Overview: Michael Portillo's Edwardian railway guide takes him to the city of Liverpool, where King Edward VII had recently laid the foundation stone for a grand Anglican cathedral at the top of St James's Mount. The young winner of a competition to design the building was a Roman Catholic from a family of architects. His name was Giles Gilbert Scott. Michael takes a trip down his own memory lane in Maghull on the outskirts of Liverpool, where he discovers a childhood favourite - a miniature tank engine with three carriages in dark red - made by Frank Hornby. Heading west to Wales, Michael skirts the coast to reach Abergele, where he visits the romantic ruined Gwrych Castle. He learns the story of its fervently Welsh countess, the last of the Lloyds of Gwyrch, and admires the dedication to her legacy of a young man devoted to restoring the estate.
