played an increasing role on private rail tours, charter trains, and on heritage railways. Since 1996, over 140 Mark 2 carriages have been exported to New Zealand, where they are still in mainline service (as of 2013).
