This week's subject on the Post is Scarborough, the seaside town in North Yorkshire. In his new book To the Sea by Train: The Golden Age of Railway Travel, Andrew Martin recalls the days when day-trippers and holidaymakers arrived in their thousands by excursion trains until the advent of cheap flights and package holidays caused numbers to dwindle, but it's still possible to arrive from York at the grand station and enjoy this lively place with plenty to offer. (The LNER promoted its seaside destinations with imaginatively glamorous posters such as this from 1936 which features the South Bay Pool by Edmund Oakdale.)
