Our own drawings
- Six small side-view drawings of the same steam locomotive in different colours. 1923: number 1472, LNER Apple Green. 1924: number 4472, now named Flying Scotsman, Apple Green. The Second World War: wartime black, like all railway stock. 1948: number 60103 for British Railways, blue for a time, then BR Green. 1963: bought by Alan Pegler and back in LNER colours. 2016 to today: number 60103 again, in BR Green.
Our own drawing - A side-view drawing of a steam locomotive, its tender and the first carriage. A dashed gold arrow runs from the carriage, through a narrow passage along the side of the tender, to the cab of the locomotive. Labels: the fresh crew walks from the train, through a narrow passage in the tender, to the footplate, so the train need not stop.
Our own drawing - A bar chart of steam speeds in miles per hour, with bars starting at 60mph. Flying Scotsman, 1934: 100mph, first officially in the UK. City of Truro, 1904: 102mph, claimed. The LMS before 1938: 114mph, the British record before Mallard. Germany, May 1935: 124.5mph, the world record before Mallard. Mallard, 3 July 1938: 126mph, the steam world record, still standing.
Our own drawing - A simple line on a green background from London King’s Cross to Edinburgh Waverley, labelled non-stop, about eight hours. A note says it is our schematic of the East Coast Main Line, not to scale, with the stations between left out.
