LNER Class A4
The Class A4 is a class of streamlined 4-6-2 steam locomotive designed by Nigel Gresley for the London and North Eastern Railway in 1935. Their streamlined design gave them high-speed capability as well as making them instantly recognisable, and one of the class, 4468 "Mallard", holds the world record as the fastest steam locomotive. Thirty-five of the class were built to haul express passenger trains on the East Coast Main Line route from London Kings Cross via York to Newcastle, and later via Newcastle to Edinburgh, Scotland. They remained in service on the East Coast Main Line until the early 1960s when they were replaced by Deltic diesel locomotives. Several A4s saw out their remaining days until 1966 in Scotland, particularly on the Aberdeen - Glasgow express trains, for which they were used to improve the timing from 3.5 to 3 hours.
Rotorua Express
The Rotorua Express has the distinction of being the very first express passenger train in the world to be hauled by Pacific locomotives, when Q349 hauled it out of Auckland on Christmas Eve, 1901. This was the start of a worldwide trend, with such trains as the 20th Century Limited, Orient Express, Flying Scotsman and many more all sporting such locomotives of the type in later years. The world's fastest steam locomotive, is also of the same type.
