The landscape format is, and always has been, the dominant shape for jigsaw puzzles and easily accommodates a picture of a train or locomotive. The vertical format is quite rare in comparison but can produce a very effective puzzle. The two puzzles I have chosen from my collection, for today's post, 24th September 2011, emphasize the latter point.
The first picture shows a Victory wooden puzzle of 100 pieces titled Southern Railway Express "Bournemouth Limited", from the mid 1930's (T6). The express was introduced in July 1929 and ran from London's Waterloo Station to the popular Dorset seaside town. The service was curtailed during World War II but reinstated in 1945, without its name. However, the origin of the express was in a 1911 service when the London & South Western Railway began a Waterloo - Bournemouth express until the outbreak of World War I. The 'Bournemouth Limited' was renamed 'The Royal Wessex' in 1951 under British Railways. The locomotive heading the Southern Railway (SR) green passenger stock in the jigsaw picture is SR 'King Arthur' class 4-6-0, No 789 Sir Guy. The class was originally designed by Robert Urie of the London & South Western Railway between 1919 and 1922. From 1923 the Chief Mechanical Engineer (1923-37) of the SR, Richard Maunsell, redesigned the class and built additional locomotives. The class eventually totalled seventy four.
The picture in jigsaw number one incorporates a wider angle and a higher viewpoint than jigsaw number two and hence, may appeal more to pictorialists.
