No fewer than 6 of Sir Nigel Gresleys streamlined A4 4-6-2s have been preserved. 4 in Britain and one each in Canada and the USA. With the latter. 2 shipped over from North America. A unique gathering of all 6 took place at the National Railway Museum in Shildon in 2014. This was probably the last time all locomotives will be together as the 2 visitors have since returned over the Atlantic to their respective museums.
